Differential Bushings for Street, Track & Off-Road

Differential Bushings for Street, Track & Off-Road

Differential bushings mount the differential housing to the subframe or chassis, isolating vibration and controlling axle movement under acceleration and cornering. Worn rubber bushings allow excess axle wrap and wheel hop, especially on higher-power builds. Upgraded polyurethane or solid aluminum bushings restore precision and reduce drivetrain slop.

Popular Differential Bushing Types

Top choices include polyurethane differential mount bushings for Subaru, Nissan, and BMW platforms, solid aluminum rear diff bushings for drift and track builds, and Whiteline and SuperPro adjustable differential bushings for camber and alignment correction on lowered vehicles. Many kits include grease fittings to extend service life.

Will upgraded differential bushings increase cabin noise?

Firmer polyurethane bushings can transmit slightly more drivetrain noise into the cabin compared to OEM rubber, though modern formulations from Whiteline and Energy Suspension minimize this. Solid aluminum or delrin bushings are best suited for race or track applications where NVH is a secondary concern.

How do differential bushings affect alignment?

Adjustable rear differential bushings allow you to dial in rear toe and camber settings that are especially useful on lowered or widebody vehicles. They are a common upgrade for anyone chasing consistent tire wear and balanced handling on road or track.
