55.2-59 Changing rear axle lugs

[mr48chev]

Personally unless the studs aren't the correct length I can't see any wisdom in changing studs. Yes you will have different threads on the rear lugs than the front lugs and if you use chrome lug nuts you may have to buy two sets rather than use one set to have chrome nuts on both ends. Lug wrench size might be an issue but a cross bar lug wrench with both sizes solves that. Being anal to have both ends match really isn't reason enough to go to all the trouble.

The only viable reason for changing is that you have an older set of mag wheels that use the shanked nuts and washers and they only come in SAE threads.

Your main concern is having the correct taper on the lug nuts that work with the wheels you run and not the actual thread of the lug nut.

As far as the bolt circle etc. is the same, I would use a metric "guide" (easy made on a lathe) to center itat the drill, then clamp tight and redrill it, if you want to get rid of the metric studs.
