The B1 Body Lift by JKS offers an economical solution to tire clearance problems, without affecting center of gravity, spring rate or steering geometry like suspension modifications. Unlike universal designs commonly used by our competitors, JKS B1 Body Lifts are specifically designed to work in conjunction with the OE body mounts. Our B1 Body Lifts actually provide 1.25 Inch of additional tire clearance, as opposed to the standard 1 Inch provided by other manufacturers. The Jeep(R) specialists at JKS have found this to provide the ideal amount of tire clearance without exceeding the safe working parameters for severe off-road use. Furthermore, no modifications are required to the fuel tank, air conditioning, radiator, or brakes, unlike taller body and suspension lifts. Manufactured from premium Dura-Thane poly material with a hardness of 94 durometer, JKS B1 Body Lifts are designed to easily exceed the demands of four wheeling.
