Ford 9" Axle Housing

This USA fabricated Ford 9" housing is made in 1 length, 72" long, so you have plenty of room to make what ever style axle you want.

Our fabricated Ford 9" housing comes standard with 3/8" thick faceplate machined flat and drilled for third member hardware AFTER welding to ensure a perfectly flat mounting surface and exact hole location. The outer shell is made from 1/4" thick steel with 12 individual bends which is done this way to reinforce each other. We also weld an additional 3/16" armor on high impact areas of the center section. These axle housings allow the fitment of a 10" ring gear for ford 9" and have 1/4" thick internal gusseting to tie the whole thing together for maximum strength and durability.

EVERY component is welded to at least 3 other components. The axle tubes are 3.5"x 3/8" wall structural DOM which offer the perfect balance between strength, toughness, weight and ground clearance. You wont be denting these axle tubes! The tube keys into the face plate and has gusseting within the center section so it is completely supported on all sides.

We send our standard differential cover weld in fill plug/ drain plug however an over sized fill/inspection port can be substitued which includes a knurled finish plug for quick and tool-less removal. Our housings are all hand made in the USA by our team of highly skilled professional fabricators. No robots, no imports, no gimmicks.

Best ford 9" out there
John C (Denver CO) | August 8th, 2023
I've built and wheeled a few different company's fabricated axle housings and this is the best one i've ever used. The craftsmanship on this is really impressive, it has to be bullet proof with how thick it is, it's machined on the face so the third member case seals up nicely to it. I wanna put one in a muscle car now!

Well pleased with this axle housing. Theres no denying the strength, thickness, and durability of this axle. It stands out against the rest and its easy to identify with its Ruffstuff logo.

High quality for half the price

I have used other brand axle housings and the RuffStuff housing are comparible if not superior to the quality of others at half the cost.
