QA1 Suspension System R220-250N

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. The result is greater freedom to choose from readily available wheels and create the stance and look you want. MORE WHEEL OPTIONS, BETTER FITMENT The included 9-inch housing features a 56-1/8" wheel mounting surface width, 5" narrower overall than the factory 61-1/8" width. The narrowed design works with mini-tubs to give you greater flexibility in wheel width, backspacing, and offset, making it easier to achieve the aggressive look to match the performance. The housing includes 31-spline axles, Big Ford New Style Torino housing ends and dual 5x4.5" and 5x4.75" bolt patterns for compatibility with a wide range of brake and wheel combinations. IMPROVED HANDLING WITHOUT SUSPENSION BIND QA1's unique torque arm design allows the rear suspension to move freely without the inherent binding associated with many traditional suspension designs. The result is improved traction, suspension control and a more modern driving experience. DIAL IN YOUR STANCE Achieve an aggressive stance with an adjustable 4-7" rear drop. The panhard bar, torque arm, trailing arms, bracket mounts and shocks can be adjusted independently, giving you greater control over ride height, axle position and overall suspension setup.

• 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.
• Fine-tune ride and handling: Double-adjustable coil-overs provide independent compression and rebound adjustment for greater control over suspension behavior.
• Support performance-focused builds: 250 lb/in. springs provide a firmer setup for trucks requiring additional spring support.
• 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.
