Dynatrac Serious Performance Extreme 44/60 Axle Set for Jeep Wrangler JL
The Dynatrac Serious Performance Extreme Axle Set pairs the ProRock 44™ front axle with the ProFloat XD60™ rear axle to deliver unmatched strength, durability, and ground clearance for Jeep Wrangler JL owners running large tires and demanding extreme performance. This is the first time these two advanced axles have been offered together as a complete package, engineered to handle tires up to 40 inches with confidence.
The ProFloat XD60 rear axle delivers the strength of a full-float axle while remaining up to 100 pounds lighter than traditional full-float designs, reducing unsprung weight and improving on- and off-road driving dynamics. Up front, the ProRock 44 takes 44-class axles to a new level with 60-class internals, making it the strongest ProRock 44 ever produced for the JL platform.
