Great cover but....

Reviewed By Robert L (CLOVIS, CA) Reviewed for a 2003 GMC Sierra —9/17/2014 12:12 AM

The cover is very well built and is beautiful to look at. But it's not with out is faults. First of all, unlike the G2 it doesn't not come with a gasket not is it much larger than the stock cover it replaces. I bought the cover thinking I would increase the fluid capacity and have the rear end run cooler. It might be slightly larger but not as big as the G2, nor does it have cooling fins to help with temp control. I'm towing a toy hauler and temp is the main concern. I also had leaking problems.

If you're thinking about replacing your truck's differential cover but undicided as I was my recomendation's go for it you'll be very happy with the final result, this aFe cover not only gives your truck a great look but it also helps with cooler differential performace by adding the extra quart of lube and internal & external fins, the large oil level sight & calibration plug are excellent time & work saving features, the o-ring versus gasket is also great, overall this is an excellent product,all stainless steel allen head bolts & washers included as well as RTV Silicone tube & strap to separate spare tire from cover if needed, perfect fitment fairly easy installation with proper tools.Thanks AutoAnything for your service and products.

G2 Axle & Gear Differential Covers Reviews


G2 differential cover (without dipstick)

Reviewed By Andrew F (Lancaster, NY) Reviewed for a 2009 Chevy Silverado —4/9/2015 5:50 PM

Overall very good, easy install, and look great. The only confusion was how much oil to add as the fill plug is higher than the stock cover. This cover seemed to let me add an extra quart while still having a similar oil level as factory. Not that it was a bad thing, just made it confusing whether I added not enough or too much.
