Spoke with Dale from KHC today. He's a wealth of useful technical information on Raptors, including the Gen 1 vs Gen 2 rear shocks. His recommendations for my 2011 SCREW setup: (stock rear springs, shackles, & bumpstops, with new Deavers at least a year from now), is to retain the Gen 1 rear 2.5 Fox shocks and oem shock mount until I'm ready to upgrade everything. At that time I'll put on the KHC shock mounts, Gen 2 3.0 Foxes, Deavers, new shackles, 2.5 King bumpstops & a new contact pad all at once.
