ok hers a ? that ive been bouncing around the old melon

Why not use d30's under a sami, There weeker!! but a sami is lighter than most all trail rigs. Is there realy going to be a problem. I plan to run 35" no bigger and a stock engine maybe a 1.6 some day. Why wont this work?



the prices on used d30's locked geared with discs are nest to nothing...

Just wondering what your opions are am I :smokin: something


CHUCK

Go for it! A new idea is always good. Why not do it? YOu might as well try it for yourself and tell us!

Can you get away with 4.88 gearing?

superior makes the 4.88's for the d30

I think the previous message asked "Will 4.88's be enough?" Those Zuk motorsl have no torque so you have to gear it way down, my 4.62's and 4.89 t-case felt ok with 33's, 35's definately would be marginal. Course now you can get a 6:1 t-case........

You can break a Toyota Birfield with BFG 35's on a Zuk.
I dunno if a D30 is stronger or not?:bounce:

You can get shafts to use 297x's (D44 ujoints) in your D30, so the only places you would be weaker than a D44 is the Ring & Pinion, and the inner shaft (27spline vs. the D44's 30 spline).

Two things,
THe Rock Ready Jeep TJ's from Skyjacker sport D30's with 38" swampers, gearing, and a 4.0L

Randy Ellis' ARCA Sami buggy things sports a D30 upfront with a D44 out back and 35's with a "stock" motor.

I don't see any problem with the D30 and in fact they can be upgraded to run Superior Axle shafts with 297X u joints (Same as a D44). So you could have the best of both worlds. Cheap, lighter (than a D44) and strong.

Hey Dana expert(s) what is the ring gear diameter in a D30, and where do the gear ratio's start? 3.50:1 or so for common junkyard units? Are there any stock R&P ratio's numerically lower than 3.5? (Like 3.0:1)

I got a reason I'm asking;)

I think I just found 5.38's for the D30......

Hmmmmm.....

I had 3:07's in my D30, now 4:88's
