Using more then 1 spacer

Is it safe to stack wheel spacers?

I have 1.5" spacers on my rear axle and would like another 1" at least. The spacers on there, werent cheap and I don't really want to get rid of them....
 
they are sooo expensive though, grrrr

the 1.5" ones i have cost $200 and thicker ones closer to $400...

I figured it would put to much stress on the the studs or not center right
 
heres what I have,

a 2005 chevy silverado 1500, with a 1986 rear 10 bolt axle, with 2005 chevy lug studs (6 lug)

but i need a 3" spacer (per side) with a wide center opening

those are for toyotas on that site...
 
Yeah but I cant really do that since my rear axle is custom... no one makes rims for an older chevy axle with newer style lug studs with lug centric wheels or at least i cant find any.....and they have to include a 170mm center opening

almost all the wheels you find are lug centric.

Unless you meant to say hub centric, wich is a lot more rare.
 
Im failing to see how if your wheels are lug centric and the opening in those spacers I linked are huge (as open as they can possibly be with the wheel pattern} how they wont work.
 
the problem is not the size...


the spacers i have are 6 on 5.5 with a 170mm center opening, the problem i had was getting that for an older axle with the larger lug studs from the newer chevy

i had the axle shafts milled to accept newer larger lug studs so i could use my original rims....

Trust me ive had to return many sets to get it right and the width is still not right..

When you say larger studs you mean longer? If the wheels arent hub centric what does it matter how big the center opening is? Im trying to understand your dilemma but I just dont get the issue.

If the spacers are on the outside of the drum there isnt a point in the spacer opening being a specific size. You are already past the axle register they centers the drum.

Does the wheel have some sort of taper that goes into the spacer/drum on the setup?

If the problem lies with the studs in the spacer than I can see why you're having trouble finding a reasonably priced set. Things for newer vehicles = more expensive. But couldnt you buy and older set of spacers and have a machinist knock them out to the correct size for newer studs? I'd imagine they have a bigger knurl than the old ones.
 
Those are during the build


the rim picture: the center is small on the rims and doesnt fit around the axle center and the brakes

the axle : 1986 10 bolt

lug studs: what came on 2000 series silverado (9/16- long studs)

Rims: factory aluminum 20" SSC rims with only 2" center opening

center hub on axle: 5"+ (or about 176mm)

problem: either you have a spacer that fits old chevy 1/2" lugs and wide opening or you have smaller opening apacer meant for 9/16 long studs (meant for 2000 years silverado)...Not both mixed
 
to answer your question about machining the spacer for the different studs, yes I could and have tried, no one wants to take responsibility and liability for it; ive been to multiple shops


on the 10 bolt rear axle; the axle flange (outer surface on the axle) has a center "hub" that sticks out about 1/2", my rims wont fit that, so i need a spacer with a wide opening, conversly i need the longer larger studs to go with it...Hard to find with out a big price tag
 
*BTW-- just on personal note: I will NEVER buy another one of these trucks!! Nothing but problems, parts GM cant get, and serviceability that no one knows how to do.....*

Ok I get it now. the thick aluminum flange from the newer wheels is preventing you from being able to use older style 7/16ths spacers like what I linked right?

How bout this. Buy older ones made with 7/16ths studs. Should be plenty of meat to drill and tap them out to a 9/16ths screw in wheel studs and should be plenty of meat in a 3in spacer to counter sink the Allen head into it.

Doing this with screw in wheel studs isnt too bad. You would simply buy a 9/16ths tap and corresponding drill bit. Drill them in a press and then chock the tap up in the press and turn the the press by hand to start the tap dead center.

Only dilemma is getting the heads countersunk to a nice flat surface. Machinist has to do that with a mill.
 
and thats the other problem,

some shops dont want anything to do with tampering with wheel spacers,

Sorry i suck at describing things
 
my friend did the work on my axles at his shop, but the building went into forclosure and hes out of business
