One of the components of your car that suffers silently with age is the rubber in the suspension bushings. Over time, they break down and allow more movement of the control arms. This makes your handling sloppy and makes the car feel old.
This SuperPro polyurethane bushing set replaces just about every piece of rubber in the suspension, plus the differential bushings. Poly bushings move differently than rubber ones, allowing less deflection and no pre-loading. This means more precise and consistent handling, with a slight increase in sharp impacts.
While it might seem that all poly bushings are the same, that's not true. Our SuperPro bushings use a proprietary polyurethane mix that allows for more precise control with little (if any) NVH (noise, vibration, harshness) increases. They also have details that allow the bushings to retain grease, eliminating noise. This means they won't squeak, ever, and require no maintenance (as long as you use the included grease). How confident are we of this? These include a lifetime warranty against squeaking. Of course, that lifetime warranty includes any failure as well, and there are no disqualifications for track / competition or off-road (!) use.
Includes new bushings for the control arms (all but the rear upper control arm bushings) and the differential bushings. Bear in mind that the diff bushings will increase the NVH (noise, vibration, harshness) by a noticeable amount - they could be okay or terrible, depending on your tolerance level. The NVH change due to the suspension bushings is much smaller.
Installation is not trivial, be sure you know what you're in for. While regular maintenance with fresh lubricant is required for cheaper poly bushings (which is why we've historically preferred rubber bushings for anything with a license plate), that's not the case with the SuperPro bushings.
