Featured Technology & Benefits


New front leaf springs with bolt style leaf alignment clamps, anti-friction pads, OE style rubber bushings and tapered leaves for long term performance and great ride qualtiy
1-1/4" Solid steel track bar with urethane mounts to properly center the axle
New front & Rear U-bolt with high nuts & washers
Rear 3" Block kit
Performance custom valved Zone Shocks included

This 4" system features new front leaf springs that are designed to not only ride great, but will hold up to the abuse super duty trucks are made for. Progressively valved shocks are designed to increase offroad performance and provide excellent ride quality. A heavy duty track bar is used to center the front axle and makes the kit much easier to install than a track bar bracket system. A 3" block is supplied for the rear to level the vehicle. This is the easiest installation and best value on the market for a 4" system.
