Buy 8.25 HD Differential Cover (Rear) (RT20027)

The 8.25 HD Differential Cover (Rear) (RT20027) is a heavy-duty upgrade designed to protect and

reinforce the Chrysler 8.25-inch rear axle,h commonly found in various Jeep vehicles. Built for durability

and performance, this component is especially suited for off-road enthusiasts and drivers who demand extra strength from their drivetrain.

Manufactured under the RT Off-Road line by Crown hAutomotive, this differential cover is constructed

from 3/8-inch thick forged steel, making it significantly stronger than standard factory covers. This

heavy-duty construction provides superior resistance to impacts from rocks, debris, and rough terrain,

helping to prevent damage to the differential housing and internal gears.

One of the key features of the RT20027 is its reinforced ribbed design, which adds structural rigidity

and helps the cover maintain its shape under stress. These strengthening ribs reduce the risk of bending or

deformation, ensuring that the differential remains properly sealed and protected even in extreme driving conditions.

Another important design element is the raised

Another important design element is the raised fill plug location, which allows for increased oil capacity

compared to stock covers. This additional fluid helps improve lubrication and heat dissipation, contributing

to longer component life and better overall performance of the differential system.

The cover also features a machined flat mounting surface, which ensures a secure and leak-free seal

when installed. This precision machining is critical for maintaining proper lubrication levels and preventing fluid leaks that could lead to premature wear or failure. (RT Off-Road)

Finished with a durable red powder coating, the RT20027 offers excellent corrosion resistance while

also providing a distinctive, rugged appearance. The coating helps protect the cover from rust and

environmental damage, making it suitable for both on-road and off-road use.

Installation is relatively straightforward for those with mechanical experience. The cover is designed as a

direct replacement and typically includes flanged hex bolts, a recessed fill plug, and RTV sealant, allowing for a complete and secure installation.  The process generally takes about 1 to 2 hours and is considered an intermediate-level task.

The RT20027 is compatible with several Jeep models, including the Cherokee (1991–2001), Grand Cherokee (2005–2010), Liberty (2002–2012), and Commander (2006–2010) equipped with the Chrysler 8.25 rear axle

Overall, the 8.25 HD Differential Cover (Rear) (RT20027) is a robust and reliable upgrade that enhances protection, improves lubrication capacity, and extends the lifespan of differential components in demanding driving conditions.
