I installed the second set of rear remotes on my DK40se and it was not difficult to do. The kit from Kioti is complete and includes instructions. Removing the seat was likelly the hardest part as it is heavy. Remove a cover from the first rear remote valve, install longer studs, stack new valve next to existing valve, run hard lines to rear, install new linkage and your done. No need to remove tire as described in instruction. Kit was $400 canadian, eh.
