Prothane

Are the rubber bushings in your suspension worn, or do you want more precise steering and less slop? Prothane makes polyurethane bushings, engine mounts and suspension parts for cars, trucks and off-roaders. Here you’ll find individual bushings, complete kits for the whole vehicle, spring spacers and other suspension parts.

Polyurethane instead of rubber

Prothane is an American brand specialising in suspension and driveline parts made from polyurethane. The material resists oil, road salt and ozone better than ordinary rubber and deflects less under load. That means the suspension holds its geometry better when you brake, accelerate and corner. The range covers a wide selection of older and newer cars, muscle cars, pickups and Jeeps, and many parts come with grease so they are ready to install.

Prothane’s key products

Bushings for control arms, sway bars, leaf springs and steering are the core of the range. They come individually and as complete kits that cover most of the suspension in one go. Polyurethane engine and transmission mounts reduce engine movement and give a more direct feel. Prothane also makes spring isolators and spacers, bump stops and other small parts that are often overlooked during a rebuild. See each product for vehicle fitment.

Frequently asked questions

Do polyurethane bushings give a harsher ride?

Expect slightly more road feel and a little more vibration, but in return the steering becomes more precise. On daily drivers, many choose to replace the key bushings rather than all of them at once.

Do polyurethane bushings need greasing?

Yes, they should be installed with the supplied grease so they don’t squeak. Re-greasing during servicing is a good idea, especially on bushings that rotate a lot, such as sway bar bushings.
