14 bolt question

[socal chevy]

I know this has been discussed, but hey thats what forums are for right??

Im going to be installing my 14bff soon, and just found out that the 14bff is 3" narrower than my 10b thats in my truck right now... Is that true? How can I correct this? what are my options? Can I get different backspacing on the rear wheels? Are spacers safe?...Thanks!!

all GM rear axles(SRW) are that way. Your 10 bolt rear is that way, you just didn't notice. 1.5" spacers on each side are the best fix. You could get different rim backspacings but thats stupid IMO.

Isn't he refering to the spring perch placement on the 14b?

Why are different backspacings stupid? Just wondering if I missed something. I've been running 2.5 inch backspacing for a long time, with no probs. Just trying to find out if you know something I need to know too.

Stupid because you can't rotate tires. Detrimental to the axles? no. Just my opinion of it. Many thing spacers are a waste. I'd just run spacers on a street machine, or something I wanted to look good.

I thought he was saying his 14bolt is narrower than his FRONT 10 bolt. 14 bolt and rear 10 bolt are the same width. Both are 3" narrower than the front axle.

Exactly. If he got a 1 ton 14b the spring perches have to be moved out.

I got confused myself here, ok.

Yes.

You can get spacers, or retube the axle to make it 1.5" wider on each end, also would need new axles. Or get a dooley 14b I belive.

Can I get different backspacing on the rear wheels?

Yeah, but I agree with Sleddy, thats stupid

Are spacers safe?...Thanks!!

Safe enough, how often do you hear of a spacer problem? Alot of the crap with dubs and such have spacers to fit them without rubbing.

I have had 1.5" spacers on my ff14b for years, no problems. Every single time I take my tires off I bust out the torque wrench to make sure they aren't getting loose... and every single time it just "click click"s at me. Spacers are a good way to even out the front and rear. I don't like having difference width axles, I want the rear to predictably track the same as the front. A shade more width is also a good thing from a stability standpoint.

All rear GM axles are that way I think. It looks fine and it works fine. Its only a inch and a half on either side. No big deal. Its the way its been. When you get it on you will see its awsome. Just my opinion.
