Custom Rear Axles

Here at Gearhead Machining, we build custom narrowed Ford 8.8 and Ford 9″ rear axles. Prices start at $750, and go up from there depending on what other services and parts need to be added to the project.  We also narrow and build GM 10bolt rears, and have the capability to do GM 12 bolt.   We will be starting to narrow Superduty/Sterling 10.25/10.5 rears, and Superduty front axles for early Bronco and Jeep applications.

Our Ford 8.8 axles we build are typically 31 spline and disk brake, but I also have drum brake setups for those who do not want to bother with proportioning valves. The 8.8 rears will come with new axle bearings and seals, as well as new parking brake shoes for disk setups, because they are a tricky job to do when the axle shafts are in.   I usually stock the most common overall width, 56 1/2″ from wheel flange to wheel flange.  62 1/2″ is another width I have available, and are a nice width for half ton trucks.

For an extra $100, I can re-drill axles and rotors. I prefer to re-drill new rotors, which are typically around $45 each, and I can locate the spring perches any width you require (I prefer the end user to locate and set pinion angle, as each custom vehicle settles differently with weight and spring geometry).  You can supply the rotors (advance autoparts online can ship right to me, and you get 15-25% off coupons on their website), or I can source them.  If you prefer drilled/slotted rotors, I suggest R1concepts. they have a variety of rotors for any application.

These disk brake axles are all setup for a parking brake, and use all oem parts you can find at the parts store if needed.

Perfect for classic Mustang, Fairlane, falcon, cougar, and any other hot rod, street rod, ratrod, classic or other project. Gear ratios available are 3.73, and 4.11.  Other factory ratios are 3.27, 3.55, but are harder to find, especially with disk brakes.   However, I can setup any gear ratio you prefer as long as they are new or good used.

Shipping not included. For an extra fee I’ll build a skid or crate and have it ready for pickup by your shipping company, or I can drop off at YRC freight for shipping, or any other location you prefer usually.  Please use their dimensional freight quote calculator for an ESTIMATE. or this link YRC Quote.

Use 60x24x20 for the skid size, and 300lbs for weight.   This gives us plenty of room to add other stuff for shipment.  Drop off at YRC freight terminal, 19446.
