Part # 91604096 Condition New Brand Speedway Motors Sold Kit Details Info Looking for a budget-friendly, rock-solid foundation for your custom rear suspension? Look no further. Our fabricated steel Ford 9 inch axle housing kit including two axles for maximum durability.Fabricated with the Builder in Mind This housing is pumpkin-centered with uniform-length axle tubes, side-to-side. So mounting suspension brackets, especially on triangulated 3-link and 4-link systems, is much easier. Note that the pumpkin-centered design will offset the pinion yoke about 1" to the passenger side. Axle tubes are 3” O.D. with a 3/16” wall thickness. Heavy-wall tubes, along with a larger center section, significantly reduce distortion during welding of rear-link brackets or spring pads. Billet steel “New Big Ford” (Torino) style bearing ends are fixture-welded (3.150” O.D. bearing, with 2.50” axle flange offset). Total wheel-to-wheel mounting surface width is 58" (from hub-to-hub). The pumpkin is centered in the housing, which puts the pinion 1" offset from center, requiring different length axle shafts. This 58" rear end housing kit includes one 33" long axle and one 29-1/2" long axle that are cut to fit. The housing includes (8) T-bolts for the axle bearing retainer plates and (10) studs for the third member.Steel Axles Our axle housings deserve strong axles to drive your street machine.

Installation Tips Installation Notes: Disc brake kits may require increasing the i/d of the center hole in the rotor to match the o/d register or hub pilot on the axle flange, or reducing the diameter of the register or hub pilot on the axle to fit properly to the i/d of the rotor. When installing new axles in rearends with posi traction differentials, be sure to install the driver's side axle first to keep the splines properly aligned. Failure to do so may move the two splined gears out of alignment, and it may be difficult to install the driver's side axle properly if the passenger side axle is already installed. If installation of passenger side axle is done first it may require two people when installing the driver's side axle, with both parties rotating reach axle until splines are in line and the driver's side axle fully sides into the housing. When cutting axles to desired lengths, it is recommended that the following procedures are performed: Normal steel cutting machinery (cold saw, band saw, chop saw, etc.) Using a sleeve around the axle such as a small piece of PVC tubing - this allows: The axle to be spun in place while being cut A perimeter cut around the outer diameter assisting in keeping the cut square Avoiding the build-up of too much heat by doing a straight cut (like a knife though a stick of butter) To ensure you get the most out of your new 9 Inch components, it is recommended that you perform a proper break-in process: Use a name brand mineral-based gear oil, preferably 85w140 (Extremely high quality synthetic oils may be used once break-in process has been successfully performed) Place vehicle on jack stands and let the rearend spin while the vehicle idles - run transmission in both forward and reverse periodically throughout the process Continue to run the rearend until the pinion gets hot (place hand on bottom of the differential housing to verify this) Proper break-in allows: The ability to install new axles and hit the track the same day without worry Extended life for rearend components Keeps the quality and life of your gear oil Also available for consideration when a replacement axle bearing retainer for either of the following Ford applications may be required: Big Ford New Style Axle Housing Bearing Retainer Application # Specs Sold in Quantity Kit Finish Natural Housing Material Steel Hardware Included Yes Overall Width 58.00 Tube O.D. 3 Position Rear Rotors Included No Wheel Studs Included No Axle Splines 31 Axle Type Semi-Floating Differential Included No Cut to Fit Yes Brakes Included No Bearings Included Yes Seals Included Yes Bolt Pattern 5 on 4.5" | 4.75" Wheel Bolt Pattern (in.) 5x4.5 in. | 5x4.75 in. MFG. Part # 91604096 Reviews You arent going to beat this for the price, anywhere! Rated by Dave H. on April 27, 2021 Summary: If youve ever built a car and needed a specific width of rear differential then you know how hard they are to find, especially if youre building something that isnt typical. This rear end kit is excellent quality, priced very competitively and was perfect for my application. No searching eBay or the classifieds trying to find that rare differential that would actually fit or have one narrowed and deal with all the headache that comes along with that. If you need a 9 inch for your project why not go with a new on that meats your specifications exactly with no hassles? Pros: Good Price / Value No scrounging around or searching for used parts Perfect Yes, I recommend this product. Tech Support We're here to help before and after your purchase.
