Nitro Aluminum differential covers are extremely thick and have been thoroughly tested in Moab, King of Hammers, and numerous other locations, proving they will handle the rocks, roots, stumps, and anything else you can throw at them. Finned aluminum dissipates heat faster than steel reducing the operating temperature inside your differential and extending the life of your components. Aluminum cannot rust and a Nitro aluminum differential cover will keep your undercarriage looking great all year round. Our wide selection of available covers makes it possible to equip both the front and rear differentials with Nitro covers on many vehicles.
