Torque Solution Rear Differential Inserts: Subaru WRX / STi 2008+

Made from durable 88A durometer polyurethane, these rear differential inserts are designed to fill the voids in your Subaru's stock differential bushings. This helps to reduce unwanted movement in the driveline, especially under acceleration and braking.

When you're pushing your Impreza hard, whether on the street or the track, a solid connection between the engine, transmission, and wheels is key. These inserts stiffen up the rear differential mount, which means less flex and a more direct transfer of power. You'll notice a more responsive feel when you get on the gas or when you're slowing down, with less of that vague slop you might feel from the factory setup.

Installation involves pressing these inserts into the factory differential bushings. They're a popular choice for WRX and STI owners looking for a more connected and performance-oriented driving experience.
