Season's worth of running. Springs are PAC 1359 with PAC R508 retainers. Nothing at all wrong with the springs or retainers, but simply have to be changed out as part of the freshen-up. These set up at 2.200" install height with 380 lbs of spring pressure. Will handle lift up to .950" at the valve. Spring OD is 1.520".
$250 for springs and retainers. You're basically getting the springs for free. No warranties of course.
