Ride Height AdjustabilityQA1 lowering kits offer easy and precise adjustments for your truck's stance. Fully threaded front coil-over shock bodies provide adjustment without the use of clumsy shims or spacers, while our rear drop kits offer 2" of adjustment to dial in the final rake of the truck. Front coil-overs provide a drop range of 3"-5" with the included drop spindles. Lower the rear with a drop range of 4-6". Heavy Duty Shock Design QA1 Engineers have tackled the challenge of supporting the weight and payload capacity of modern trucks by designing the heavy-duty version of our Pro Coil system, which features an upgraded shock with polyurethane bushings and a 1" chromoly T-bar. The system's new bushing design was specifically chosen to withstand the daily use of trucks, rather than using spherical bearings.

With the simple turn of a dial, you can effortlessly switch between a comfortable cruise and a more aggressive feel.Rear Shackles and Hanger KitsQA1's Rear Shackle and Hanger Kits are the ultimate solution for lowering the rear of your truck without compromising ride quality.
