3.73's were a stock ratio in the CJ's right?

I could get them cheap used if so.

3.54 and 2.73 were stock.

Well I may go with 4.10's since I'm going to wheel it and potentially run bigger tires. By the time I buy one piece axles, new gears and carriers, would it be cheaper to go to an 8.8?

Actually, it depends on the year and engine as to what was stock for that year.

On the other hand, if want a crawler, that will pop a wheelie off the line, but will be howling at 65 mph, then go with the 4.10s.

The more I'm reading suggests 3.73's as well.

I'll go with those. I want to get good mpg. Did 3.73's come in any CJ's or wranglers that I could buy the pinion ring and carrier as a stock take out part?

Wranglers won't work. No Cj's that I'm aware of. The ring and pinions are not expensive, it's the installation if you are not qualified or don't own the proper tools. You will also need a different carrier for your AMC 20 going from 2.73's

The D30 carrier from any wrangler/cherokee/comanche etc. will fit just fine in a CJ D30 case....the gears however will not if they're from a HPD30 (which I think only came in the YJ, XJ & MJ....TJ's and ZJ's would work) . Disclaimer, the previous gear info is from the interweb so who knows how accurate it is.

And yes, CJ's came with 3.73's but they seem to be more common in the NT equipped Jeeps with an auto tranny.

I thought I was pretty specific about referencing changing the carrier for the AMC 20 NOT the D30. The 20 obviously was never available in a Wrangler. And as far as the gearset for the D30 is concerned, you just confirmed they will not work from a Wrangler. So that being said, safe to say, Wrangler is not a candidate for a donor. And BTW, there are a lot of cj diesel swaps running around getting 25-27 mpg if they are set up correctly.

Good as in good for a jeep haha. I'm shooting for 18-20mpg

Good to know. I'm on a budget, so I was seeing if anything came stock with those #'s

Thanks!

Tomorrow I'll be making some caster shims for the front axle!

If I were you and I am assuming you have another vehicle you can use. Forget about the caster shims. Park that CJ until you can put some proper springs in it. Those shackles are DANGEROUS. They can and will bend sideways and potentially roll you over! I know it's exciting that you have it running and driving now, but it's time to use your head for safety. You have proven you are very intelligent just by the fact that you pulled off this swap at such a young age. Now it's time to switch gears and think about Safety. Save up for a 2 1/2" lift. Rough country gets a bad rap because of it's harsh ride but with the weight of the diesel, I don't think it will be an issue. They are fairly inexpensive lifts. I have a Rancho 2 1/2" lift and with the weight of my SBC, it rides awesome. Slightly more money, but I highly recommend it.

Not sure what your point is here. As you bring up, the M20 didn't come in a wrangler so I didn't mention it....but if the rear gets changed so does the front (unless he was staying between 2.73 & 3.55). 3.73 and higher numerically requires a new carrier. I was just commenting on your response to answering the OP's questions about possible parts donors. A wrangler may not be a gear set candidate but if on a budget, the carrier from a YJ/XJ/MJ/ZJ will work in a CJ D30.

As for the MPG comment, it was tongue in cheek......I figured all the smilies were kind of a give away.

No I knew what ya meant no problems there

Unfortunately the Cj is the only means of transportation for me at the moment, so I'll have to keep it on the road. I'll ask a few of my buddies if they know of someone with some springs so I'm not trying to bandaid it to death with shims and huge shackles. Trust me, it's a handful to drive! I'm able to live with the ratios for now, I'm slipping the clutch more than usual, but this spring it's getting a new one anyways.

More to come!

I may have missed it, but what was the need for the walrus tusk shackles? Was it just to level the jeep? If so, I'd sacrifice aesthetics for safety and put stock shackle on the front. It'll look ridiculous but you know you won't end up on your lid.

If it was for tire clearance, well, not much you can do then.....

Hutch1200 has some 2.5" springs......free.......he's in PA but maybe you can figure something out.
