Differential Cover Gaskets & Seals

Prevent gear oil leaks, maintain proper fluid levels, and protect your ring and pinion gears with high-performance and OEM differential cover gaskets. Whether you're servicing a daily driver, prepping a heavy-duty diesel truck for towing, maintaining an off-road 4x4, or building a dedicated track car, a clean seal between your differential housing and diff cover is essential to keep contaminants out and gear oil in.

Eliminate messy RTV silicone gasket makers with reusable steel-core elastomeric diff gaskets designed for quick, leak-free installation and easy cover removal during routine gear oil services. We stock precision-cut gaskets for virtually every solid axle and independent rear suspension (IRS) housing—including popular setups like Dana 30, Dana 44, Dana 60, Ford 8.8, Ford 9-Inch, GM 10-Bolt, 12-Bolt, Corporate 14-Bolt, Chrysler 10.5/11.5, and AAM rear ends.
