Rein Automotive Anti-Vibration Mounts
Anti-vibration parts dampen vibration harmonics from the engine and driveline components to rest of the vehicle, reducing vibration and noise which can be felt and heard while the vehicle is in operation. Rein Automotive anti-vibration mounts match the design and function of the OE parts. Select the mount needed for your application.

Global West Suspension Shock Crossmembers
Global West shock crossmembers provide the needed support to the rear shock mount area on specific year/make and model vehicles. The reason for the rear shock mount is due to the use of air shocks, as well as coilover applications. When installing a coilover kit or air shock, you're transferring the load of the cars weight from the lower control arm location to the shock location, which was never designed to support the weight of the vehicle. When you add shock crossmembers, they strengthen that area and support the new load, reducing the possibility of damaging the frame at that location. When you need quality suspension parts, choose Global West Suspension.

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

Dinan Carbon Fiber Strut Tower Braces
Dinan carbon fiber G8x strut tower braces provide additional rigidity and sharper handling to the chassis by reducing flex under hard cornering conditions. With more control, spirited driving becomes easier and infinitely more enjoyable. The lightweight braces are designed with maximum function in mind—and include linking structural elements that completely change the OEM 2-piece strut bar set into one blended system that offers additional strengthening against flex. Not one to take a back seat to functionality, aesthetics are also elevated beyond simple steel bars into striking carbon fiber (matte or gloss) with accents that tie in effortlessly into the highly geometric and angular factory engine bay for an OEM+ feel. The imposing carbon fiber braces can be installed in a matter of minutes and used in conjunction with either the stock or Dinan intake systems. While the braces were designed to specifically tie into the latter for a harmoniously balanced and unified appearance, they can also stand on their own and elicit nearly as equally an impressive visual. Product details:: * Improved chassis rigidity * Decreased flex during cornering * Lightweight: 5.6 lbs. lighter than stock (Dinan carbon fiber: 2.8 lbs. vs. OEM steel: 8.4 lbs.) * 2x2 twill carbon fiber with inset aluminum mounting points for increased strength and improved visual appeal * Designed to mesh seamlessly with the Dinan cold air intake, creating an aesthetically unified engine bay * Bolt-on installation using factory mounting hardware
