What is Hyper-flex polyurethane?

Hyper-flex is Energy Suspension's proprietary performance polyurethane material. It's formulated to be durable, resist degradation from undercar chemicals and environmental factors, and provide a firmer suspension feel than stock rubber bushings.

What's the difference between this and stock rubber bushings?

Polyurethane bushings are much stiffer than rubber. This means they flex less under load, which leads to improved handling, better control, and a more direct connection to the road. They also tend to last longer than rubber in harsh conditions.

Does this kit include all the bushings for the suspension?

This is a master bushing set, meaning it includes a comprehensive collection of bushings for the front and rear control arms, sway bars, and rear sub-frame. It's designed to replace most of the key suspension pivot points.

Product Details

If you're looking to firm up the suspension on your 2004-2006 Pontiac GTO, this master bushing set from Energy Suspension is a solid choice. It replaces a lot of the factory rubber bushings throughout the front and rear suspension with their Hyper-flex polyurethane material. This means you'll get a more direct feel from your car's suspension, which translates to better handling and more control, especially when you're accelerating hard or braking.

Energy's Hyper-flex polyurethane is known for being tough. It holds up well against common undercar fluids like oil and coolant, and it won't break down from UV exposure or pollution. This material is designed to outlast rubber by a significant margin, offering a cost-effective way to improve your GTO's performance. This kit includes bushings for the front and rear control arms, front and rear sway bars, and the rear sub-frame, giving you a comprehensive upgrade.

Installing a full set of bushings like this can make a notable difference in how your GTO feels on the road. You'll likely notice reduced wheel hop during quick acceleration and more stable braking. It's a popular upgrade for GTO owners looking for improved suspension performance for street driving.
