QA1 C1500 Suspension

QA1 C1500 Conversion Systems - Coming Soon!

1988-1998 C1500 Coil-Over Suspension Systems

Add modern performance to Chevy and GMC pickups designed for utility. QA1’s bolt-on front and rear systems will help you lower your C1500, while providing ride height adjustability on all four corners. It's the best way to get that perfect level stance. You can tailor the system to create the performance desired, so your daily driver truck can handle those corners and curves like a sports car.


*This suspension system will NOT work on 14-Bolt 454SS rear ends.*

The Easiest Bolt-In Solution for Adjustable Coil-Overs

Easily bolt on big suspension performance with ride height adjustability and better geometry. QA1 front conversion systems:

  • Integrate control arms with our coil-over shocks to lower the truck and create room for wider wheels and tires
  • Offer control arm weight savings of 25 lbs per side over stock
  • Offer up to 7 degrees of caster and a range of +2 to -3 camber
  • Significantly improve camber gain during cornering with the extended upper ball joint

The Level 2 system is great for street performance, while the level 3  is the perfect match for OBS owners with competition in mind while still allowing adjustability to cruise to the track in comfort.

Why Be Confined to the Limitations of a Leaf Spring?

Add modern performance to your Chevy or GMC truck, all without removing the bed of the truck. QA1 engineered a unique design offering 4-7” of drop to maximize handling without the inherent binding issues of other 4-link systems. Superior control over suspension movementhelps you easily dial in the stance for a smooth ride and great performance.

The systems come with unprecedented adjustability: the panhard bar, torque arm, trailing arms, bracket mounts, and shocks are all adjustable. They are truly independent of each other, so you don’t have to worry about one adjustment affecting another. Easily bolt in this system – no welding required. Everything needed is included, all the way down to the hardware. 


Front and rear sway bars are also available. All QA1 shocks are 100% dyno tested and serialized. All products listed are proudly made in QA1’s Lakeville, Minnesota facility.
