This 4'' System capitalizes on Toyota Tundra's large wheelwell opening to allow use of 35'' tall tires with minimum lift height. The design of this 4'' 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 .120'' wall 4130 Chromoly and 1'' FK Stainless Uniballs. Heavy duty extended length steering knuckles are included to provide proper functionality of the factory ESC (Electronic Stability Control) with 35'' 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 1'' lift block and u-bolt system to level the stance of the vehicle. The 4'' System is available with Dirt Logic 2.50 front Coilovers and rear Dirt Logic 2.25 shocks for increased travel and aggressive offroad driving.

Arms eliminate upper ball join w/super strong 1 ID stainless American uniball. Additional caster is built into arms for greater align ability to help with problematic leveling kit alignments. Allows for increased wheel travel when used w/Dirt Logic 2.5 coilover shocks. Chromoly tubing reduces flex found in stock arms for more positive road feel. 4340 heat treated uniball pin fits into factory ball join taper without modification to the spindle for easy return to stock feature. Arms are direct replacements for factory arms on suspensions that require additional strength and align ability.
