I am getting the add a leafs and will install myself. I have a lot of mechanical experience (used to build race cars) and want to make sure doing the add a leaf properly. They go BETWEEN the bottom spring and the safety spring correct or just on the bottom.

I have a 1500 crew cab that looks like a 2wd truck because the damn thing sits so low. only 84,000 on it and when I got it new it sat this way.

How much will this affect the "stock" ride. Doing the keys and that is easy.

thanks in advance for the help.

BTW searched and looked on youtube..need better answer
