Important Vehicle Specific Notes and Recommendations

Chevy and GMC 2500 and 3500 series trucks feature IFS front suspensions with torsion bar springs and heavy duty rear leaf springs. This configuration provides excellent towing and hauling capabilities, however, the front end is very particular to its ride height and the heavy springs produce a lot of "kick-back" so shock tuning and setup are critical for the best results. A few important setup notes for these trucks are listed below:

1. Front ride height is very easy to adjust by turning the torsion bar keys under the truck. While these trucks do benefit significantly from adding 1" to 1.5" of lift over average stock height, it is very common for people to over-crank the torsion bars above this range which causes ride quality to suffer dramatically. Filthy Motorsports highly recommends using a proper torsion key leveling kit and adjusting the front end to 1" of lift, and no more than 1.5" of lift.

2. Avoid adding heavy weight to the front end, especially on diesel engine trucks. The front suspension on GM HD trucks works much harder than Ford and Ram trucks with solid axles as the shocks are leverage 2:1 and the torsion springs are leveraged 5:1 on the lower control arms. Adding a 200lb. bumper and/or winch combination up front is the most that we recommend for good performance.

3. Keeping weight in the bed is an easy way to improve ride quality on full-size trucks. The factory springs require about 400-600lbs in the bed to reach their "sweet spot" and they will ride significantly harsher when unloaded. While King rear shocks will help significantly to control the springs, adding a fuel transfer tank or tool box in the bed will actually improve ride quality. If towing and hauling is not a significant portion of how the truck is used, Filthy Motorsports highly recommend softer rear leaf springs.

4. Tires and tire pressure are a big factor to ride quality on full-size trucks. Because the springs and shocks are dedicated to dampening and controlling the movement of a 6,000-7,000lb truck, they can't do much for small bumps in the road like cracks or small rocks. These small imperfections are the responsibility of the tires and the more sidewall a tire has (larger tire on a smaller wheel) and the better it flexes, the better it will absorb these bumps. We recommend learning more about tire pressures and how maximum tire pressures are not needed when the truck is not towing or hauling.
