Yukon maintains two in-house quality labs to validate dimensional accuracy and metallurgical composition on every gear set. As the official Gear & Axle of the Ultra4 Racing Series and King of the Hammers off-road race, Yukon ring and pinion sets are proven performers from the street to the trail. Pair this gear set with a Yukon Master Overhaul Kit (Ford/Timken-10.5D) for a complete differential rebuild.
