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. 

• Why Kingpin? Regardless of price or size of the axle, every ball joint wears out, and often faster on 1-ton axles due to tire size, hydro assist, and off-road use. The Fusion springless kingpin design will never wear out and incorporates a preload adjuster should a customer ever need to tighten the steering. You will never need to replace parts and they will always feel like new.
• 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. Kingpin means no ball joints to wear out and replace. 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. Included 2.5 Ton Steering provides a lifetime warranty against bending or breaking, which means you not only have the strongest steering in the industry, but also that you won't have to spend more money on steering again.
• Next generation rear 40 spline assembly. 18 months of design, engineering and testing, resulted in the industry's strongest 40 spline rear assembly. The design completed rigorous FEA testing and analysis.
