- ACDelco crankshaft seal and harmonic balancer kit w/washer and bolt

I do have a few more upgrades planned before Oct when my friends and I will be in Moab. BTW PM me if you're interested in joining us in Moab, last year we had 8 suv/trucks and around 6 atv/utv's in attendance. Anyway, here is the list of future upgrades before Oct;
- Outfitter Design steering rack kit and front differential bushings
- ACDelco expansion valve kit
- ACDelco CV axle and seal (driver side). I've had a minor front differential fluid leak for over a year that I'd like to finally fix that I suspect may be fixed by replacing these parts.
