Toughening up your Wrangler JL so that it can take the fiercest rock-crawling challenges in stride and come out on top is helped along by superior 2018 Wrangler drivetrain components – including 2018 Wrangler axles & hubs. Front axle shafts and rear axle shafts by Mammoth, Dana Spicer, Yukon Gear, and others provide the thick, heat-treated chromoly (chromium-molybdenum steel) construction that can withstand the powerful torquing forces generated by big aftermarket tires and/or heavy rock-crawling action. These resilient axles – often black oxide coated to resist rusting – won’t snap like factory axles will under these loads, but bounce back dependably, ready for more. 2018 Wrangler JL hubs & bearings offer a way to rebuild bearings when they break, wear out, or start to leak – making them stronger and better sealed than they were before.
