Differential Mounts
Differential mounts secure the differential housing to the chassis or subframe and control movement under acceleration, braking, and cornering. Stock rubber mounts isolate vibration but can deflect excessively on high-power builds, causing wheel hop, inconsistent traction, and accelerated driveshaft wear. Upgraded polyurethane or billet aluminum differential mounts sharpen throttle response and improve drivetrain consistency.Popular Differential Mount UpgradesPopular upgrades include Whiteline and SuperPro adjustable polyurethane rear differential mounts for Subaru WRX and STI, BMW E46 and E9x platforms, and Mitsubishi Evo and Eclipse AWD builds. Solid billet differential mounts are common for dedicated track cars where NVH is acceptable in exchange for maximum rigidity. Adjustable mounts allow rear differential position tuning for alignment correction on lowered vehicles.Will upgraded differential mounts cause extra noise?Firmer mounts transmit more drivetrain and road noise into t...
