cal tracks vs slapper bars

slapper bars are for Chebys. The caltrac will make it hook!! I had a 68 Roadrunner I tried using slapper bars on. could not get them to work at all. The way mopar suspension works all it wanted to do was pull the back wheels off the ground. I went to ladder bars and cured it. I have friends that use cal tracs on their valiant and it hooks almost as hard as my ladder bars. They started with slappers on the valiant and couldn't get it hooked either. I guess the advantage is they work.
