Spring Rate of RoadActive Suspension Custom Leaf Spring Enhancement Kit
Question:
What is the spring rate of the extension spring on the 3000lb. kit and what is the rate for the 2000 lb. kit spring?
asked by: Todd
Expert Reply:
According to RoadActive Suspension the spring rate for the standard kit # RAS3611-S is 2,400 lbs. For the heavy duty # RAS3611-SHD it is 3,600 lbs. The heavy duty # RAS3611-SLHD is the same but only designed to fit if you have factory top overload springs on your 2016 F-250.
I did ask if that was the actual pounds per inch measurement since it seems rather high and they weren't entirely sure. I know this measurement correlates with the weight capacity of each so it is probably best to think of the kits in terms of the support added based on the capacity.
If you were using this information to try and decide between the two I would recommend getting the heavy duty version. These are adjustable, and the lowest setting on the heavy duty is equivalent to the highest setting on the standard. I would expect you to at least want that much support if you're using this for frequent towing and hauling.
