Flanged Housing 56in axl e flange to axle flange

The Flanged Housing 56-inch axle flange to axle flange (part number HCNK56R) is a complete rear axle housing assembly designed for heavy-duty applications requiring robust load distribution and precise alignment. This centered housing spans 56 inches between mounting flanges and arrives as a comprehensive kit that includes 31-spline axles, retainers, bearings, studs, and all associated hardware necessary for installation.

Built for applications where axle width and spline count directly affect load capacity and drivetrain efficiency, this 56-inch housing with 31-spline axles provides the structural and mechanical platform for reliable torque transmission. The inclusion of quality bearings and retention components ensures proper axle support and rotational stability under sustained operational loads. At 102.93 pounds, the assembly reflects substantial construction appropriate for vehicles or equipment requiring reinforced axle geometry. The centered flange configuration simplifies mounting alignment and accommodates standard drive shaft interfaces.

This housing assembly suits owners of heavy-duty trucks, agricultural equipment, or specialty vehicles undergoing axle replacement, restoration, or upgrade work. The complete kit design eliminates sourcing individual components separately, reducing installation complexity and ensuring all matched parts work together as engineered. Buyers can verify fitment against their specific vehicle platform and mounting configuration before purchase.

56-inch axle housings with 31-spline configuration represent a standard specification across certain commercial and heavy-duty markets. Correct identification of your original axle width and spline count is essential before ordering, as these dimensions dictate compatibility with existing drive shafts, wheels, and suspension geometry.
