Synergy Suspension’s limit strap end tabs are made from heat-treated 4130 chromoly steel to provide the highest strength possible. The straps themselves are four layers thick. Limit straps are designed to stretch when stressed instead of stopping things cold. This stretching action reduces strain on the chassis and the limit strap mounts them selves. Synergy limit straps are available in 1-inch increments in lengths from 8 to 40 inches.
