I sent my 2014 OEM ES shock w/ 187,900 miles to EPM Performance in NJ for servicing as it was starting to sag and was in the highest position, 2 helmets + bags and Hard +3. They mentioned there could be issues if there were parts needed that were unavailable. Removing the shock upward was easy from the right side 'hole' once I removed the rear wheel, The shock linkage bearings looked good and I lubed everything. I removed and sent them the shock, reservoir, and box thing as one piece, as they requested. They got my shipment on a Thursday and the following Friday I got a call saying it was done, no issues. I decided to stay with the same spring. Servicing was $349 + shipping, etc was total $381. They did mention the plastic shock collar electrical connector was broken in transit, they called me once they initially opened the package. They didn't think it was a big issue. As long as it plugs in and works I'm good with that. I'll update in a few days after I've re-installed and ridden the bike. Now to get my seat back from being recovered (it has 417,000 miles from being used on two STens) at Russell and I'll be ready for 2025.
