Has anyone used the DK Customs Tri-Glide lift kit? I just ordered the regular lift kit, but did some extra reading on their site and saw the Tri-Glide Comfort Ride lift kit. What is the difference? Same price. Both descriptions say it mounts in place of the original rear shock bracket. Different part number. Item #: DK-TRI-LFKT and DK-TRI-CMFT-LFKT. Just the one has comfort in the description.
