Fxx Poly Rear Subframe Bushings

It is only a matter time before the OEM rubber rear subframe bushings in the Fxx platform become old and crack.  When this happens, the rear end moves around decreasing handling, making your rear end feel loose.  It is a good idea to replace the bushings with upgraded polyurethane.  Revshift poly bushings are the best in the business and made right here in the USA.  Choose three different durometers (hardness) depending on your application.

• Improves handing
• Will not wear out like OEM bushings
• Properly dampens the differential
• Prevents differential from moving / twisting
• Revshift bushing lube included
