Polyurethane T-mount bushing set for the rear differential mount. Stiffen up your rear differential and keep it from banging around under hard acceleration. Helps tie down your entire rear end!
High-mileage vehicles probably have heavily worn rear t-mount bushings, which will introduce a lot of play in the rear end, and can cause you to hear an audible thump from the rear when launching. It can cause unwanted movement in the rear. Remove this movement and tighten up the feel from the rear of your car!
