QA1 67-69 GM F-Body Double Adjustable Rear Four Link Kit w/ Narrowed 9in Housing

QA1 is well-known for making performance suspension components that help you get the most out of your classic muscle car. If you're looking to upgrade your 1st Gen Camaro or Firebird, this all-in-one rear suspension kit is a serious step up from leaf springs. It combines QA1's popular adjustable 4-link system with a custom-built, narrowed 9-inch rear housing, so you don't have to hunt for parts or guess at measurements. This kit is designed to give you a perfect fit and make installation as straightforward as possible, getting you back on the road faster.

This kit lets you ditch the leaf springs for a modern setup that offers adjustable ride height, improved ride quality, and precise control over your rear suspension's instant center. The narrowed 9-inch housing is built tough, featuring a fabricated center section for strength, formed trailing arm brackets to resist flex under load, and heavy-duty 3-inch axle tubes. It comes ready for up to 650 horsepower with 31-spline axles, and the housing itself is rated up to 800 horsepower. You'll also appreciate the convenience features like a drain plug, fill plug, and jack pad, making maintenance much easier. The housing has a 54-3/4 inch wheel mounting width, uses Big Ford 'New Style Torino Flanges' for brake compatibility, and has a 5x4-3/4 inch bolt pattern with 1/2-inch wheel studs.

While this kit is designed for a bolt-in installation with minimal welding required, it's recommended to use QA1 Subframe Connectors for optimal performance. You may also need to modify your exhaust system to clear the new setup. QA1 offers a limited lifetime warranty on their shocks when registered, and a 1-year warranty on the 4-link and 9-inch housing components for defects.
