Shopper Award

You asked, and we delivered again! The Fusion 60/44 Hybrid broke the mold, bringing superior strength and durability compared to anything in its class. However, we can't have a class leading front axle without having a rear axle to match. Welcome the Fusion Semi-Float 60 rear axle! Just like the Hybrid, it features the strongest semi-float housing in its class.

We truly understand the abuse that our customers put their rigs through and we design our products to endure. 3.5 inch diameter and 7/16 inch wall tubes blow the competition away.
