6 lug disc to 5 lug disc - The 1947 - Present Chevrolet & GMC Truck Message Board Network

theyammieguy · 12-09-2008, 10:31 PM

I have disc up front in a 6 bolt pattern, is it as easy as buying a 5 lug rotor to do the swap? If so which rotor would I need?

d10s69c10 · 12-09-2008, 10:34 PM

72 i believe was 5 lug would be the simplest.

i got a 75 front end on mine somehow. just came home that way.

Pretty sure mine is the stock crossmember but have no idea what brand conversion kit was used.

Used the whole front crossmember on mine...its out a a 87. I used the power steering out of that truck too.

All of the 6 lug disc conversions I've ever messed with used interchangable rotors with 5 lug. Same bearings, same seals, same calipers and pads.

My 72 short bed actually has 68 model disc brake spindles from ECE. I sold the 6 lug rotors on this board and replaced them with parts store 5 lug rotors off a 73 model.

I'm the one who bought your 6 lug rotors, they've been working very well for the past couple years. My truck had a complete stock 71 5 lug suspension under it, but because I couldn't find a 5 lug rear for a reasonable price, and I wanted to run rallys anyway, I bought the rotors instead. It was a straight swap. Bearings, calipers, etc all fit the same.

70c10 · 12-17-2008, 08:12 AM

I never realized you could just use 5 lug rotors on the aftermarket dropped spindles. I thought they were designed for only 6 lug aftermarket rotors.

What all was involved with the swap? I have a 87 crossmember and rear diff coming to me from Austin.

my67chevytruck · 12-09-2008, 10:47 PM

i would think so, you could pull a rotor and take it with you to the parts store and have them mic the 6 lug vs. 5 lug, if the same inner diameter you should be able to bolt up.

if you were not several hours away, i would let you test fit some stock rotors i have in the garage.

I might head to the junkyard on saturday and take a few measurements.

Thanks for the offer.

my67chevytruck · 12-09-2008, 10:53 PM

yes 71/72 were disk brakes, just did a 72 xmember swap a couple weekends back. the only thing i would be concerned with would be the inner diameter to make sure they both use the same size bearings... good luck.

my67chevytruck · 12-10-2008, 09:02 AM

thanks TX for clarifying this . I was pretty sure they would but errored on the side of caution.

70 Suburban · 12-10-2008, 10:10 AM

I would be intrested in your six lug stuff. I have a comolaet 5 lug 72 front end

Ok, what is a comolaet front end?

Tell you what, I have a 87 front end coming from Austin. You come down to Houston and help me do the swap and you have everything you want off my old crossmember.

my67chevytruck · 12-10-2008, 07:30 PM

Pretty sure I have all the tools as well. I have air but my compressor trips my breaker when it hits around 80psi.

Only thing I don't have is an engine hoist.
