Hehehe. It's called porpoising. Time for stiffer shocks man. Mine did it really really bad. But that is a good thing. Means you are getting traction. I had to get adjustables from summit. I bought a pair of 50/50 and they weren't stiff enough. The ass end does this in the same theory as axle wrap. Once it wraps up and maxs out, it untwists and causes wheel hop right ? Well, when you squat real bad, the leafs are going to max out from the down force, then slam up or unload the weight from the back tires. While yours may not slam up, the rear coming back up is taking wieght off the rear. I never lost traction, but I guess it was because of ET streets as opposed to DR's. But mine was horrid. It was bounce up and down about 3-5 times before the 60 ft. When, or if you get the shocks, you want the shocks to be stiff enough to kinda time the amount of time it takes you to get out of the hole, with out maxing out the leafs, or even moving at all. Good Luck
How much preload did you have to put in to stop the hop ?
