Aluminum, Increased-Capacity, Black Diff Cover for Dana 220mm

Does not fit Chevrolet Colorado or GMC Canyon rear end

Recommended: 3 quarts of Nitro Synthetic Plus Gear Lube

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. Recessed bolts completely eliminate the potential for bolt sheering when crawling over rough terrain. Aluminum can't 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.

Nitro Gear & Axle strives to provide the highest quality differential & axle components available. We take the steps necessary to ensure our parts are dependable. Our product range is continually growing to meet the needs of consumers for new ratios and Fits. At Nitro we know differentials, and know what it takes to provide you with high quality components.
