QA1 GM K-Members
QA1's tubular K-member for the 1982-1992 Chevrolet Camaro/Pontiac Firebird (F-body) is a significant front-end upgrade. Designed for reduced weight and increased clearance for headers and oil pans, QA1's K-members make a great upgrade for both street performance and track vehicles. QA1's engineers prioritized superior strength when designing these K-member components which reinforces the front-end unibody structure while optimizing weight savings. Unlike other K-members that lock you into a single setup, QA1 K-members offer unmatched versatility with their modular engine mounts (sold separately) that let you switch between engines and transmissions without needing a new K-member. No other K-member offers this level of adaptability, making QA1 the ultimate choice for a seamless build. The K-members offer the flexibility to be used with either coilover struts or QA1 spring sliders, depending on your performance goals. Coilover struts, like QA1's adjustable Proma Star Struts, can also provide a significant performance boost for your 3rd Gen Camaro or Firebird with the ability dial-in the perfect ride height. For those looking to achieve the perfect stance with greater negative camber, while accommodating wider wheels and tires, inboard spring sliders by QA1 are another great option. The inboard spring slider option also helps to maintain spring loads near the factory position on the QA1 K-member. Features and benefits: * Steel suspension subframe crossmember * High-strength design with powdercoat finish * The unique design of QA1's K-members allows the use of interchangeable engine mounts (sold separately) for easy engine swaps—choose from modular engine mounts (sold separately) that either allow you to reuse your existing small block engine and transmission combination or swap to a big block Chevy, or more modern LS and Gen V LT * Substantial weight savings—shedding 32 lbs. while increasing clearance and enhancing accessibility to the front of your car, this is an ideal upgrade! * Compatible with QA1' spring sliders or QA1's coilover struts (sold separately) * You can make your driveline swap even easier by using QA1's transmission crossmembers and torque arms (both sold separately) * Bolt-in installation—QA1's commitment to thoughtful product design is evident in their fully bolt-in kits, providing an easy installation process Fitment Notes: Must use QA1 lower control arms (sold separately). Not compatible with factory coil springs. Must use QA1 coilover struts or QA1 spring slider kit (both sold separately). Engine mounts sold separately.
