F106 Fabricated Axle Housing
These F106 axle housings are designed and manufactured in-house for extreme-duty truck pulling and off-road applications. Each housing is built around a heavy-duty structure using a 3/8” thick faceplate and 3/16” A36 steel housing construction for maximum strength and durability.
The axle tubes are fully welded to the faceplate, housing, and internal gusseting to create a rigid, unified structure capable of handling severe loads. After welding, the faceplates are precision machined to ensure a perfectly flat mounting surface for third member installation.
F106 housings are supplied fully welded with tubes that can be cut to length and configured for custom axle builds. These housings are designed to accept IMS components including billet hubs, spools, third members, spindles, and axle shafts to create a complete axle system.
Designed, engineered, and manufactured in-house at IMS for competition, pulling, and extreme off-road applications.

Additional Info
Our 05+ Ford Super Duty Nodular Cast Inner C Set is engineered for extreme-duty off-road and competition axle builds. Designed for fabricated Dana 60 and Super Duty-based front axle systems, these inner C’s provide a strong, stable foundation for high-performance steering geometry and knuckle integration.
Manufactured from high-strength nodular cast material, these inner C’s are built to handle the abuse of rock bouncers, mud trucks, Ultra4 cars, and heavy-horsepower off-road applications. They are designed to integrate with our Super Duty knuckle systems and support precise axle alignment in custom fabricated housings.
Ideal for builders upgrading factory axle components or constructing full custom front ends, this inner C set delivers the strength and consistency required for severe-duty off-road environments.
Our Axle tube seals are designed to seal the ends of Dana 60 and 2005+ Ford Super Duty axle tubes, helping prevent dirt, mud, and debris from entering the housing while maintaining internal lubrication.
The outer steel component permanently mounts into the axle tube, while the inner aluminum housing and Seals-It seal assembly is serviceable and removable from inside the housing for easy maintenance and rebuilds.
Ideal for both factory and fabricated axle builds, these seals are commonly used in rock bouncers, mud trucks, Ultra4 vehicles, and other extreme off-road applications where contamination protection and serviceability are critical. We use Seals-It seals with all of our tube seals.
Our 05+ Ford Super Duty Unit Bearing Cups are engineered for extreme-duty fabricated axle builds and off-road competition applications. Designed to integrate 2005+ Ford Super Duty unit bearings into custom axle housings, these weld-on cups eliminate the need for traditional spindle setups while allowing for larger spline axle configurations and simplified high-strength drivetrain packaging.
Machined in-house for precision fitment and maximum durability, these unit bearing cups are ideal for rock bouncers, mud trucks, Ultra4 cars, and heavy-horsepower off-road builds where traditional hub and spindle assemblies are not suitable.
Common applications include fabricated front axle housings, spindle delete conversions, custom Dana 60 builds, and high-performance off-road racing axles.
Cups come in 3.5” and 4.0” bores. Additional sizes can be made upon request.
