Differential Cover 86-97 Dana 30 Jeep 10-Bolt

The Differential Cover 86-97 Dana 30 Jeep 10-Bolt is an essential protective component for anyone maintaining or upgrading a classic Jeep with Dana 30 rear axle architecture. This cast-iron cover shields the differential internals from dirt, mud, water, and debris—critical protection for off-road enthusiasts and daily drivers alike. Whether you're replacing a worn original cover or installing fresh protection after differential service work, this Specialty Products Company unit delivers the OEM-fit quality you need without compromising reliability.

Engineered specifically for the Dana 30 10-bolt configuration, this cover features precision casting that ensures proper sealing against the differential housing flange. The 10-bolt design refers to the ten fastener points that secure the cover to the axle, creating a robust seal that prevents gear oil seepage and contamination ingress. Cast iron construction provides durability and heat dissipation, while the engineering allows for straightforward installation using standard fasteners—no special tools or custom fabrication required. The compact footprint (9.25 x 2.5 x 9.55 inches) and manageable 2.91-pound weight make handling and positioning straightforward during axle work.

This differential cover is ideal for Jeep owners running 1986–1997 models equipped with Dana 30 rear axles, including Wrangler YJ and earlier CJ platforms. Mechanics and DIY builders rely on this cover when performing ring-and-pinion upgrades, bearing service, or routine differential maintenance where the original cover has developed leaks or cracks. Installation pairs easily with standard differentials—simply drain fluid, remove the old cover and fasteners, clean the mating surface, and bolt the new cover into place with appropriate torque specifications. For anyone serious about axle reliability and longevity, a quality differential cover is non-negotiable protection.
