Where to go to shorten my rear axel? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

abadsvt · 07-21-2007, 12:27 AM

Well, I have to shorten my rear end almost 6". I knew i had to shorten it but 6" caught me way off guard. So i was hoping to get some guidance. Where should i go to get it shortened? Also what do you think it might cost? Is there anything i should make sure they do or is it a pretty simple job. Thanks ahead of time.

Why so short?

abadsvt · 07-21-2007, 03:22 AM

Well i just bought my bed and i measured it out to be 71.5" and my width of my rear end is 77.25" with my wheels and tires on.

You need to "narrow" the rear axle housing and shafts,right?Like what Currie Enterprises does?What`s up with your truck?Tell more about it.What bed do you have?What points did you measure from on truck and axles(tires)?What tires and wheels do you have?12-bolt coil rear?

PanelDeland · 07-21-2007, 10:30 AM

I would get some quotes on what it will cost.It may be cheaper to buy a narrowed rear from "Currie" or someone.

Yeah i am needing the narrow the overall width of my rear end. Well i just got my fleetside bed and i measured the inside of the bed where my tires are going to be tucking into which measured 71.5". So then i when to my rear end with rims and tires on and measured that. It came out to 77.25". That is how i came up with the 6". I bought a set of Foose nitrous wheels. I wanted the deepest offset they offered which was a 20x10 wheel with a 4.5" backspace or a 5". I don't remember exactly what it was. I have a 12bolt rear end. I had the rear axels redrilled to 5x4.75 bolt pattern to fit the wheels. I think i answered all of your questions.

I would like to stay with a 12bolt because i already have rear disc brakes and don't want to redrill the rear axels again unless that is my only option. Does anyone know if there is any cars with a 5x4.75 bolt pattern that i might be able to take the rearend off and make it work? Thanks for your help.

WOWOWOWOW. THat is a little more than i thought. I hope it is a little cheaper. I thought it would be around $400-500. That sucks.

yeah well when the meter is running and you get the custom axels bearings seals add labor for the custom jig welding the bottom line gets up there

abadsvt · 07-21-2007, 12:15 PM

Before i go and modify my rear end, do you know where i can find widths of other 12bolts for other cars? Maybe i will be able to just swap my rear end for a narrower one and maybe save a few bucks.

Thanks

Camaro 10/12 bolts from 67-79 or Nova's through 72 would be a good place to start looking.

6" does seem like alot though (3" ea side). If you're trying to ensure the outer edge of the wheel/tire clears the inner bed structure, remember it will have a visual impact.

My truck would also use a 4.5 ~ 5"BS on a 10" wheel. 3" each side would pull the wheel/tire combo in too far & give it the 'over-narrowed' look you sometimes see on custom cars. I suggest getting the bed installed & aligned on the frame & roll the wheel/tire combo underneath. Set them up so they look like what you want (spacing vs. the body panels) & measure for the proper axle width.

i am going to narrow my housing myself and from what i have seen of your work you would have no problem doing it too. just take your time and make a good jig to keep everything straight. as for the axles a friend told me they could be resplined for around 150 but i dont now for sure i thought the splined end was bigger than the shaft i have not taken them out yet so i dont know for sure. by the way i love everything you have done so far, it was your build thread that convinced me to build my own chassis. so thanks and keep up the good work!
