T-Case Rebuild OEM ring&pinion w/LSD
So here is my question for those of you with rebuilt transfer cases, will the OEM ring and pinion with an LSD hold up to high torque or is the upgraded ring and pinion a must? I am looking for people with first hand experience, not answers like "My friend went with Shep stage 3 because blah blah blah" I know a huge problem with the stock tcase is the bearing tolerances and gear backlash is garbage. Your thoughts....

I have a wavetrac now, my tcase was already whining when I put the wavetrac in. Do you think the wavetrac installed and a new oem ring and pinion, shimmed properly would hold up well?

Your probably right. My real dilemma was that I only put about 2,000 miles a year on the car and maybe 25 track passes if in lucky. I was trying to weigh out the cost vs. benefit. There isn't much feedback around here regarding this since most guys DD the Evo and put a lot of mileage on it.

Your yearly mileage really has no significant bearing on ring and pinion life if you drive reasonably on the street. Its your launches that are going to kill them. If you launch hard on the track, and I'm assuming you do, you will need to shell out the extra cash on the upgraded parts sooner or later. You can run what you have until something happens and risk ruining the housing and your wavetrac, or upgrade the R&P for an extra $400 and rest easy. If your anywhere over 400-450 HP its a no brainer.
