Product Details

Sway bars transmit cornering forces from the outside wheels to the inside wheels, helping to keep the vehicle flat during cornering. This in turn reduces body roll and improves the driver's cornering confidence. OEM rubber sway bar bushings are designed with comfort in mind, allowing the sway bar to articulate while permitting additional movement, leading to less-than-ideal bar retention and causes unnecessary body roll.

Powerflex polyurethane sway bar bushings are firmer than factory rubber bushings, reducing body roll and keeping sway bars in check. Polyurethane bushings won't slop around like OEM bushings, allowing sway bars to function at their fullest potential.

Powerflex is the number one selling suspension bushing manufacturer in Europe. Their experience with polyurethane bushing material and state-of-the art manufacturing techniques allows them to produce premium performance bushings, made to exact-fit standards. Powerflex performance polyurethane bushings are built to last longer than OEM rubber bushings, while improving performance and allowing for a more engaging driving experience.

Use of Powerflex Copper Grease PCG1 is recommended for ease of installation. Periodic reapplication is recommended to extend squeak-free service life of bushings.

Powerflex street bushings are ideal for street driven vehicles and those that see occasional autocross or track time. Need bushings for a dedicated track car? Powerflex Black Series bushings are the ultimate in track and race bushings. Featuring 95A durometer polyurethane, Black Series bushings are 25% stiffer than street bushings.

Powerflex is proud to offer a lifetime warranty to the original purchaser on all products.
