Poly Performance started out as a little mail-order 4x4 supply shop that sold joints, brackets, coilovers, and other solutions to a custom suspension builder's woes. Recently the company decided to take on the bolt-on suspension game and market its own complete kit for the JK Wrangler. It will be interesting to see what cool tricks this fabber supply shop will pull off.
