Hotchkis leaf springs sagg brand-new

The original poster has never said he had wheel hop problems.
But he DID say the (not pinion) u-joint was hitting the floor. My bad, those things have to be seriously wrapped to get the u-joint into the floor. It's either new springs or something to control them. I don't believe handling is even on the table yet at this point. But I think the biggest part of the problem is it's just sitting way too low the way it's set up now.

Under VERY moderate acceleration my axle torques over my pinion snubber, and allows the u-joint to hit the driveshaft tunnel.
