Get the Perfect Stance on your Classic Pickup

Engineered to make your truck handle while giving you ride height adjustability to dial in the perfect stance, these front and rear coil-over conversions overhaul your suspension to add modern-day performance and driveability into your classic pickup.

These kits include your choice of QA1's proven single or double adjustable coil-over shocks so you can change the valving to meet your specific needs. Along with a variety of high travel spring rate options, the shocks allow for ride height adjustability and are 100% dyno tested and serialized. With superior control over suspension movement, you can easily dial in the stance for a smooth ride and great handling characteristics. 

Easily bolt in this system – no welding required. Everything needed is included, all the way down to the hardware. All components in these systems are proudly made in QA1’s Lakeville, Minnesota facility.

  • On-the-car adjustable valving makes it easy to dial in your desired level of comfort and performance.
  • Designed to support larger/wider wheels and tires.
  • Easy, bolt-in installation - no need to remove the bed.
  • Made in the USA.
