Protect Your Diffs: Cheap Axle InsurancePosted in How To: Transmission Drivetrain on August 26, 2016 0) (
If you've ever had the misfortune of peeling back, cracking, mangling, blowing a hole in or otherwise damaging one or both differential covers on the trail, then you understand the worthwhile investment that is a beefy aftermarket differential cover. We've have destroyed diff covers every way you can think of. It's simply something that's an inevitable part of wheeling (and sometimes driver error).
As the tires on our rigs get bigger, we tend to hit things with our diffs a little less frequently. That's only until we get brave enough to move onto trails with bigger rocks. It’s a vicious cycle. Our ’13 Wrangler Unlimited Rubicon is far from a radical rockcrawler, but it sees plenty of trail action. With Dana 44 axles and 33-inch-tall General Grabber tires, it doesn’t have a tremendous amount of axle clearance.
While Jeep does a decent job of protecting some of the JK's more venerable pieces, the stock differential covers leave plenty to be desired. To upgrade from what would eventually be a messy trail repair, we picked up a set of Pro Series differential covers from Dynatrac. The aftermarket axle specialist is well known for its ProRock axlehousings, but Dynatrac also has a strong assortment of axle add-ons that can drastically improve your current axle set.
We spent a couple hours in the driveway knocking out our diff cover install. For the modest investment in time and money, we are more than happy at the new level of protection our JK now boast.
