I have a buddy w/ Toms Bronco Parts here and got the install for $45 lol. So I just had them install it. Plus they never did one before so all the guys were ooing and awwwing at my Trooper.

Yes you will need some LSD Additive. Its not that expensive, comes in small bottles. You just add it to your gear oil.

Ive had mine in about 3 months now, no heavy wheeling though. Enough to know the LSD does help vs an open diff, but you still get stuck <img src="/forums/images/graemlins/butwiggle.gif" alt="" />

I was second in line for the LSD BTW lol. Looks like you grabbed it!
