Mopar Chassi Stiffening Kits

Stiffening your Mopar chassis is critical to future suspension improvements and performance. Our chassis stiffening products are hand crafted in the USA. Here you will find everything from total chassis stiffening packs to body frame connectors and fender brace kits. The factory engineers added stiffening to some areas, so they recognized the benefits of the bracing 40+ years ago. We've just got the benefit of seeing how these react to the added chassis stiffening. Any car will benefit from the additional chassis (unibody) stiffening, especially if you are increasing the horsepower or just want you car to feel more "solid" going down the road. Frame Connectors add strength to the middle portion of the unibody, our design maximizes the strength of these via cantilever beam engineering to increase the Section Modulus of Elasticity. This is twice as strong at half the thickness!! Torque Boxes distribute the brute forces placed on the Unibody at active suspension mounting locations; think front leaf spring hangers pushing the car forward on a 600hp launch! Inner Fender Braces add stiffening to a front frame rail system that was prone to twisting. The front Lower Core Support brace connects the extreme front ends of the front frame rails to help make them stronger and less prone to twisting. When you remove the flex from your chassis (Unibody) you allow the suspension to work as it is designed. Now you can adjust spring rate, roll resistance (sway bars) and shocks and actually see and feel the difference! Our kits goes further by moving your leaf springs inboard 3" per side and adding 4" of wheelhouse tire area for Maximum Tire size and width. Are these duplicates of the OEM factory Braces? No, we build a version we refer to as our Hot Rod Brace Upgrade. Some of the stiffening components fit in the factory location, such as the torque boxes and inner fender braces, other components just add strength to known weak spots on the unibody. Do these require welding? Yes, installing a Chassis Stiffening Kit requires them to be welded into position.
