Even with all pressure off spring and using a drift pin I couldn’t get that damn shock to compress enough. So I disconnected the straps at the rails and jacked up the front of sled to get the holes aligned for bolt install. Kind of a pain but job is done. Thanks for the reply!I took all the pressure off shock spring. Compressed shock to align. The tightened spring back up. If you have the spring how u want it just count turns of retainer ring you backed it off.
