Fitment Information

• Subaru Impreza 2.5 GT (2009, 2010)
  • Fits Automatic Transmission Only

Specs & Features

• Instant Hook-Up: Replaces the sloppy factory rubber with 85a Durometer Polyurethane, drastically reducing "torque twist" so your engine's power translates directly to forward motion.
• The "Anti-Clunk" Fix: Stabilizes the Rear Differential Crossmember (specifically the forward alloy support), eliminating the annoying thud often heard during hard shifts or aggressive launches.
• Silent Strength: Features a Proprietary Polyurethane Formula engineered to absorb high-frequency vibrations, adding minimal NVH (Noise, Vibration, Harshness) compared to harsh solid mounts.
• Indestructible: Completely Unaffected by Extreme Temperatures, Oils, or Road Grime, meaning these bushings won't rot, crack, or turn to mush like OEM rubber does over time.
• Better Handling: By reducing differential movement, you improve the rear-end stability of the vehicle, making the car feel more predictable and planted in corners.

Product Description

If you drive your Subaru the way it was meant to be driven, you are probably familiar with the "slop." When you launch hard or shift aggressively, the rear differential twists violently on its soft factory mounts. This soaks up torque that should be going to your wheels and often results in a sickening "thud" noise from the back seat. The Rear Differential Crossmember Mount Bushing Kit is the cure.

By swapping those marshmallow rubber bushings for our high-grade 85a Polyurethane, you are essentially tightening the muscles of your drivetrain. The differential stays securely mounted to the subframe, ensuring that when you hit the gas, the car reacts instantly. It cleans up the throttle response and makes the rear end feel solid and connected.

The fear with polyurethane is always vibration. You don't want your teeth to rattle on the highway. This kit uses a proprietary formula that hits the "Goldilocks" zone. It is significantly stiffer than stock for performance, but it still retains enough damping character to soak up the annoying road noise. It is a quieter, longer-lasting, and higher-quality alternative that is perfect for a daily driver that sees weekend canyon runs.

This isn't just a repair part; it's a performance upgrade. Factory rubber is designed to fail; these bushings are designed to perform. If you are tired of a sloppy drivetrain and missed shifts caused by differential movement, this is the most cost-effective upgrade you can make. Bolt it in, lock it down, and feel the difference in every gear.
