Whiteline 08+ Subaru WRX Hatch / 08-09 Subaru STi Rear Diff Mount Inserts positive power kit

With anodized alloy materials and internal grease reservoirs, these Whiteline differential mount inserts are built to handle high loads and stay lubricated. They work within your original factory bushings to maintain proper pinion angles, which helps reduce initial torque loss and ensures more power gets to the wheels. This means you'll notice a more direct feel and improved gear shifts, especially when you're putting the power down.

The inserts feature a specially bonded design for optimized strength and are protected by a tough, corrosion-resistant powder coating on metal components. The synthetic elastomer formulation is resistant to oil, grease, ozone, and weathering, ensuring a long service life. This kit fits a range of Subaru models, including the 2008-2017 Impreza and 2015-2020 WRX models, and comes with extreme pressure grease and an installation guide.
