Dana 30, 44, 60, 61 and 70 Nitro Xtreme Aluminum Diff Cover


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.

What's normal operating temperature for differentials?


Here's a pic taken in a toterhome RV (Freightliner chassis) of the factory differential temp gauges. Pretty cool that semi trucks monitor those temps as standard equipment.


When this was taken the outside temps were in the 60's and the loads were fairly low on the axles. You can even see that with the rear most axle not engaged it was running a bit cooler than the drive axle. Still 160* F or so was the average and would not be an abnormal temp in a car or 4x4 after running down the highway for a couple hours straight.


This is why changing the gear oil regularly makes such a difference in the life span of your axle parts. The oil does break down from the heat and changing it frequently is absolutely the best insurance against premature wear and breakage.
