Your differential is put under tremendous stress every time you step on the gas pedal. If your factory GMC Envoy differential bushings are old and worn out this can cause your diff to shift drastically and create a host of problems from vibrations to driveshaft binding. Replacement GMC Envoy differential bushings are an easy way to fix these issues. Here at Andy's Auto Sport we have an excellent selection of GMC Envoy differential bushings for you to choose from. Whether you want OEM replacements or performance upgrades, you are sure to find the perfect bushings for your application in our extensive collection.

Most OEM bushings are made of rubber. While rubber is good when new, over time it degrades from fatigue and exposure to chemicals and heat. In addition rubber may not be strong enough to hold up to high performance applications. If you are building a car for the track or other performance driving it is a good idea to step up to polyurethane GMC Envoy differential bushings. Polyurethane has improved strength to keep your diff held securely in place even in the most strenuous conditions. This is a cheap modification that will really improve the reliability of your machine.

Q: What are differential bushings? Why buy them?
A: Your differential is what takes the engine power and delivers it to the wheels to propel your vehicle forward. It is held in place by bushings whose job it is to firmly keep things located while allowing for some compliance from bumps and road abnormalities. OEM differential bushings are usually made of soft rubber that deflects a lot and degrades and wears out over time. Aftermarket performance differential bushings are made of superior materials that last significantly longer than rubber, are resistant to heat and chemicals, and do a better job of firmly holding the differential in place. This means superior handling, improved traction, and reduced maintenance costs. These improved bushings will also help to reduce the wear and tear on expensive components such as your driveshaft and transmission. As a fairly low cost item, these bushings are a great investment.
