As far as I know they should be the same the 51 champ and commander are both 5 lug but the 50 champion is 4 lug but that was the last year of the 4 lug as far as I know
ALL...53 and newer Studebakers (cars) are 5 lug. 4-1/2" x 5 pattern. The model and or engine/transmission combination do not make a difference. Many do...have different brake drum "diameters", that's just additional information since you didn't ask that question. Mike
There are some models of the post war Big Studebaker (Land Cruiser...’48 to ‘50 ....and maybe Commander) that had 5 lug 5” bolt circle. Not common now, but does exist. Otherwise I agree with what has been posted. Ray
Mike and Ray, thanks for the replies. I have a friend who is in the process of a long distance purchase of a 53 coupe and didn't know the exact model, it will require tires and wheels for transport.
Are they left and right handed lug nuts or are they lug bolts ? Something to think about, I honestly don't remember what it was when we dismantled a 57 last year.
They have lug nuts.......I believe they are all right hand thread...I can confirm that and thread size tomorrow...I have a couple of '54s at the shop.
There are both left hand and right hand threads on those Stude studs. The Champions (I have a 53 Champ coupe) were the weak sister with a Dana 27 rear axle instead of the stouter Dana 44 unit, the trans is less robust and the brakes are smaller than the Commanders. I resolved that issue by buying a 58 and 59 Hawk, both v8 cars to get a heavier frame/brakes/differential etc. Unless the car has been stored in a desert hideaway you will get to be a close friend of Studebaker International and Classic Enterprises. Join the Studebaker Drivers Club also, sort of like a smaller Jalopy Journal for Studebaker nuts.
