Our Torque Solution Billet Rear Differential Inserts are machined from solid 6061 billet aluminum and then anodized black for corrosion resistance. This kit makes for a much stronger 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 on throttle input, along with eliminating annoying clunking during hard shifts. Best of all smoother power transition from drivetrain to the pavement. A simple and effective install that fills the voids in the OEM mount bushing.
