9 Inch Ford Rear Axle Kit w/Posi 3rd Member, 54 Inch, 4.56 Ratio

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 the right price.  Stronger, Fabricated Steel Axle Housing with Forged Axles  Designed for your restoration, upgrade or custom build we start with our 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).  We finish off the axle assembly with Forged 1541 Steel Currie Enterprises axles.  Learn more about the superior design and benefits of our fabricated Ford 9 inch rearend axle housing kit.   3" O.D. axle tubes with 3/16" wall thickness.

Precision Built Third Member with Nodular Iron Carrier Housing  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.   See how our third members assemblies are an unbeatable combination of price and quality.  Precision assembly for the correct backlash, preload, and proper amount of pinion shims to ensure the correct pattern on the ring gear teeth. Nodular iron housing is stronger than OEM “gray” iron and has 4 lbs of additional reinforcement. Large bearing “Daytona” style pinion bearing supports for strength and reliability.
