Description

QA1 1988-98 C1500 front and rear coilover conversion systems are a great upgrade to your C1500 suspension. Each kit comes with QA1's proven adjustable coilover shocks—so you can change the valving to meet your specific needs—along with a variety of spring rate options. These shocks allow for ride height adjustability and are 100 percent dyno-tested and serialized. The QA1 C1500 front control arms and rear torque arms are manufactured from 12-gauge HSLA steel tubing for increased strength and are powdercoated for long lasting durability. Topped off with performance ball joints and low-friction, maintenance-free bushings. Complete with adjustable instant center, panhard bar, and pinion angle to allow you to adjust the system to your exact needs. This kit will add more stability and allows for optimum camber adjustment in a lowered truck. Easily bolt in this system--no welding or bed removal required. Everything needed is included, all the way down to the hardware.

Product Overview

Want better handling for your 88-98 C1500? Turn to QA1's handling suspension kits for the performance level and ride that best fits your needs. Available in two different levels of performance, these handling kits include our front and rear coil-over conversion systems. Level 2 is great for street performance and provides up to 4" drop in the front with drop spindles, while the level 3 system has up to 6" drop in the front with drop spindles and is the perfect match for OBS owners with competition in mind while still allowing adjustability to cruise to the track in comfort. Both levels provide 4" to 7" drop in the rear with exceptional adjustability options. This kit includes both front and rear tubular sway bars.
