D35 vs AMC20

Just curious, which is considered stronger? The AMC20 in my CJ has held up well with 33's, and am wondering about my newly aquired 88 YJ. It also has 33's.

AMC 20 with the one piece shafts can easily handle 33s. Its still not a "great" dif. But its decent, i put it in the same class as Chrysler 8.25

Your limited slip differential sucks.

Ok, so what about the D35? Stronger or weaker? They came factory with one piece axles correct? Talking in 88

The AMC 20 is generally consider a lot stronger than the 35. It has larger axle shafts.

And a large ring and pinion. I also should qualify that as the amc being approximately equal to a 29 spline 8.25. I know several who run 35s on the amc 20 and 29 spline 8.25 with rare breakage.

The d35 is by far the weaker unit.

I was afraid of that! I wanted to be sure before I go crawling it. I was told it was locked, but I haven't had a chance to pull the cover yet. Reading the factory specs in the FAQ's, mention was made to some canadian models being D44's. I found a sticker on the door bottom that said it was made in Canada. Maybe I got lucky, but it would be a first. If it's a D35, I will have to chunk it. I have a D60 (4.10) I was saving for a crawler project.
