60-66 lift springs

im having a hard time finding a lift kit for a k10 suburban and was wondering if a lift kit for a 73-87 will fit. Thanks

You might get answers faster if you post this in the 4x4 section. Specify yr BURB you have.

Re: 60-66 lift springs

There are no lift springs specifically for a 60-66. Leafs from a 70-72 k10 are the same length, and are available in popular lifts. The difference will be the eye size and the bushing types. 66 uses all bronze bushing, and a threaded bolts on the front spring shackle. 72 uses standard rubber or poly bushings.
I converted to the newer type when I built mine.

Re: 60-66 lift springs

When you go with either '70-'72 or '73-'87 lift springs, you will also have to change the spring hangers to accommodate the springs.

That's what I did on my 61. Worked just fine.

Re: 60-66 lift springs

So does the 67-72 or 73-87 give the same amount of lift or do you need a 6 inch to gain 4 on a 60-66?

What I do know is a 4" Rancho will lift a K5 6"!

so what specifically is different? I've managed to find lift springs from Tuff Country and Procomp that are 52" long and 2.5" wide, which is the specs of whats on my 64 K10 4x4's rear...

why won't they fit?

The 60-66 4x4 uses a greaseable pin and bushing to mount the springs, the newer trucks use bolts to hold them in.
I don't believe the holes in the springs are the right size. That's why I used the springs hangers off of a square body 4x4 for the rear and my machinist buddy modified the original front hangers to accept the standard bolts to mount the front springs in my truck.

Re: 60-66 lift springs

thanks 62shortstep!

so you mean the later model spring setups have larger shaft diameter bolts, and non greasable???


why manufacturers wouldn't just build a bushing to fit our trucks rather than not sell their product at all, baffles me...

or simply sell an undrilled bushing and let the user drill out the size needed...
