Yes the are the Genesis/Nemesis/GST reservoir shocks. I bought two complete sets off of ebay and all I use was the reservoir part. I took the buggy shocks apart and inspected the parts and cleaned them. Then I took the Matrix shock bodies filled them up with new/clean shock oil and screwed them into the reservoirs. I then unsrewed the bleed screw and compressed the shaft and bled the excess oil then retightened bleed screw. Not only do the look cool but they work awesome. [sm=thumbs_up.gif]Hope this helps
