Backspacing for a 4x4?

[SeventyOne]

I was looking around and using the search but couldn't come up with an answer.

What is the maximum backspacing for a wheel on a '71 4x4?

I am going to be lifting my Blazer and want to run 37's and 17x8-10 rims. Some of the wheels I like have 4.5" or even 5" of backspacing (seems like most 17s do) and I was wondering if anyone here had experience with wheels like this.

Thanks in advance.

Not positive about the 'maximum' but the norm is 4"s.

I've read here somewhere that the guys running the newer style chevy truck wheels have to run spacers.

I have H2's on my D60 without spacers, their a 17" wheel, what axle are you running?

It's the stock Dana 44 in the truck. I suppose I could get the wheels and if I have fitment issues I can run some spacers.

The maximum is when it hits! hehehe just messin..probly close to 4.5" but I have never tried to max it out so I could easily be wrong.
On that D44 I would stick to 3.5-3.75 range 4" max....test fitting is your best answer

Personnally I'd feel safer without spacers if I were driving it on the roads.

A wheel with 4"s of back spacing is close with a 12.5" wide tire on a 10" wheel, from there it all depends on what your runnin' for rubber.

Although a 17" wheel could possibley give you a little more room with the tie rod end.

I will have to keep my eyes open for 17s with less backspacing. Or just go with 15's in the backspacing range I need - but there is such less variety and style in that size wheel.

This truck will only be drivin on the road.

I have my stock Dana 44 in the front with 8 lug hubs from an '86 Suburban and I have the Sub semi-float 14 in the rear. I am running 16.5 x 10 Centerlines with 4.5" b/s. No problems. Rear is wider than stock, 8 lug hubs in the front maybe slightly?

I've got a newer 8 lug D44 on my 70 blazer and I am running 17x9 American racing vice wheels with a little over 5" of backspacing and -12mm offset with no clearance issues. I think you should be fine with whatever you choose.

I just remembered my brother has a set of 17x8s with 4.5" BS that I can test fit. I will see if I can this weekend and post the results.
