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.
