Anyone know the brand of traction bars? Any good?

I'm with Rusty Rat Rod. They can work really well if they are the correct length, and the snubbers adjusted correctly. They are not just for Chebby's and Fowds, they are for leaf spring cars period. And if you can't afford new set of SS springs, Mono Leafs, and Caltracs bars, adjustable pinion snubbers and clamps. Traction bars are the way to go if you just want to use the springs you have and eliminate wheel hop and spring wrap. They can really plant the tires into the pavement and give you good traction. I'm going to use them on my 65 Barracuda to give it that 60's look. Even a new set of traction bars will cost less than all the other devises I mentioned previously. I bought mine at a swap meet for $50 and all they needed was a new can of paint. Looks great and fits perfect.
