Whiteline Rear Differential Positive Power Insert Kit 2005-2009 Legacy GT | Drivetrain Control Enhancement | Differential Insert Kit

Overview

The Whiteline Rear Differential Positive Power Insert Kit is a precision-engineered upgrade designed specifically for the 2005-2009 Subaru Legacy GT. This kit enhances your vehicle’s drivetrain responsiveness by reducing unwanted movement in the rear differential mounts, resulting in more direct power transfer and improved handling. Ideal for Subaru enthusiasts seeking a more confident and connected driving experience, these inserts fill the gaps in OEM bushings to stiffen the rear differential assembly, especially during aggressive acceleration and deceleration.

Built with a focus on durability and performance, Whiteline’s engineering approach ensures a direct fit with minimal installation effort. Crafted from high-quality materials, these inserts are designed to withstand demanding driving conditions, whether on the street or at the track. The result is a noticeable improvement in drivetrain control, which translates into sharper handling, reduced wheel hop, and more predictable power delivery—key benefits for Subaru owners who push their cars beyond daily driving.

IMPROVE GRIP, HANDLING & PERFORMANCE.

Cornering loads are spread more evenly across the tires delivering more grip and, frankly, that’s what it’s all about. You also get improved tire wear as your tires stay flatter and more upright. Comfort improves because your car sits flatter through bends meaning less movement inside the vehicle.
