Yukon Gear Ho72 Pinion Seal.Yukon Mighty Seal

If you're working on a classic GM truck or SUV with a HO72 rear axle, this Yukon Mighty Seal is what you need to keep your differential properly lubricated. A pinion seal's job is to prevent gear oil from leaking out around the pinion shaft where it enters the differential housing, and to keep dirt and water from getting in. A leak here can quickly lead to low fluid levels, which can cause serious damage to your differential.

Yukon Mighty Seals are built using modern design and manufacturing techniques to ensure a precise fit that seals effectively and lasts for a long time. This seal is designed to fit the GM HO72 axle, a common rear end found in many Chevrolet and GMC trucks and Suburbans from the 1960s and early 1970s. Proper installation is key to its longevity, so make sure to refer to the manufacturer's instructions for the best results.
