Hotchkis leaf springs sagg brand-new

First...These guys are right, those shackles gotta go!Those are the ill ticket for handling, I'm betting, too. Nothing to keep them from 'parallelogramming'.

Second, the spring ends on those Hotchkiss springs look, I dunno, wrong.
Like, how they make a saucer-hook bend instead of just being rolled up n' over the bushing. It just "seems" weak to me.
Third, if it's been a month, that's on you. There's a million and one leaf spring shops on this planet. They haven't sold you anything special. You could have de-arched some MP springs, or even stockers, and been dollars and miles ahead.

The adage holds true: Just because they make it for your car doesn't mean you should buy it for your car.
