Fox Body 5 Lug Conversion Kit Info
Ford Mustang 4 lug wheel options can be very limited for your 5.0L Stang and that is why we have been offering our complete Mustang 5 lug swap kit for years! Installing one of our Fox Body Mustang 5 lug conversion kits will open up a wide variety of aftermarket and factory wheels for your Stang. Not only will our complete five-lug conversion open the door to more wheel options but it also supplies you with stronger rear axles (forged one-piece design) and new brake components.

We put our years of Fox Body experience and knowledge to use and built these complete kits to help you take advantage of all the benefits of a 5 lug swap!

- To start out our 5 lug swap, support your car in the air and remove all the wheels.
- We'll begin with the front by removing the brake caliper. Pop off the dust cap. Remove the cotter pin, nut retainer, nut spacer washer and outer wheel bearing.
- Then slide your old rotor of the spindle. Go ahead and clean up all the old grease off the spindle as well as off the nut, spacer washer out of the grease cap, and the retainer.
- Wipe down the bearing races with brake cleaner. Pack the area in between the bearing races with grease and smear some grease on the bearing races. Pack your wheel bearings with your choice of wheel bearing grease. We decided to use Royal Purple!
- Install you’re inside wheel bearing followed by the new grease seal. Smear some grease on the spindle. Slide the rotor into place.
- Slide in your outer wheel bearing, followed by the spacer washer and nut. Tighten and loosen the retaining nut several times while rotating the rotor to fully see the bearings.
- Once you feel the bearings are fully seated. Tighten the nut and loosen it by one flat. Rotate the nut retainer around until you can clearly see the cotter pin hole. Install your cotter pin.
- Pack some new grease inside the bearing dust cap. Install the cap into the brake rotor. Slide your caliber back into place and bolt it down. Repeat this for the other side.
- Remove the 10 cover bolts. You will want to grab you an oil drain pan and remove the rear cover.
- Slide your drums off. Rotate your axle around to where you can access the cross pin retaining bolt. Remove the cross pin retaining bolt. Remove the cross pin.
- Slide one axle inward and remove the c clip. Do this for the other side. Remove both rear axles. Grab your new axles and the included 10 wheel studs. There are several different ways to install these wheel studs. The tried and true method is to hammer them into place. When using the stock wheel studs it doesn't take a whole lot of effort.
- If you're using aftermarket style ARP long wheel studs, you will need to enlarge the holes on the axle flange and use a hydraulic press. Slide your new axles in the housing being careful not to damage the outer oil seal. Slide 1 axle all the way inward.
- Engage the c clip and push it back out till it locks in place. Do this for the other axle. Reinstall your cross pin and the cross pin retaining bolt.
- Thoroughly clean the face of the axle housing along with the differential cover. We always recommend using one of our reusable differential gaskets. This way we will not have any excessive RTV silicone spilling out of the differential cover. Reinstall the rear differential cover.
- Tighten down all 10 bolts. Remove the fill plug from the front axle housing. On the second bottle we normally put in about half the bottle.
- Then add the bottle of Ford Racing friction modifier to the remaining half bottle of oil. Finish filling the axle. Apply some thread sealer to the fill plug and reinstall the fill plug.
- Slide your new brake drums into place. Install your new wheels and lower the car onto the ground. Of course, the perfect finishing touch to any 4 to 5 lug conversion is a new set of 5 lug wheels. We chose to go with a set of our chrome SVE Drag Wheels.
Since this kit utilizes the Fox Body spindle, Here is a list of wheels that will work with this kit without modification:
Not that you have this Fox Spindle 5 Lug conversion kit installed, adding more modern 5 lug wheels and designs is much more attainable! Keep in mind that many 94-04 wheel offerings that we sell will not fit due to center bore and grease cap fitment issues. Refer to the list that we have above with wheels that we know will fit your Fox Body Mustang!
