Jeep Wrangler JK Axle Assemblies | Fusion Elite Big Tube 14 Bolt Full Float Rear Axle Assembly

Introducing the first brand new, bolt-in ready, 14 Bolt axle assembly for the Jeep Wrangler JK. If that isn't cool enough, it uses 4" diameter axle tubes, making it the strongest 14 Bolt available. Standard with 35 spline chromoly axle shafts.

100% bolt-in ready with all Wrangler JK brackets and OE quality ABS. Whether you're a weekend warrior or off-road racer, Fusion axles provide the performance you need to tackle even the most challenging obstacles. If you are looking for maximum strength and ground clearance, then look no further than the Fusion Big Tube 14 Bolt. The 14 bolt is ideal for the customer whose application needs more than a rear D60, but does not need a D80, or who prioritizes ground clearance.

Fusion axles come fully upgraded with the best components, so customers don't need to navigate a lengthy list of expensive upgrades. Need customization? No problem! We can build axles with brackets kits for popular suspension systems such as EVO, Rock Krawler, and GenRight Elite.

Fusion axle design principles: 1) Maximize performance of the axle; 2) individually maximize performance of the axle for every customer; and 3) lowest total cost of ownership.

    Lowest total cost of ownership. At Fusion we truly believe that once a customer buys an axle they should not have to spend more money on them in the future. Lifetime warranty axle shafts means that in the rare chance you have an axle shaft failure, send us a picture and we will send a replacement.
