10"? :eek: :eek: I put a set of new regulation 5-leaf Metric Ton springs on mine, 1500# load capacity, and gained 3" only. Whoever built those springs had the arch all wrong. They came in two flavors; two thick leafs and three thin leafs (early), and one thick leaf and four thin leafs (1990+). Or did you go SOA when you installed your new springs?
