Cognito - Deaver 2011 - 2019 GM 2500HD / 3500HD 4" Lift Rear Leaf Springs # K97

Deaver # K97 / Cognito # 210-90238.

Let's start with the easy stuff. Performance Lifts sells these leaf packs as a matched pair. The listed price includes 2 spring packs. No more and no less. Shipping leaf springs is expensive because they are oversized and very heavy. They cannot be easily boxed. Because of this the UPS shipping charges can be very expensive. Performance Lifts cannot afford to ship this item for free. That means you have to pay for shipping. You can add this item to your cart and then get a shipping quote by entering the state and ZIP code the order will be shipped to. The system will provide you with an instant shipping quote.

Again, Performance Lifts only sells the Deaver K97 / Cognito 210-90238 spring packs in pairs. One pair of Deaver Spring Company Leaf Springs includes two complete leaf packs. Replacement U-bolts may be necessary when installing Deaver leaf springs. If you currently have a lifted truck that uses rear lift blocks you will most likely need a shorter set of U-bolts. U-bolts are NOT included with Deaver springs! If your truck is currently stock height the installation of Deaver +4" springs will also require the installation of extended length shock absorbers. Shock absorbers are NOT included.

Deaver does NOT use a traditional full length overload leaf in their K97 spring packs. This means if you tow or haul extremely heavy loads the use of Deaver K97 spring packs will most likely require the addition of an auxiliary air bag system to support your additional tow or haul weight. Otherwise the rear packs will sag under the weight and the back of your truck will squat down. That is the price you pay for using a high arch spring pack with improved on and off-road manners.
