Whiteline Rear Differential Bushings – Mount In Cradle Inserts for 2008-2011 Subaru Impreza WRX (GE/GH/GR/GV)

For the 2008-2011 Subaru Impreza WRX, Whiteline makes the Rear Differential Bushings – Mount In Cradle Inserts. Whiteline”s note for this fit: Inserts: installs into voiding of original bushings, positive diff retention. It is listed for the GE/GH/GR/GV chassis. Order it as part number KDT903. You receive 4 insert bushings, 2 washers, an install guide, and grease. It goes on the rear of the vehicle.

The differential is hung from the chassis on bushings that are soft for comfort. Under hard acceleration and braking they let it rock, so power reaches the wheels a moment late and the rear end can feel loose. A firmer bushing holds the differential more steadily, which sharpens throttle response. The polyurethane used here deflects much less than the original rubber under the same load. This version is an insert design, made to fit into the voids of the original bushing instead of replacing the whole mount.

Whiteline rates the install as moderate and lists about 1.5 hours. A wheel alignment is not required. To go with it on the Impreza WRX, see Adjustable Rear Sway Bar Link, 14mm Adjustable Front Camber Bolts, and Rear Subframe Mount Bushing.
