Yukon Gears are computer-controlled forgings, forged out of 8620 steel, fully automated turning, single pass cut, and then vacuum heat treated. The sum of these processes is the ultimate aftermarket gear. This is a high performance quiet gear, perfect for any vehicle, stock and beyond. It will handle the rigors of big tires or high horse power.
