GMPP Rear Sway Bar

When you enter corners, does your W-Body feel more like a snow plow than a performance car? It's the thin and weak sway bars on your car! This plowing is caused by excessive body roll that loads the outside tires which creates under-steer, sloppy handling and most of all a dangerous situation if you ever need to make any sudden maneuvers. The GM performance parts sway bars can take care of this. The 18mm solid rear is thicker and stronger than OEM sway bar.

Rear sway bar does not come with endlinks/stabilizer bars.

GMPP sway bar

Install went smoothly. Definitely a noticeable difference in body roll. I have the GMPP front sway bar on my 06 GT supercharged using the 97-03 LCAs and coupled with the rear GMPP it made a huge difference. The car feels much more planted in turns now.

Cornering is much smoother, doesn't feel like I'm diving a boat now! East install and quality products. Thanks ZZP. Awesome products, awesome service.

Nice upgrade from stock OEM bar.

I should have replaced this bar first before upgrading the front sway bar on my '04 GTP. Now that I've installed these my suspension is balanced again. But a little firmer. Great bar. It's an OEM bar but mine came with the skinnier version.
