Ford 9 Inch Nodular Third Member Center Section Carrier, 3.062"

Bulletproof Foundation for Your Ford 9 Inch Build

Start your 9 Inch axle build with a strong foundation. Our all-new, redesigned Ford 9 Inch center sections are stronger than factory Ford carriers and fit into most Ford 9 Inch axle housings (car/truck/van).  Standard 3.062” differential carrier bearings fit this center section, allowing the use of 28, 31 or 33-spline axle shafts.

When it comes to strength, versatility and ease-of-service, the Ford 9 Inch is unmatched. The front-loaded third member (“pumpkin”) is easily removed for gear changes or service. Ford took a good design and improved it to handle the demands of NASCAR and NHRA drag racing in the 1960’s by introducing carriers made of nodular (ductile) iron. These “N” cases offered more strength than traditional “gray” iron and withstood higher shock loads delivered by the new, high-horsepower engines – with less gear deflection and less chance of failure. The N case was the choice of Ford’s HiPo offerings like 406 Galaxies, 427 Fairlanes, “Drag Pack” 428 Cobra Jets, and Boss 429 Mustangs.

NEW, Redesigned and Reinforced Nodular Iron Housing

While original Ford N cases are still great, they’re getting hard to find. Ordinary Ford carriers, such as casting C7AW-E shown on this page, are made from grey cast iron which is brittle. This makes them more likely to crack and subsequently fail when subjected to high loads. We’ve put decades of experience to work, correcting these deficiencies in this popular axle platform. In fact, our carrier has already been proven on both dirt and asphalt tracks across America.

Our Ford 9 Inch carrier is a NEW casting with over 4 lbs. of material added in critical areas. Extra ribbing reinforces the case and rearmost pinion support (pilot bearing). Thick, forged steel bearing caps surround the carrier bearings, all securely held in place with Grade 8 cap screws. The improvements continue with rugged billet steel adjuster nuts and heavy-duty keepers to ensure your ring gear settings are maintained. All mounting surfaces are precision machined to ensure a consistent, flat surface for a positive gasket seal (no more leaks on your shop floor). An oil fill plug is included. 

Works with OEM and Aftermarket Ford 9 Inch Axle Housings

Best of all, our nodular Ford 9 Inch carriers work with both OEM and aftermarket 9 Inch axle housings. The 3.062" carrier bearing size supports 28, 31 or 33-spline axle shafts. The carrier accepts gears up to 5.43:1 ratio without any internal clearancing (and up to 7.33:1 with some minor grinding). Speaking of gears, be sure to cap your new gear set with our nodular iron Daytona pinion bearing support. This rugged unit is cast from the same material as the carrier and features big diameter bearings, ensuring there are no weak links in your driveline combination.
