10 bolt and 14 bolt

10 bolt and 14 bolt

Postby bsnowden [OP] » Dec 11 2011, 1:16am

What is the difference between a bolt 10 bolt rearend with 3.73 gear ratio and a 14 bolt rearend with 3.73 gear ratio? I know the ring gear sizes are about an inch difference but is it possible to put a 14 bolt rearend in in place of the 10 bolt?

i think the 14 bolt would be 8 lug and a 10 bolt is six so if you wanted to put a 14 bolt rear in a truck which came with a 10 your rear wheels would be 8 lug and fronts would be 6 lug also the 14 bolt is a full floater i think.

No I sure didn't aste25 I have still been trying to find a cheap rearend to put in mine i don't want to tear into that rearend.I have never messed with the rearend gears before and i'm kinda of nervous to attempt anything.A guy that lives about 40 mins north of me was going to sell me a rearend for $150 but he sold it before I could get up there.

I can understand being nervous about doing something you have never done. Think of it this way, tear into it, it may not be that big of a problem to fix. Even if you mess it up really bad, the worst that will happen is you have to find a rear end to replace it. That's where you are now, so really it's a no lose situation. I think once you take the cover off of it, you will see there is not that much to it. Of course, if it needs bearings or gears, then you would have to find someone that knows how to set one up (or you can just get another rear end).

To your question, I believe so. I have a 14 bolt rear-end on my 2005 VHO and it had 6 lugs... Chevy upgraded to the 14 bolt in 2005 on SS and High Output trucks. However, you list a 1999 truck in your profile. So I think it can/will work. A Chevy dealer or ASE mechanic would be able to tell you if the length, shock mounts, brakes, universals will all fit up...

Here's a link to some pics: http://www.drivetrain.com/parts_catalog ... rsion.html

14 Bolt cover:
Strong 10.5" ring gear and pinion (12 bolts on the ring gear)
Strong Axles - 1.5" diameter, 30-spline
Stout Housing - large 3.375" x 0.5" tubes
Easily converted to disc brakes
Common to find with 4.10 and 4.56 ratio (My VHO has 3.73 ratio)
Built in carrier preload adjusters
Cheap and Plentiful
Large brakes with good stopping power

These rear-ends were developed for 3/4 ton and 1 ton trucks initially. They found their way into GM's high performance 1/2 ton trucks

I hope this helped, :-)
