Traction problems

Not enough front end travel and may want to slow it down just a little bit. It appears to top out at same time the rear unloads. Maybe lower the front a little and cut the upper control arm bumpers.

Slow the video down to .25 speed and watch it.

Good rear shocks, or better ones are not a bad thing. Calverts work well, ranchos may be OK as long as the valving hasn't changed. Vikings, etc are overkill here IMO.
