Whiteline Rear Subframe Mount Bushing for 2008-2009 Pontiac G8 Base, GT (Zeta)

For the 2008-2009 Pontiac G8 (Zeta), this rear subframe mount bushing from Whiteline locks down the rear subframe for a tighter rear end. The newest Pontiac G8 this part covers is already 17 years old, and the rubber and joints in this part of the suspension harden, crack, and loosen well before that point.

The rear subframe is the cradle that the rear suspension arms bolt to, and the car is attached to it through rubber mounts that are soft on purpose. That softness lets the subframe shift under hard cornering or acceleration, which dulls the feel of the rear end. A firmer bushing set holds the subframe in position, so the rear responds more directly to steering and throttle.

This listing covers the 2008 and 2009 model years of the Pontiac G8 on the Zeta chassis. The listing names the Base, GT versions. The kit contains 8 bushings, 4 tubes, an install guide, and grease. Installation is rated difficult, with about 4 hours of work listed. An alignment is required after installation. Other Whiteline parts we list for the Pontiac G8: Adjustable Front Sway Bar Link, Front and Rear Sway Bar Kit, and Front Steering Rack And Pinion Mount Bushing.
