differential

Hey All, Just looking for a second opinion on this one. I was recently offroad and had my axles in some water, possibly as high as the breather on the rear. To be sure, I purchased some diff oil and additive for the LSD rear. The Mopar LSD additive instructions calls for 2-5% by gear oil...

The other day I turned off traction control and did a burn out and I noticed I had to sets of tire marks left on the road. I don't have a LSD so I was wondering how this was possible. I remember on old RWD cars that some had posi-traction. Do Jeeps?

EDIT: Covers are shipping! *First to market* These are professionally welded by hand, and *CNC Machined Flat* on their mating surface after welding to ensure that any warping from heating/cooling is taken care of. Update #2: 10/10/18: Rear Diff Skids Shipping...
