This new Gen II system retains the factory track width keeping the tires under the fenders for a clean appearance. With the factory track width retained the front Sway Bar utilizes the stock end links and mounting holes keeping the leverage on the bar proper. There are no CV spacers, impact struts or add a leafs required for installation. The front differential is relocated in a manner so that when driving at higher 4 wheel drive speeds vibration is reduced. The GEN II Basic System utilizes a simplistic upper Coilover spacer that provides lift from the top of the shock rather than bottom up with reduced install time. Rear shocks are Performance Twin Tubes. All bracketry and the skid plate is constructed of 1/4" thick steel for maximum strength and proven reliability. The system passes FMVSS 126 standards for stability control functionality as tested by an independent lab. Use 35/1250R17 tires w/ 17x8 wheels w/ 5" BS w/ minor trimming.
