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.\nBall Joint Control Arm Lift System; 3.5 in.

This innovative 4-System suspension upgrade leverages the truck's large wheelwell opening to accommodate 35-inch tall tires with minimal lift, enhancing off-road capability while maintaining a factory-like appearance. The system features a simplified design with fewer parts, ensuring quick and straightforward installation without the need for drilling, welding, or cutting, typically completed within 2 to 3 hours. The kit includes high-quality tubular steel upper control arms with 1.5-inch OD x .120-inch wall DOM tubing, providing increased strength and durability. Heavy-duty forged torsion bar keys and a heavy-duty extended-length steering knuckle preserve the factory Electronic Stability Control (ESC), ensuring proper functionality even with larger tires. The front differential relocation maintains correct CV angles during full suspension travel, while bump stop extensions and brake hose relocation brackets ensure reliable performance. Rear lift is achieved through a 1-inch block and u-bolt system, leveling the truck's stance for a balanced look. The kit also offers an optional spacer system to retain factory coilover shocks and performance shocks for a customizable ride quality. With built-in caster adjustment, high-travel oversized ball joints, and no ground clearance loss, this system delivers a blend of off-road capability and on-road comfort.
