You are still in love with your Toyota Supra, even though it is close to being called a classic. It has not been handling well, though, and you suspect it is time to start tracking down a Supra differential to get your baby back on the road. A working differential gear is what is called a planetary gear, which means that the center of one of the gears revolves around the center of another one of the gears. It is used to allow superior handling during turns because the outer drive wheel can rotate faster than the inner drive wheel, balancing out the speeds of each wheel. When the differential is off, turning becomes more difficult and the overall handling suffers. Even something as simple as a crack in the differential cover can allow debris to damage the gears. No matter what kind of parts you need for your Supra differential, the vast inventory on eBay means that you can find everything that you need to get your sports car back into good shape so you can keep turning heads.Shop the large inventory of car and truck parts and other car and truck differentials and parts!
