Torque Solution Billet Rear Differential MountOur Torque Solution Billet Rear Differential Mount is machined from solid 6061 billet aluminium and then anodized black for corrosion resistance. We then install 75A durometer urethane with a billet pin to complete the mount. This combo leads to a much stronger, lighter and stiffer support for your rear differential by getting rid of unwanted drivetrain slop and flexing. This leads to giving you better feedback, sharper response, more predictability
