Unibody vehicles have subframes at the front and rear to which the suspension and drivetrain are attached. While this is a proven method of vehicle construction, when pushed hard in the corners or launched from a standing start, the chassis can flex and cause poor steering response and wheel hop and wheel spin. We have the components to make your unibody chassis more rigid, to improve handling and acceleration and provide a more solid feel, including subframe connectors, braces, stiffeners & reinforcements, crossmembers, bushings, mounts, and even complete K-members.
Subframe connectors tie the subframes together on unibody cars like the Chevy Camaro and Nova, Ford Mustang, Dodge Challenger, and the Mopar muscle cars of the 60s and 70s. We have a huge selection of subframe connectors, braces, subframe bushings, mounts, and much more for these vehicles and others. Each component is engineered to eliminate flex and provide strength and rigidity for the specific application. You might think working with subframes means a lot of complicated cutting and welding, but the fact is most parts can be simply bolted in place, with no modifications to your vehicle required.
Although it’s usually not the first thing enthusiasts think of when they want to modify their vehicles for performance, stiffening the chassis with subframe connectors, braces, supports, reinforcements, and the other components you see on this page should really be done first to create a strong and rigid foundation for other go-fast mods. Think about it – does it make sense to hop-up your engine to make more horsepower, or install firmer springs and shocks and fatter sway bars, if the chassis they’re attached to is just going to flex excessively when you launch hard and corner at speed? Unwanted chassis flex just uses up power that could be turning the wheels instead, and also causes steering to lack responsiveness and feel.
Besides improved traction and steering response, another benefit from the increased chassis rigidity provided by subframe connectors, braces, supports and reinforcements is less unibody structural fatigue. On some vehicles, repeated chassis flexing can actually cause the sheet metal to tear, and some models are notorious for problems in particular areas like the floor pan. The subframe connectors, braces and other chassis stiffening components we offer have been engineered by the top brands in the industry, manufacturers with many years of chassis and racing experience. These companies live and breathe performance, so you can reinforce your chassis secure in the knowledge that the parts you buy won’t interfere with other performance mods like headers and large tube performance exhaust systems.
The chassis experts at our subframe connectors and braces manufacturers carefully analyzed the needs of each vehicle, and created specific products to address chassis deficiencies, so you can enjoy the improved performance that comes from increased chassis rigidity. Check out the products on this page and punch in your year, make, and model to see what we have for your car. In addition to subframe connectors we offer crossmembers to support transmissions, transfer cases, and shock mounts, braces to strengthen K members and stabilize the front suspension during hard cornering, frame reinforcements, bushings to further solidify the body-to-subframe connection, mounts, hardware, adapters for transmissions and transfer cases, and even complete subframe kits for racing.
The subframe that supports the engine is commonly called a K member. Our K members are much lighter and stronger than factory K members, and provide additional clearance for aftermarket headers and oil pans. Some even allow other engines to be installed, so they’re ideal if you’re considering an engine swap. These K members are available for select sports and muscle car applications. They’re precision designed to bolt right in place and they’ll accept stock suspension components like lower control arms, sway bars, and steering rack and pinion. Some are also engineered to facilitate aftermarket suspension upgrades like coilovers instead of OE coil springs and shocks.
