Ladder bars

I'm restoring/hotrodding a 71 camaro and I'm thinking about using ladder bars. It's going to be a daily driver and I'm using only 70's era parts. My question is; are ladder bars going to be "too much" for a daily street driver? Also I'd like to hear opinions on who makes the best replacement sheet metal.

Re: Ladder bars

Ladder bars are a drag racing only thing. If you want to use them on the street either the front of the bar where it attaches to the frame has to be able to slide fore and aft as well as twist from side to side using a heim joint in a grooved slot with a good sized grade eight bolt the way Lakewood did it back in the early seventies with their red ladder bars. The more expensive alternative is to include a slider mechanism attached to the leaf spring mount as Competition Engineering does it now with their yellow ladder bars.


This to keep the suspension from binding up as the suspension works on the street. There are no pot holes or speed bumps at a drag strip which is why drag cars use ladder bars.

In the late sixties and early seventies cars where going in the nines and eventually the high eights with just slapper bars that are very street friendly.



This ended in 1974 when Grumpy introduced the first tube chassis Pro Stock car a SBC Vega built to fit within the margins in the NHRA rule book.

Re: Ladder bars

Rob, Auto Metal Direct makes the best fitting sheet metal at this time. http://www.autometaldirect.com/categories.php As for getting traction Caltracs are the ticket today. Use the split mono leaf springs and the caltracs and a set of adjustable shocks. I have the 2 hole Caltracs for my 67 Camaro and QA1 adjustable shocks. I have read that guys are turning 8's with this set-up and a powerful engine. Look under accessories for all the shims, spacers, and new u-bolts. Check out the setup and tuning the Caltracs. http://www.bangshift.com/forum/forum...-set-up-tuning.

Thanks for the info. I have looked into Caltracs, but i decided I want to use 70's era performance parts only. Not sure whether its a restomod or a retro rod but I want it old school.
