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.

Ridetech MOMENTUM Chassis Kits
Ridetech, a leader in air and coil-over suspension systems for more than 30 years, proudly announces the launch of its MOMENTUM chassis kits. This all-new platform gives classic muscle car enthusiasts a clean-slate foundation for their next project—delivering modern handling, increased performance, and design flexibility beyond the limits of factory frames. Builders can now enjoy the benefits of a fully engineered chassis while tailoring the suspension to their preferred style of driving, whether that's comfortable street cruising, high-performance autocross, or full track use. Key engineering highlights include: * Ridetech's MOMENTUM Chassis Series is a new platform for classic muscle cars, offering modern handling, optimized suspension, and modular options, initially for 1968-1972 models * Optimized suspension geometry—the chassis re-engineers pickup points to improve camber gain, caster, roll center, and Ackermann steering geometry * Enhanced stability—the chassis is significantly stiffer than a stock frame, which reduces flex and increases structural rigidity for more predictable handling * Improved cornering—a new integrated sway bar helps reduce body roll and improve balance, leading to sharper cornering and greater stability * Confidence-inspiring control—the design provides improved handling for both daily driving and more demanding situations like autocross or track events * Increased tire and wheel clearance—the chassis is engineered to accommodate larger, modern wheel and tire sizes that would not fit on a factory chassis * More aggressive fitment—allows for wider tires (e.g., up to 275mm front and 295mm rear) with room for larger fitments, especially when combined with mini tubs in the rear * Adjustable ride height—the system allows for roughly a 2-inch drop from stock but can be adjusted to the desired ride height * Kit offers modular suspension options that allow for air or coilover setups * Chassis is compatible with existing Ridetech A-body suspension components * Engine and transmission flexibility provides provisions for various motor mount plates (small block Chevy, Olds, Pontiac, Buick, GMLS, or Gen 5 LT) and features an adjustable crossmember that adapts to popular automatic and manual transmissions
