When it comes to cornering, your vehicle's sway bar is an essential ingredient to good performance. However, the sway bar does not work alone. It is connected to the chassis and suspension via Cadillac STS sway bar bushings. On an OEM application these bushings are made of rubber. Over time they wear out and disintegrate, leaving the sway bar loosely attached by the bushing brackets. This causes annoying rattles, but more importantly it drastically impacts performance and safety. Here at Andy's we have a full selection of Cadillac STS sway bar bushings to replace your worn out pieces. If you are at all in doubt, we highly recommend picking up a fresh set of Cadillac STS sway bar bushings. Believe us, you won't regret it.

While replacing your Cadillac STS sway bar bushings with fresh rubber units is fine, we find the benefits of upgraded urethane bushings to be a worthwhile investment. Urethane offers just enough compliance, but is firmer than rubber so that it maintains its shape and allows the suspension components to work properly. In addition it is highly resistant to chemicals, heat and degradation, so it will likely out last your car. If you are running an oversized sway bar, many top brand companies offer a selection of urethane bushings to fit your application and provide your vehicle with the ultimate in cornering ability.

Q: Why buy new bushings? What is the benefit?
A: Many advantages can be found over your stock bushings (especially if they're old!): Urethane bushings have a higher load-bearing capacity, greater tear strength, better compression set, greater abrasion resistance, and better tolerance to greases and oils. Polyurethane is an ideal material for performance suspension bushings, motor and transmission mounts. Additional horsepower, plus size tires, lifted truck suspension or lowered canyon carving street setups all mix with normal atmospheric conditions and undercar grit and grime to stress rubber bushings beyond design limits. Polyurethane bushings are firm enough to control movement and maintain alignment in sway bars, control arms, and other stressed suspension components without the harshness or resonance associated with solid metal suspension bushings.
