This item is only available in black. The Red kit displayed is for promotional use only. Shock absorbers are NOT included with this kit and will need to be purchased separately. Please select your desired shock absorbers using the selection boxes located above this item description. Rancho engineered this kit to clear up to a 37" diameter tire when a high clearance front fender is used. A 37" tire will in most cases require trimming to clear properly. Using a wide wheel or a wheel with different than factory back space may cause rubbing issues when running a 37" diameter tire. Our advice? Stick with 35" tires unless you are willing to go through the additional work to properly clear 37's.
