Product Details

The QA1 Narrowed 9" Rear Suspension System is built for the 1965-1972 Ford F-100 RWD.

Upgrade the rear suspension of your 1965-1972 Ford F-100 with a complete QA1 Rear Suspension System, paired with a narrowed 9-inch housing and 31-spline axles. QA1's unique torque arm design improves handling and traction without the inherent binding of many traditional suspension designs, while providing an adjustable 4-7" drop. The narrowed housing is designed to complement mini-tubbed trucks while opening up more options for modern wheel fitment.

Features

  • Deeper offset wheels and tires: Narrowed 9-inch housing provides an additional 2-1/2" of clearance per side for mini-tub applications.
  • Improve handling and traction: QA1's torque arm design allows the suspension to move freely without the inherent bind of many traditional suspension designs.
  • Dial in the perfect stance: Adjustable 4-7" drop lets you get your F-100 sitting exactly where you want it.
  • Tune the ride to your preference: Single-adjustable coil-overs provide 18 positions of adjustment for comfortable cruising or more responsive handling.
  • More performance-focused spring rate: 200 lb/in. springs provide a firmer setup for trucks built with an increased emphasis on handling.
  • Fine-tune your suspension setup: Independently adjustable suspension components provide greater control over ride height, axle position and geometry.
  • Build around your preferred wheels and brakes: Dual wheel bolt patterns and Big Ford New Style Torino housing ends provide compatibility with a wide range of combinations.
  • Start with a complete, matched system: Suspension, coil-overs, narrowed 9-inch housing and 31-spline axles are packaged together to simplify your build.
  • Performance you can count on: QA1 shocks are 100% dyno tested and serialized.
