Ultra Fab Ford 9 in Rear End with Mounts, Ends, Fill, Drain, & Vent.

Ultra Fabricated housing centers are constructed from .125” alloy steel with a heavy duty .375” face plate. Triangulated design provides rigid housing tube support for more consistent and straighter launches. Internal radial gusset plates brace end of housing tube and increase overall housing stiffness. Tube insertion locations are slotted for 5” to allow complete and secure welding of the tubes to the housing. The housing is designed to provide the clearance necessary for cases with heavy duty main caps and also allowing the use of 9”, 9 1/2”, or 10” gear sets. The H1110UF housing center is designed to accept 3” OD tubing and the H1112UF is for 3 1/4”. Both housing centers come equipped with center section studs installed.

The housing is fitted with fill and drain plugs, tubed with your choice of .250” wall, 3” or 3 1/4” mild steel tubing, and choice of mounts and housing ends. While larger tubing is stronger, the mounts selection may have determined tube diameter. This configuration is the safest way to maintain the proper alignment of the housing ends. The fixturing and welding of the housing ends is always our last operation. For vehicles that will see very hard launches, there is an option to weld a back brace along the rear of the housing. It is designed to eliminate housing and tube flex that can occur under harsh conditions. An optional satin black powder coat finish is also available.
