Hotchkis leaf springs sagg brand-new

The factory springs never had issues with bind or torque imposed by the pinion snubber that I have ever seen. Adjustable pinion snubbers - changing the engagement point of rotation doesn't adversely affect normal springs, so yours being tweaked under the axle perches is a sign of weakness, not acceptable or expected considering that they should be designed to be as robust or more than factory and function in unison with the remaining factory setup.
