You're building your truck for a purpose, paying attention to every detail, every connection, and every movement. We built our system this way, too. With this all-new, engineered-from-scratch system, you can stop using junkyard parts to modernize your pickup and can bolt in the handling and performance you’ve always wanted.

Designed specifically for 65-79 F-100s, the front system is 3.75" narrower than a Crown Vic, providing ideal handling and allowing fitment of larger wheels and tires. The system also saves 150 lbs of weight and provides 3” to 5" of drop with standard spindles and 5" to 7" with drop spindles.

Everything you need is included, all the way down to the hardware. All components included in these systems are proudly made in QA1’s Lakeville, Minnesota facility. All QA1 shocks are 100% dyno tested and serialized.

WHAT'S INCLUDED? 

  • Adjustable Shocks
  • High Travel Springs
  • Coil-over Hardware
  • Upper and Lower Control Arms
  • Upper and Lower Crossmembers
  • Rack and Pinion Steering
  • Stock or Drop Spindles
  • All Required Nuts, Bolts, etc.

F-100 Front Coil-Over Conversion System

WHAT ELSE DO I NEED TO KNOW? 

  • The system does not connect the steering wheel to the rack.
  • The spindles are designed to work with brake systems that would fit ’79-’81 Camaros.
  • Are you looking for additional stability for more aggressive handling? Find a front sway bar (#52865) on our Ford Sway Bars page.
  • Want to upgrade all four corners? We also offer an F-100 rear suspension system.
