Yes, 10" upper and 12" lower. These are dual rate shocks as mentioned above. The problem is, the upper is too short to allow the shock to compress enough before hitting the dual rate stop and transitioning to the bottom 300 lb coil, and if we move the dual rate stop up any higher, it blocks the tender coil from extending properly at full droop. The combined overall rate of 120 lbs per inch works great however.
Simple solution will be to trim an inch or so off of the dual rate slider so it contacts the dual rate stop later in the shock stroke.
I forget what I figured out for the rear rate, I think it was 125 over 175, 10" and 12" again respectively.
Normally both springs would be the same length as the shock travel (in this case 12") and would be preloaded at full extension, but when you short stroke the shocks (more downtravel than up travel) like this, rates get tricky because the overall rate would need to be way too soft to obtain preload, and a tender coil is required to keep the springs from being slack at full extension.
