Stifflers Suspension transmission crossmembers are engineered to deliver quality, fit, finish, and functionality. At the core of these kits are Stifflers' unique single-tube crossmembers—adding strength and stiffness beyond that of OEM versions, while offering versatility without the excess weight. They also allow more exhaust clearance. To install, simply slide the mounting sleeves and reposition the spacers to cover your application. They work with OEM and aftermarket transmission mounts, and will maintain your current pinion angle. Stifflers Suspension transmission crossmembers include low-deflection polyurethane bushings in the mounts to dampen driveline vibrations and noise, but for racing applications they can be replaced by optional solid bushings. Order the crossmembers designed for fitment on your make and model.

Stifflers Suspension weld-on subframe connectors are engineered to be stiff, lightweight, and easy to install. These full-length connectors are manufactured from 1.5 in. x 2 in. x .083 in. rectangular tubing. They are optimized using CAD/CAE software to provide the ultimate in stiffness, reduced weight, and maximized surface area between the subframe and connector. Stifflers subframe connectors feature crimped and welded tube ends to seal out moisture, while also increasing strength, and a laser-cut cross brace that reduces free span, reinforces the floor pan, and minimizes required welding during installation. All is given an industrial-grade powdercoat for long life. Welding areas are pre-masked, so no removal of powdercoat is needed before installation--a real time-saver!

Stifflers Suspension lower chassis braces dramatically increase the strength and stiffness of the front chassis area. Available for both factory and aftermarket K-members, this additional stiffness minimizes flexing to help maintain correct front suspension geometry while under load. The result is tighter steering response and more predictable handling under cornering and braking. Where applicable, Stifflers' lower chassis braces can be combined with their Spider braces (sold separately) to completely integrate the front and rear chassis sections for unprecedented car control. Features include: * Manufactured from high-strength tubing to maximize stiffness and strength while reducing weight * Design optimized using CAD/CAE software combined with real-world test data * Industrial-grade powdercoated for long life * Select models available that will work with aftermarket long tube headers * Includes hardware and rod ends (where applicable) * Depending on application, welding and drilling may be required
