  • Pro Comp Lifted Vehicle Warranty Program

    Choose Pro Comp and get the ultimate protection for your investment. Pro Comp has just announced Lift Shield, the new 5 year / 60,000 mile Powertrain Warranty available on Pro Comp’s most popular late model suspension systems. This new warranty is the first of it’s kind in the off road industry and is included for Free on qualifying systems.

     

    This unprecedented new warranty goes beyond the usual product warranty and actually protects the vehicle it is installed on. Now when you equip your truck or SUV with a Pro Comp suspension system you can do so with total confidence because Lift Shield covers the vehicles powertrain for the duration of the factory 5 year/60,000 mile warranty. If the vehicle has a powertrain issue in the first 5 years or 60,000 miles of service (whichever comes first), Lift Shield covers the cost of parts and repairs in the event that the dealer denies warranty coverage. Best of all, it is included for FREE. There is no extra charge for the added warranty protection. Certain terms and conditions apply.

     

    Here are the lift kits that qualify for this program:

  • 2015 Ford F150 Recalls

    If you (or someone you know) are an owner of the new 2015 Aluminum body equipped Ford F150 you may want to contact your local dealership. Ford is recalling a growing number of these new trucks. On certain trucks a fire risk may be present because the heat shielding may not have been attached properly. On other trucks a shaft that is part of the steering column could possibly separate leading a sudden loss of control. Ford says that they are unaware of any accidents caused by these manufacturing glitches. Because both faults could lead to injury or death it is highly recommended that you contact your dealership to see if your VIN is part of either recall.

  • Wheel Offset & Backspace Q&A

     

    PerformanceLifts.com receives 1000's of e-mails each year and a good percentage of those involve questions about selecting the correct size wheel for use on a leveled or lifted vehicle. Wheel offset and backspace are critical to ensure your tire and wheel combo fit your Truck or SUV correctly. A wheel with too much backspace may not even bolt up to the vehicle, a wheel with too little backspace may allow the tire to rub when turning. We've already put together a growing list of factory wheel sizes and the offset / backspace (available by clicking here) but customers have asked for more information. This instructional page is designed to explain how offset and backspace are related and how they can affect tire and wheel fitment on your vehicle.



    Question:
    Will the aftermarket wheels I am looking at purchasing stick out farther than my factory wheels?


    Answer:
    This question is best answered using an example. If your factory wheel is 8.00" inches wide and you install an aftermarket wheel that is 9.00" inches wide the width increase alone will push the outer wheel lip out by 1.00". In other words, the 9.00" wide wheel will stick OUT by an additional inch. Here is where Offset and Backspace become really important. If your factory 8.00" wide wheel has +25.4 (positive 25.4 millimeters) of offset it will have a backspace measurement of 5.50" inches. If aftermarket 9.00" wide wheel has -12mm (negative 12 millimeters) of offset the backspace measurement will be reduced to 4.53" inches. That means the change in offset has resulted in a change in backspace. More specifically the reduction in offset has resulted in a reduction of back space. That means the -12mm offset will push the aftermarket wheel OUT an additional 1.00" inch more than the factory wheel, which results in a total outer wheel lip width increase of 2.00" inches. The amount the wheel sticks OUT beyond the fenders will go up if you run an aftermarket wheel that is wider than your factory wheel. The wheel will stick OUT even more if the amount of offset or back space is reduced.



    Question:
    Will a (insert tire size here) fit with my lift? The lift /leveling kit manufacturer says it will!


    Answer:
    That depends largely on the width and back space of your wheels. Lift kit and leveling kit manufacturers will usually also recommend the wheel size for use with the maximum recommended tire size that will work with their lift. If a manufacturer says "Clears 35" Tires on 8" Wide Wheel w/5.00" Backspace" that means you need to follow those recommendations. Let's say that instead of running the recommended 8.00" wide wheel you decide to install an aftermarket wheel that is 12.00" inches wide. That means the new wheel will stick OUT approximately 4.00" inches more than the recommended wheel. A combination like that (35" tire on a 12" wide wheel) will in almost all cases cause clearance issues because when the tire and wheel go beyond the fender opening the tire is more likely to rub when turning. A general rule of thumb is if you want to run a WIDE wheel you will need to run a SHORTER diameter tire to ensure proper clearance when turning.



    Question:
    Why does the Lift / Leveling Kit manufacturer say I can't use my factory wheels with their lift? They are the same diameter and width as the recommended aftermarket wheels!


    Answer:
    Simply put, BACKSPACE! If a manufacturer states their product is not compatible with the factory wheel you need to pay attention to this information. The number one reason is because the factory wheel will rub the aftermarket suspension components. Some lift and leveling kits will replace factory steering and suspension components with ones that reduce the amount of clearance between the wheel and tire sidewall. A factory 17x8 wheel with 5.50" inches of back space may rub the suspension components, but an aftermarket 17x8 wheel with 4.50" inches of back space will not. In most cases the lift and leveling kit manufacturers will specify if their product is compatible with a specific factory wheels. For instance, with certain lifts a factory 20" diameter wheel can be safely used when a factory 17" wheel cannot. The reason for this is the opening of the 20" wheel allows for clearance with the suspension components that the 17" wheel does not.


     

    Question: I've found an aftermarket wheel I really like, but it's available in two different offset options. Which should I use?


    Answer:
    A number of wheel manufacturers will offer the same wheel style in different offsets. We recommend selecting the offset that best matches the recommendation provided by the lift or leveling kit manufacturer. Remember, as positive offset increases so does back space. You might find that one wheel offset will work just fine and the other is not at all compatible.


     

    Question: My buddy / Internet says I can run this size tire just fine, even though the manufacturer says I can't. What should I do?


    Answer:
    Will your buddy / Internet fix things if the tire and wheel combination you select doesn't work out right? If you spend $5000.00 on a bitchin' custom 22x12 wheel and tire setup that doesn't fit properly is your buddy going to fix that for you? We know the Internet won't. If you want to be sure the tire and wheel combination will fit properly we recommend you follow the lift or leveling kit manufacturers recommendations.

  • CST 2011+ GM HD Suspension Lift Information

    Starting with the 2011 model year General Motors did a complete re-design of the suspension and frame on the 2500HD and 3500 series trucks. This means that almost none of the products designed for use on a 2010 2500HD will fit a 2011 2500HD. GM made some very slight revisions to their 2015 model year but all of the products that CST offers for the 2011-2014 trucks will also fit the 2015. So if you've got a 2011, 2012, 2013, 2014 or 2015 Silverado or Sierra 2500HD / 3500 truck the products on this page will fit. Please note that some products may be engine or transmission specific. An example would be if a product is either Diesel or Gasoline specific that will be noted. If a product is 2wd or 4x4 specific that will be noted.

     

    CST Performance Suspension has been a leader in the aftermarket suspension industry for over two decades. CST is very well known for offering superior suspension lifts and accessories designed for the Heavy Duty line of Chevrolet Silverado and GMC Sierra trucks. Performance Lifts customers have been asking for help putting together complete suspension system for their trucks. We've created two separate pages for the 6-8" lifts and the 8-10" lifts.

  • ProComp 2014 Ram 1500 4x4 6" Lift Updates

    The latest addition to Pro Comp’s line of Federal Motor Vehicle Safety Standard (FMVSS) 126-compliant suspensions is their 6-inch system for the 2014 Ram 1500. The test was performed on a half-ton Ram truck equipped with the 6-inch Pro Comp suspension, 20-inch Pro Comp alloy wheels, and 35x12.50R20 Pro Comp Xtreme A/T tires as the only modifications to the vehicle.

    A wide array of outriggers and sensors were installed to monitor and ensure that the suspension system does not compromise the Electronic Stability Control (ESC) systems that are government mandated on all new vehicles. On the closed test course, the Pro Comp equipped vehicle was accelerated to 50 mph at which point the computer takes over. The robotically controlled wheel spins abruptly; left and right, up to 300 degrees in less than half a second and returns back to dead center causing the truck to change direction and begin to slide. This event caused the trucks ESC system to activate and regain control. When the data was analyzed, it conclusively demonstrated that the Pro Comp products did not interfere with the performance of the Ram 1500’s ESC systems.

    ProComp Ram 1500 FMVSS 126 Certified

    Ram is the only auto manufacturer currently offering a coil sprung rear suspension on their trucks, which created a unique set of challenges that have left other suspension manufacturers flustered. “As the only half-ton truck on the market with a standard rear coil springs and a diesel engine option, the new Ram 1500 is going to play a big role in new vehicle sales in the coming year,” explained Adam Trowbridge, Pro Comp Suspension Brand Manager. “Consumers want a more impressive performing suspension off-road, while still maintaining all of the vehicle’s safety features on-road. Pro Comp works hard to make sure our kits excel in both environments.” Unlike other manufacturers that have elected to do self-testing through laboratory simulation, Pro Comp’s testing was performed on a test track where the true capabilities of their products could be measured more accurately.

    If you are looking for a 6" Lift Kit for your new 2014 Ram 1500 4x4 truck the ProComp kit is an excellent choice. It has proven itself to be compatible with the factory Electronic Stability Control systems while still providing 6" inches of suspension lift.

  • 2014 Silverado & Sierra 1500 Updates

    General Motors has made minor changes to the suspension on the 2014 model year Chevrolet Silverado 1500 and GMC Sierra 1500 series trucks. The Leveling Kits designed for use on the 2007-2013 models will in most cases also fit the 2014 just fine. The complete Suspension Lift Kits however now fall under two different fitment categories: Steel Suspension and Aluminum Suspension. In order to purchase the correct suspension lift for your new Silverado or Sierra you need to know which front suspension type your truck has. The easiest way to do this is to look at the color of the front suspension components. If your control arms are Black there is a very good chance the control arms are STEEL. If the control arms are Silver the arms are Aluminum. One way to verify the material type is to perform the old magnet test.... a magnet will stick to steel but it will NOT stick to Aluminum. Please note that most Suspension Lifts are now specific to the suspension material type. If you purchase the wrong kit for your truck it won't fit!

    Here are a few suspension lifts that we currently offer for the new 2014 Silverado and Sierra Trucks:

  • 2011 Silverado 4x4 Wheel Fitment Question

    Customer Question:
    I am interested in the 4" CST lift for a 2011 Silverado Crew Cab 4WD.  I am interested in using either the Fuel Off Road "Throttle" (17x9)or(18x9).. or the KMC XD Series "SPY" (17x8) or (18x8) with a 295/70/17 tire. I know I need a 5"-5.5" backspacing but which one is recommended for the 8" wide wheel and the 9" wide wheel...5 or 5.5? Thanks!

    PerformanceLifts.com Answer:
    Keep in mind that regardless of the wheel width the back space remains a constant. As you increase wheel diameter (say from 17" to 18") you can generally run a wheel with more back space. If you wanted to run an 18" wheel our pick would be the 18x8 with 5.5" inches of back space.

    GMC Sierra Equipped with CST 4" Suspension Lift

    The CST recommended backspace requirement is the same for either wheel width. The reason CST specifies a backspace requirement and not an offset is because backspace is constant regardless of wheel width. CST's concern is a wheel with too much backspace could allow a larger than stock tire to rub the CST steering knuckle and possibly the upper control arm. CST prefers that customers run a wheel with less backspace as this provides an increase in clearance between the tire sidewall and the suspension components. Less wheel backspace = more clearance between the tire and the suspension. More wheel backspace = less clearance between the wheel and the suspension and this can cause possible rubbing issues. Looking at the chart below... you can see how a wheel with the same offset but different widths will have a different backspace. This is why suspension lift manufacturers will specify a backspace requirement and not an offset requirement.

    Wheel Offset & Backspace Chart

    An 18x8" wheel with 5" of back space and a 18x9" wheel with 5" of backspace will both have 5" inches of backspace. In this case both the 18x8 and 18x9 wheel should clear the CST suspension lift components when running a 295 series tire just fine.

    Running a wheel with more backspace will keeps the tires tucked in closer to the centerline of the truck. Wheels with less backspace will push the tire/wheel out and in most cases the farther the tire/wheel sticks out the more likely it is to rub when turning. An 18x9 wheel with 5" of back space will stick out farther by 1" over the 18x8" wheel with 5" of back space. If you want a narrower stance that keeps the tire inside the fender opening you will want the narrower 8" wheel with 5.5" of back space. The 18x8 5.5" wheel would be our first preference. If you prefer a slightly wider stance we would still recommend the use of a narrower 8" wheel but with slightly less back space.
