If you are serious about your suspension the dual rate conversion is 250$ , race tech gold kits 180$ n rebuild gotta be atleast 120$ this is my dilemma right now after u add it all up prolly be better off with after market shock I've been waiting to see a dual rate axis come around but they few and far between. Getting close to just building killer stocker. And will never buy another elka shock ever again. I blow them out every 8 months. Just my input
