Default increasing tire clearance in the rear with shock change

besides changing the leafs in the rear end of my 70 firebird, would a shock change help in raising the rear of the car? so if i went from a shock with a 13.5 compressed length to a 14.5, would that increase the height in the back by an inch? the car already has new leafs in the back and extenders on the shocks. thanks

Spings hold the car up not shocks. So, you don't really want to use shocks to raise the rear. I do believe there are ways to do that though with a stiffer ride. Like using coil over shocks. Or using leaf spring shackle extension accessories.

Not an ideal way to raise the rear, but air shocks would do it, especially if you were only looking for a half inch or so. You will certainly "feel the road " if you went this route.

Raising the rear requires shackle extensions on a Firebird. Raising the rear may however require a longer shock. It’s not the shock doing the work though.

Raising the rear is a bandaid approach to fixing a tire run issue however. Get a couple passengers in the back and you’ll be right back to the main issue. The solution is a properly sized wheel/tire package with correct backspacing for your car.
