Once you add some basic handling mods such as lowering springs, upgraded struts, better tires, etc, it becomes increasingly important to consider upgrading your sway bars. As you improve the ability of your car to stick to the road, you will notice an increase in body roll (or sway/lean). This is where a stiffer/larger sway bar setup becomes beneficial. Sway bars work by distributing the upward/downward force of the car evenly from left to right, in an attempt to keep the car level (eliminate the heavy lean, or body roll while turning) the factory sway bars are sufficient for a factory suspension/tire setup, but once you change things out, they are no longer enough. This is where the larger diameter/stiffer sway bars come in, they will help keep all 4 tires planted firmly on the pavement, and drastically improve your cars handling ability.

Sway bar 101: This is assuming you have a properly setup front/rear spring rate and good shocks/struts...  For example, lets say you are coming into a corner fast and want to make the turn.  If the car tends to understeer (front pushes/does not turn) you will want to increase the rear sway bar stiffness.  People generally prefer oversteer (rear swings out) in a corner in a front wheel drive car because you can always accelerate out to control the amount of oversteer.  If the car oversteers a lot, then increase the front sway bar.

This is the next step stiffer bar than the GMPP rear. (18.5mm HOLLOW).

ZZP rear sway bar is 18.5mm SOLID.

Easy to install good product.

I installed this with the front one at the same time and what a difference it makes. I can now go fast on back roads and be completely comfortable with the car while doing so.

3800 Solid Rear Sway Bar

I installed this Rear Sway Bar on a '01 GP to help some in the body lean department. The car already has all new suspension, and I would like to add the ZZP Chrome Moly Trailing Arms did the best for the rear, this is just the icing. Great ride and compliments the Front Solid Sway Bar, only this one is a little more forgiving to install. Replace those old factory Sway Bar Links while you're at it. ZZP's are bigger, beefier, cheaper and w/grease fittings.

Top Quality

Fits great, adjustable rigidity, nice paint job and no more expensive than trying to find a stock replacement half the time. Installation was a breeze, except for the part when I couldn’t get it shimmied between the exhaust (it was upside down). PS: I was really surprised at the difference I felt after I installed this. I purchased the zzp rear and front sway bars. Although both were top notch, I actually noticed more of a difference installing the rear one. Great products as usual.
