This new 4 System capitalizes on Toyota Tundras 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 with a .120 wall DOM arm with heavy duty extended range ball joints that provide additional strength to the front suspension. 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 a spacer system to retain the factory Coilover shocks and rear Performance shocks.

Our Tundra systems feature extended length ductile iron steering knuckles that have been designed to operate within the factory steering geometry. This geometry provides proper turning radius with oversized tires and wheels. The factory lower control arms are relocated with high arched 1/4 in. thick steel crossmembers with an integrated differential skid plate for protection against offroad obstacles. The factory front sway bar is retained and utilizes sway bar drops. The Performance system includes our Dirt Logic 2.5 Resi Coilover shocks for aggressive offroad use with a good highway ride and utilizes a 3 in. block and u-bolt system for rear lift.

The 2.5 Lift system for late model 2013 3500 Rams, with Radius Arm front suspension, features more than just basic spacers. Dodge designed the front coil springs with a large bow to increase vehicle stability and handling. Unlike other flat spacers on the market, Fabtechs angled spacers retain this important feature preserving the factory ride characteristics. The front shocks are replaced with longer length units to allow for full suspension travel while improving the damping of the front suspension. Extended length bump stops are included in this kit to prevent the coil springs from binding at full compression while also eliminating Trac Bar interference.
