Product Overview The QA1 lowering kit is an all-in-one solution for anyone looking to upgrade the suspension of their 2015-2020 Ford F-150. This kit includes both QA1's front Pro Coil Coil-Overs and Rear Drop Kit, which provide adjustability to achieve the perfect lowered stance, while providing significant improvements to ride quality and performance. 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" using drop spindles or 1"-3" with stock spindles. Lower the rear with a drop range of 3.5-5.5" with 1/2 inch increment adjustments. Heavy Duty Shock Design QA1 Engineers have tackled the challenge of supporting the weight and payload capacity of modern trucks by designing a 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 Flip Kit, Shackles and Hanger KitsQA1's Rear Flip Brackets, Shackle and Hanger Kits are the ultimate solution for lowering the rear of your truck without compromising ride quality.
