Save the time and headache of choosing the right parts for your Ford 9 inch rear end assembly and let the experts choose a quality, hand-assembled, street-tough complete package for you at an unbeatable value.
Designed for your restoration, upgrade or custom build we start with our USA-made, NEW fabricated steel axle housing. Our housing design is pumpkin-centered and improved with two points of support on the axle tubes to reduce tube flex, instead of support only on the single weld point of traditional stamped steel housings. A greater-than-stock capacity center section holds more gear oil and runs cooler. This housing includes (8) T-bolts for the axle bearing retainer plates and (10) studs for the third member. And yet, while improving strength, we have made our axle housings on average, 2 pounds lighter than stock style housings.
Fitted with "New Big Ford"(Torino)-style bearings and a 3"O.D. axle tubes, this housing also includes forged steel axles, bearings, seals and retainers. Flanges are dual-drilled for both 5 on 4-1/2" Ford/Mopar and 5 on 4-3/4" GM wheel bolt patterns and includes two sizes of wheel studs (1/2"-20 Ford/Mopar and 7/16"-20 GM).

Our third member assemblies are precision assembled, in house by our trained technicians with new, quality components. You choose the gear ratio and we take care of the rest. We start with a new carrier housing, re-designed and constructed of reinforced nodular (ductile) iron that is far stronger than OEM ‘gray' cast iron housings. Nodular iron resists fracturing far better than traditional gray iron and is the metal of choice for the demands of high horsepower and torque. Machined surfaces and a Viton® pinion seal keep the leaks off your shop floor.
We have reinforced the rearmost pinion (pilot bearing) support and use a large "Daytona"nodular iron pinion bearing support with a spacer and shim assembly to maintain perfect pinion gear alignment and long life. The spacer/shim stack gives durability and ease of service. The larger oiling channels of the Daytona bearing support also add to long bearing life. We included a NEW, forged steel 1310-style "Short Ford" pinion yoke to round off this durable assembly.
Ring and pinion gears are built of long-wearing 8620 cold-rolled steel and assembled with Grade 9 hardware with Grade 8 carrier cap bolts. Billet steel adjuster nuts and heavy-duty keepers ensure your ring gear settings are maintained.

Our clutch-style posi differential gives you maximum traction. Based on the original limited-slip designs of the OEMs, these differential units provide the added benefits of experience over millions of miles and decades of proven reliability. A clutch-style operation means no clicking around corners and our posis feature heat-treated spider gears in a forged steel case. We've taken this posi to the next step in performance with increased clutch pressure and holding power, suiting it well for heavy-duty street car applications.
This differential has performed well in our Week to Wicked 1952 Chevy Truck, handling the job of transferring a 430 HP GM Performance LS3 to the ground.
This kit comes supplied with all necessary hardware and gaskets for a complete install.
Save time, money and be comfortable knowing you have a first-rate, hand assembled complete Ford 9 inch rearend assembly with our complete axle housing, axle and third member kit.
