Has anyone seen this leveling kit. It makes sense to me that the rigidity of this product would be a better fit than a Poly kit. I had a poly kit on my GMC and it was very noisy and somewhat worn after 3+ years.

a link would help :?:

Why use anything other than the PRG kit? I think all the results posted here clearly show it to be the best, not only in quality but also in support from Greg.
