Crossmember Information:

This unique single tube design adds stiffness and strength far beyond that of the OEM versions while offering versatility like no other. Simply slide the mounting sleeves and reposition the spacers to cover automatic (TH-350 / Powerglide) applications. The crossmember is engineered to work with OEM and aftermarket transmission mounts; all while maintaining your current pinion angle. Low deflection polyurethane bushings are used in the mounts to dampen driveline vibrations and noise. For racing applications the polyurethane bushings can be replaced with optional solid bushings.

Single tube design for maximum stiffness without excess weight.
Engineered to maintain pinion angle when using either OEM or aftermarket transmission mounts
Supplied with polyurethane bushings or can be replaced with solid mounting bushing for racing applications.
Allows more exhaust clearance than OEM style.

Transmission Mount Information:

Polyurethane Transmission Mount - GM

A true performance application component for cars, trucks, hot rods. For racing / competition, yet popularly used for street vehicles when more horsepower is added. Soft running enough to absorb vibrations for street use yet rugged for racing use. Helps control torque on high performance vehicles. Maintains proper drive shaft angle to help prevent early wear and unexpected power train damage.

Replaces the original, short lived and typically too-soft rubber mounts and outdates those hard-running metal transmission mounts. Resistant to under vehicle fluid oils, coolants and road contaminants. Made of Energy’s Hyper-Flex(TM) performance polyurethane and heavy duty hardware – for added durability.
