Actually I utilize 1 on my straight front axled 62 ford uni truck. What a difference!!!

I got my damper "kit" from LMC in cally via the internet.

I'll tell you prior to the install when I hit any inperfections in the road the truck was all over the place. Now it is managable until I replace the original box with a R & P unit.

I think I got 50.00 into it. Try it - it IS worth the effort. Took about an hour to install.
