I have a set of set of 4 runflats for sale for 17" rims part number 6012748. This is the beadlock and runflat for the 2 piece alpha rims. Its long been discontinued so good luck finding this. I don't feel I'll ever put this back in my truck, I'm just too lazy. $1000 for the set. I'd prefer not to shim them but I'm guessing if I had to ship it would be $50 each but I'll split the shipping cost 50/50. Item is located in San Francisco.
