ADS remote reservoir. So I removed rear coils both measurements 19.5 inches long each just exactly as posted on metal cloak website. So I carry recovery gear tools ,metal box with sliding drawer ,maybe 300 pounds total . Jeep sets level front to back so I added MetalCloak 4 1/2 inch springs they both measure 21.5 inches long as advertised by MC on there website I also put 2 of there shims ( washers) 1/8 inch each under the passenger spring. I netted 3/4 inch of lift in the rear , full tank fully loaded Jeep sits level left to right and a nice rake front to rear. Happy with results. Sorry it took so long to reply. All measurements were taken with no occupants in the Jeep
