The Differential Cover for 86-90 Dana 35 10-Bolt Rear is a critical component for any mechanic or enthusiast maintaining or modifying a vehicle equipped with this classic rear axle assembly. This cover serves as the primary seal between your differential housing and the external environment, protecting the internal gears and bearings from contamination while containing vital gear oil. Whether you're performing routine maintenance, upgrading to a limited-slip differential, or rebuilding your rear end, a quality replacement cover ensures proper operation and prevents costly internal damage from moisture and debris intrusion.

Manufactured by Specialty Products Company, this differential cover is engineered to OEM specifications for the Dana 35 rear axle, a workhorse platform found in millions of light-duty trucks and SUVs from the mid-1980s through early 1990s. The cover design provides a secure bolted interface that creates a gasket seal against the differential housing, distributing clamping force evenly to prevent leaks under both highway cruising and aggressive off-road conditions. Weighing just 3.3 pounds with compact dimensions of 9.5 x 3 x 11 inches, this casting maintains the stock appearance and functionality while offering the durability required for heavy-duty service or performance applications where differential temperatures and pressures increase.

This differential cover is essential for anyone with a 1986–1990 model year vehicle running a Dana 35 10-bolt rear axle, including classic Jeep Cherokee, Wrangler, and Comanche models, as well as Ford and Dodge trucks of that generation. Installation is straightforward—remove the factory cover, clean the mating surface thoroughly, install a new gasket or sealant, and secure with the appropriate bolt pattern. Whether you're rebuilding after a seal failure, upgrading internals, or simply replacing a damaged factory cover, this Specialty Products Company unit ensures reliable containment and long-term protection for your differential investment.
