Fiberglass leaf Springs?

[boomer 33]

Does anyone know if a compnay that makes fiberglass leaf springs for the 3/4 ton Yukon XL? I want the huge weight savings and want to adjust the ride at the same time. (Weight savings 70% or so)

I don't know about for 3/4 ton trucks, but I know the Astro vans have composite rear leaf springs that fit S-10's. I'd suggest doing a google search for it...However, I don't know that anybody would make something that big as you're talking a vehicle that weighs alot and has the capability to haul alot...I don't think you're going to get a weight savings of 70% as the springs would have to be really dense to live up to a 3/4 ton rating.
