This should probably be moved to the General section but....the Superior Axle and Gear Super 35 Kit is an outstanding way to go if you don't want to do a full axle swap. It will come with a Detroit locker and 30 spline shafts making your 35 stronger that a stock 44.
I will be having it installed as soon as my money tree blossoms.
course more details would help, if you are keeping close to stockish form, maybe up to 33s the super 35 kit would probably work. Personally I wouldn't spend the money on upgrading a 35, but that is just my opinion.

I like my stock 35. I figure it's the "weakest link" and stock throwing a rehabed axle in there is a less than an hour trail fix. If I strengthen it that moves my "weakest link" to a more expensive and harder to fix spot. I used to carry an a rebuilt axle with me but I have treated what I have like crap and it just keeps taking it so now I just leave it at home. To each his own. I see all the bad press on the 35 but I figure if it ain't broke why fix it.
