5x5 to 5x4.3/4 Bolt Pattern - The 1947 - Present Chevrolet & GMC Truck Message Board Network

198plus · 06-13-2012, 11:41 PM

I'm wanting to go from 5x5 to 5x4 3/4........I have 86 spindles and have the large rotors, if I remember right they are 11.86 x 1.25. I would like to use my same calipers and spindles..... So I'm wondering if there is a rotor I could use for this swap. I don't want to re drill them. Any help would be great, thanks.

The only 4 ¾ option I’m aware of is a kit from CPP but it only goes up to 1970 spindles. If anyone ever finds a combination of bearings and 4 ¾” rotors that slide onto stock truck spindles I’m sure it would be extremely popular. So far the only 60-66 trucks I’ve ever seen personally with that pattern in front had a Mustang swap.

Call ABS Brakes in Orange, Ca. They should have them. If not, they will make what ever you want.

I investigated this a little, about a year ago. What I found was talk on some other forums of a 1970 Impala rotor that had the 4.75 bolt pattern. However I could not verify that such a rotor existed. If it did, this would fit the bill, as the Impala spindle is basically the same as a truck spindle. That might be a direction for you to search.

I am also running 4.75 bolt pattern,
I searched for a while, and couldnt find anything in stone, so I just bit the bullet and had a new set of rotors redrilled and the center hub turned down.

Some of the Impala's and Caprice rotors will work with the same bearing, but they are 11" and 1" wide. I really want to use the 11.86 and 4.75 rotors. Let me know if you think or anything. Thanks

The only thing with having them re drilled is you have to grind down the webbing inside back of the rotor, to get the new pattern in.

You would think someone would make this swap.... It's a shame I can't get the wheels I want in a 5x5.
