14 bolt rear

ok i need all my experts to chime in on this one. i've been talkin t some guys on fullsizechevy about puttin a 14 bolt rear in my truck. which is a 2004 z71 1500. some say they will bolt right up but the guys there say you have to cut the perches off and move them. i'm just wondering. does anyone HERE know if there is a direct bolt up to my truck? i have no fab skill when it comes to welding. they have all got theres outta 90 model 2500 4x4s and i asked about getting one outta a 03-06, which is my body style, and they still think ill have to modify it in some way. help me if you can.

just go measure one and measure the distance to the centerline of your leaf springs, that will tell you if it will fit. Let me know if you want the distance measured on a 1991 14 bolt, I happen to have one laying on the floor in my garage.

yeah send the digits my way... never know. might work? is it outta a 2wd?

Now that I don't know. Its a 1991 6 lug 14 bolt with the HUGE drum brake setup. Its most likely 4wd or a heavy half ton setup, maybe even a light duty 3/4 ton since my 95 diesel had a 6 bolt axle. I'll get the numbers this evening.

sweet thanx

you will need to get the u bolts for it, most likely breaks and everything else SHOULD just line right up. oh, you will also need to get a new u joint for the drive shaft to fit, its 45 bux at O'Reilly auto.

Ricky, did you use your 10 bolt axle plate on the 14 bolt? The ones under the axle that fits around the tube? My 10 bolt tube is about 1/4 smaller diameter than the 14 bolt tube. And the brakes have a different pattern where it bolts to the axle tube.

Greg, he used the plates with the 14 bolt and I'm confused on the brake pattern your talking about:confused:. To the OP, I think the rear end Greg has is what you need. I THINK (not positive) the 14 bolts of your year model are 8 lug, but the axle will fit without having to relocate the perches. I don't know that they came out with a 6 lug 14 bolt in 03-06.

DOH! This is pissing me off not knowing for sure now, I'll have to go find this out for sure.

The VHo's have a 14 bolt 6 lug and the SS's? 14 bolt, 9.5 ring gear 6 lug.

2001 4wd had a 14bolt disk brake rear axle. Looked at one at the salvage yard two weeks ago.

There you go...

Greg, i used the 14 bolt u bolts and the plates i used the 10 bolt ones, they were a little smaller but i only had one from the 14 bolt :lol: worked fine.

so optimal would be a 14 bolt rear with disck brakes right? 6 lug of course then convert it to 5 lug or buy after market axles? strange and moser make some cheap 5 lug axles... :)

I think he has 6 lug anyways, so he should just get a ss or vho 14 bolt. that would be the easiest.

Find a 454SS 14bolt rear end. Its 5x5 already. Buy a disc brake conversion kit later if you just have to have disc brakes.

Jeff has an OBS truck like ours. I'm assuming that's the one he's speaking of putting the 14 bolt into behind a V6. :lol:

hell yeah Greg my V6 is about to break the 10 bolt...lol

thought this was for a smalltown kid and his 04 z71

It was originally but it got hijacked. :lol:

oh LOL yea Jeff, find a 454 ss 14 bolt. i got mine cheap. i have my 10 bolt laying around if anyone wants it as a spare i would hook a brother up with a good deal :deal:

The spring perch spacing is 47" from center to center according to my yo-yo. :thumb:

ok thanks you. yall are funny and so i'll measure tomorrow morning. but your sayin find a SS six lug truck, like NBS, and it will work? or a 2500 NBS? and it should bolt right up.....

yo-yo is a slang term for a tape measure. A 2wd SS has a 14bolt, VHO and a few other late model trucks have the 6 bolt axle 14 bolt rears with disc brakes.

the only reason why i'm doin it is because eventually i want to be sittin on 37s with big HP and gears. so most say a 10 bolt won't hold up?

That or really step up to the plate and put 10.5" full floating axles in there. You'll need to swap to 8 bolt wheels but you'll never hurt that axle and if you do you can repair it on the trail or road without totally disassembling the whole axle.

my spring perches are more like 49" from center to center...
