This 4in System capitalizes on Toyota Tundra's large wheelwell opening to allow use of 35in tall tires with minimum lift height. The design of this 4in System is a new style of suspension that delivers improved performance with fewer parts, and comes with an affordable price. The system includes replacement upper control arms constructed with .120in wall 4130 Chromoly and 1in FK Stainless Uniballs. Heavy duty extended length steering knuckles are included to provide proper functionality of the factory ESC (Electronic Stability Control) with 35in tall tires. The knuckles retain the stock track width keeping the tires under the front fenders. The front differential is relocated to keep CV angles proper during the full range of travel. Front bump stop extensions and brake hose relocation brackets complete the front suspension. Rear lift comes from a 1in lift block and u-bolt system to level the stance of the vehicle. The 4in System is available with Dirt Logic 2.50 front Coilovers and rear Dirt Logic 2.25 shocks for increased travel and aggressive offroad driving.
