'99 4WD Ranger front diff???

What front diff is used in the '99 4WD Rangers? and what upgrades are available to beef it up?

Thanks!

IFS Dana 35.

Yep, D35, however the SLA-IFS version has a non-standard differential carrier which greatly limits your locker options (I thought the Aussie was available, but apparently the Powertrax No-Slip is the only option left that I'm aware of, TTB/Jeep D35 lockers won't fit it). The CV half-shafts aren't all that durable for serious locker use either.
Standard (low-pinion) D35 R&P gears do fit it however (deepest available being 4.88).

If you're thinking of doing any serious offroad work, I would suggest swapping of that IFS out for a D44 straight axle (do a search for SAS, or straight axle swap).

No way. . .I'm doing a prerunner so no solid axle for me. . .thinking of upgrading to a full-size truck front IFS diff upgrade.

Ahhh... (you didn't mention that in your opening post)

That would be cool if you can fit the HP 8.8" diff & half-shafts from a F-150 in there somehow. I suspect you may have to narrow the housing some though (not sure what all is needed to narrow an AL IFS housing, though it seems I've seen it done).

Thanks. . .at least I know what to look for now.
