What are True Dual Rate Coils?

MetalCloak JK Wrangler True Dual Rate™ Coils have one of the longest free length in the industry for greater articulation without sacrificing the OEM ride quality.

Without the advantage of the Dual Rate Design, the required Spring Rate would be too low and "squishy" -- just loading your Jeep up with supplies would affect ride height and quality.
