How will I know the spring rates of the eibachs if both rates are listed as the same part number? The one sold on stage 3 is the new eibach springs with 548 spring rate?
I just bought mine today from @FordRaptorLights.com I'm assuming all retailers are the new rate because of how quickly eibach changed the rate after release due to complaints which was early-mid 2017. Surely two years later all inventory is the new 548.
