BMW E46 80A Polyurethane Rear Subframe & Differential Mount Bushing Kit – Reinforced Drivetrain Stability Upgrade - Replaces OE Part No. 33316770781 & 33176751808

Upgrade one of the most failure-prone and movement-prone areas of your E46 drivetrain with this complete 80A Polyurethane Rear Subframe and Differential Mount Bushing Kit in red. Designed for drivers who want a tighter, more planted rear end without going to an overly harsh race-only setup, this full kit helps reduce unwanted subframe movement, improve differential stability, and restore a much more controlled feel under acceleration, cornering, and shifting.

As the factory rubber bushings age, they begin to soften, crack, and deflect far more than they should. That excess movement can lead to a loose rear-end feel, sloppy drivetrain response, inconsistent handling, and added stress on surrounding mounting points. This upgraded polyurethane kit is designed to replace those worn-out rubber components with a much firmer and more durable material that better controls movement while still being usable for street-driven cars.

The 80A durometer offers a strong balance between performance and livability. It is noticeably firmer than stock, giving the rear of the car a more connected and confidence-inspiring feel, but it is still better suited for enthusiasts who want a performance upgrade without jumping straight to an overly harsh solid mount setup. The red polyurethane finish also adds a more performance-oriented look for those who care about the details underneath the car.

Because this is a full kit covering both the rear subframe bushings and differential mount bushings, it is an ideal solution for E46 owners looking to refresh the rear suspension and drivetrain mounting system all at once. Whether your goal is sharper handling, better power transfer, reduced rear-end slop, or simply replacing tired factory bushings with something stronger, this kit delivers a major improvement in both feel and long-term durability.

Key Features:

• Full Rear-End Bushing Upgrade Kit: Includes both rear subframe bushings and differential mount bushings for a more complete drivetrain and chassis refresh.
• 80A Polyurethane Construction: Firmer than factory rubber for reduced deflection, improved stability, and a more connected driving feel.
• Red Performance Finish: Finished in red polyurethane for a more aggressive, enthusiast-focused appearance.
• Improved Rear-End Control: Helps reduce excess subframe and differential movement during acceleration, shifting, and cornering.
• Reinforced Drivetrain Stability: Gives the rear of the car a tighter, more planted, and more confidence-inspiring feel under load.
• Longer-Lasting Than Rubber: More resistant to wear, cracking, and deterioration than aging factory-style rubber bushings.
• Performance and Street Balance: 80A durometer offers a strong middle ground for enthusiasts who want sharper response without an extreme race-only setup.
