Hello all,
Long time lurker, first time poster. I recently picked up a 1998 TJ, 4.0, 5spd. I am currently running my dad's 33" tires, and they work well with my set up. My problem is, I do not understand what it means to upgrade a differential. I've been looking at getting into some heavier offroading, more rock crawling and possibly some mud bogging, and I would like to have some stronger stuff between my drivelines and wheels before a catastrophic failure. Ideally I'd like to run 35" tires, for looks and possibly for some trips down to the USA for some more technical trails.
Bottom line, I've got an aftermarket LSD in the rear (I'm assuming with the Dana 35), and the Dana 30 in the front. Can I run 35" tires on my front diff, or is there something I need to do to it? For the rear, I've heard of a 'Super 35' kit, but I don't understand what parts that all entails. If I upgrade my diffs, do the new components fit inside my current housings? I've also heard of things like regearing, chromoly shafts, and lockers (What are the options?), how would a basic all around setup look for me? I would still like to be able to drive on the highway, but I'm fine with being limited to 90kmh (56mph) or so (will I lose 5th?).
I've been looking at various forums but I haven't found anything laid out in a way that I can understand the relationship between everything Even if somebody fires a few links in the comments here that I can follow that would be awesome. Apologies if this is too broad of a topic, I'm pretty new into this whole thing and I'm not sure what's appropriate.
Thanks a bunch,
Sam (18y/o and moderately clueless)
