Calvert set up pictures

If I was using a truck Dana without provisions for a pinion snubber and on a budget
like yourself. My approach to control differential wind up would be some home made
traction bars.
The way I see it you can make them a couple different ways.
Copy the cal tracks.
Build some slapper bars.
I would be inclined to go the slapper bar route myself since I am old and more familiar with this. The cal trac system looks so weak or bendable to me?
The thing that gives the slapper bars a bad rap with the Mopar crowd is the fact they are sold as universals. If the snubber doesn't hit the forward spring eye directly it becomes more of a spring bender than a spring controller.
So if you built these the correct length and gave the snubbers a 1/2" or less before loading
you would have a true working bar rather than the pretend street bars we all remember.
Take a lesson from the SS springs also. Add a second main leaf to your spring packs that
stops directly under the front eye bolt. Add clamps on front segments to make them work as a
solid bar. Make sure your shocks are long enough not to unload the tires when the body lifts.
Shouldn't cost much and will get the job done.
Don't get me wrong I like the SS springs but they are meant to work with a snubber and
are not cheap. Used ones are usually weakened or bent. At least the ones I take off have been.
