ALUMINUM PERFORMANCE CASE
Our Aluminum Cases are made of 356-T6 aluminum with 7075-T6 aluminum caps and billet steel adjusters, and they feature a super strong through-bolt design to give the case increased strength and decreased ring gear deflection common in most aluminum case designs. Available in 3.062”, 3.250”, and 3.812” bore sizes; all Aluminum cases are drilled for the 3/8” stock pinion studs and 7/16” heavy-duty studs. The aluminum cases are also designed to be used with either a standard pilot bearing with snap ring retention, or a heavy duty, wider pinion bearing utilizing button head bolts for retention is available. Our Performance Cases weigh only 16 lbs., 15 lbs. lighter than our Nodular Iron Cases, are CMM checked for machining accuracy, and are supplied with all Grade 8 hardware.

NODULAR PERFORMANCE CASES
Our 9” Ford Nodular Iron cases are the toughest on the planet. Available in two bearing sizes. The 3.062” side bearing size is made for posi-traction setups or spools with fewer than 35 splines, and the 3.250” side bearing size is made for use with 35 spline and 40 spline spools. There are a number of features that make our case the right case for you. All cases are heat-treated and stress relieved before all CNC machining is completed. In addition, have forged steel caps with 5/8” bolts, machined adjusters, and are tapped for an oil filler plug.

SUPERLIGHT CASE
Lightweight. Strong. Those two words typically don’t go together when describing performance racing components. Now add the word ‘Economical’ into the mix and you’ve just described our newest nodular case. This direct replacement case is perfect for those circle track racers and street rodders concerned about saving unsprung weight without sacrificing strength. This 9” ‘Super Light’ Case weighs in at under 22 lbs! In fact, it is almost 2 lbs lighter than most OEM stock cases, but much stronger. Intended for low to medium horsepower applications (up to 600 hp), it is made from the same strong nodular material used in our hi-performance drag racing case. Utilizing 1⁄2” main cap bolts, this case is reinforced around the pilot bearing, and utilizes a 3.062” diameter carrier bearing. Save weight...save money...without sacrificing strength.

PINION SUPPORTS
We offer a lightweight, heavy-duty pinion support for all 9” Ford cases. Our pinion supports are machined from solid aluminum blanks and are set up for oversized tapered bearings for increased strength. Available for both the standard 28 spline and larger 35 pinion sizes.

The 9" Factory is a Michigan-based Manufacturing facility. We take pride in our company's ability to closely monitor quality, production, and research & development. All 9" Factory housings meet ISO 9001 standards.
