Torque Solution TS-RDM-350 Solid Polyurethane Rear Differential Mount Bushing Set

The Torque Solution TS-RDM-350 is a solid polyurethane rear differential mount bushing set engineered to replace the soft, failure-prone OEM rubber units. Stock differential bushings are notorious for deteriorating, cracking, and tearing over time — a problem that accelerates under hard driving or racing conditions. By upgrading to these firmer polyurethane bushings, drivetrain slop and unwanted flex are eliminated, directing power where it belongs: to the tires.

The result is sharper throttle response, more predictable handling under acceleration, and the elimination of that characteristic clunking noise during aggressive shifts. Rated at 75A durometer, these bushings strike the ideal balance between firmness and street drivability. Torque Solution has torture-tested this design at over 1,000 HP and into the 8-second elapsed time range, making it a proven choice for both street and strip applications.

Key Features:

• Solid polyurethane construction — significantly firmer than OEM rubber units
• Eliminates differential clunk during hard shifting
• Reduces wheel hop and traction loss
• Improves 60-foot times and elapsed times (e.t.)
• 75A durometer rating for optimal stiffness and durability
• Tested at 1,000+ HP and 8-second e.t. conditions
• Limited lifetime warranty
• Made in the USA

A direct bolt-in upgrade over OEM components, the TS-RDM-350 is an essential drivetrain improvement for performance-oriented builds seeking improved rear-end stability and more consistent power delivery.
