What gears to run and where to get them?? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Tink · 06-02-2004, 08:29 AM

Right now, I've got 3.08s with an unadulterated NP203. I'd like a little more low end grunt for the wheeling I do (lots of rocks)... Would 3.73s be good enough or should I get 4.10s? I'll eventually be turning at least 35s... maybe 38s. Also where is the best place to get them?

2wdBlazer · 06-02-2004, 09:18 AM

I would say 4:10 for 35's and at least 4:56 for 38's. I can tell you 3:73 + 38's =

**JIMs70GMC** · 06-02-2004, 09:34 AM

Go with the 4.56s even with 35s it's not that bad. Of course the motor is screaming at 65. Since the 38s are in your sights, go with 4.56s. I plan on running 36" TSL radials or 37" Goodyear MT/Rs w/ the 4.56s.

Now as far as where to get them is that parts or parts and installation? Parts go w/ reider racing. Parts and install come on down to Chesapeake and go to Standard Parts.

Tink · 06-02-2004, 12:07 PM

I've never done it before, but I am hoping to install them myself....
Does reider racing have a website?

**JIMs70GMC** · 06-02-2004, 12:34 PM

www.reiderracing.com

another:

www.ring-pinion.com

Does require some special tools for setting up the pinion/ring gear. The reider racing catalog has some good info.

Tink,
What rear is this for?
If its the S10 and your gona remove the carrier anyway, I have a good auborn posi that I would sell for $150.
I think it would fit your s10 and could check.
I'm not sure if there are different carriers for specific ratios or not.
If your intrested let me know.

If you're looking at doing the gears yourself check this out. http://www.fullsizechevy.com/fscu/axletech/ Its a step by step gear setup for a 10 bolt axle. You didn't specify what axles you have, but the set is pretty similar for all C-clip style axles.

I'm looking at gears for my 76 Blazer right now, but I would be quite interested in a auborn posi for my S10 too.

Let me know if it would work... Thanks!!

CEDJUNIOR, the front is a Dana 44 and the rear is a 12 bolt... thanks for the link!

DennyB · 06-03-2004, 09:06 AM

Tink,
Let me know what rear you have, gear ratio and axle spline count.
I bought this for a 91 S10 2WD so if the rear in the 4WD is the same then it should fit.
This was for S10 and camero rears.
Denny

Tink · 06-03-2004, 03:10 PM

Well, it is a 10 bolt with 3.42s, but I'll have to check spline count and what 10 bolt it is...

DennyB · 06-03-2004, 09:35 PM

If the splines match I bet that it would fit.
I could ship it to you for you to try and if not you could just ship it back.
Are you game?

Mike C · 06-03-2004, 09:44 PM

Another option for the S10 is a take out Torsen from SLP. Last I saw, they were $100. Check out the Torsen web site. I like the 4.10 in the Jimmy with the 35's. Randy's R&P, Reider Racing, and Drivetrain Warehouse have all been good for me to deal with. Better do a butt load of research if you plan on setting up your own gears. Especially the 44 front since you need to pull the side bearings everytime you make a shim change.

*1FaastC10* · 06-03-2004, 10:34 PM

4.10s, minimum. and if you're working with a 10 or 12 bolt out back, i'd seriosuly consider, rather than regearing your axles, to upgrade to a set of 3/4 ton axles. they already have decent gears in them, and you can normally pick them up for around $200 or so for a full set.

Spline count is 28... 10 bolt is 7.65. I'm pretty sure all the S10s were 28...

1FaastC10, I've been keeping my eyes open for a set of 3/4ton axles... most everything around here is the whole truck or chassis and I've already got 6 vehicles in the driveway! LOL

DennyB · 06-04-2004, 09:54 AM

I do believe thats the one I have. I will check tonight or tomorrow.
Some of the earlier S10s were 24 spline. I'm not sure when the change was made.
If you want it I will include shipping in the price.

That would be hella cool!

Let me know if it is 28 spline!

DennyB · 06-06-2004, 06:45 PM

Tink,
Heres pictures of the S10 carrier. It is 28 spline. PM me with you address and we'll work out the details.

DennyB · 06-07-2004, 04:29 PM

Also Tink,

I ran across this seller on ebay that may have some gears for you.
