Why do some classics have exposed leaf springs and shackles showing below the rear bumper??? Can find any information on this? Most don't when you google but several for sale do...

 

Welcome to the forum, sorry I can't help, but if you don't get an answer soon, try asking this in the Classics Tech section. Good luck

 

Hey jgro!
Normally that's just to raise the rear end of the car, but sometimes they are used to control wheel hop by straightening the arch of the rear springs. Think of how the rear springs are mounted. If you leave the front of the rear spring in the stock location & raise (lower actually, closer to the ground) the rear of the spring, its going to jack up the rear of the car. Its also going to move the pinion angle upwards, planting the tire more firmly when you nail the gas. Sort of a poor mans traction bar per say.

There are many more, well, modern ways to fix both ride height & heel hop with de-arched springs & more advanced traction bars (slide a links) BUT sometimes the huge shackles look cool. They aren't really effective compared to more modern suspension set ups but they look cool if done right.

Hope thats some help. Others here have tons of knowledge but thats a general idea.
