Dan, you nailed it on stock Ryde AFX shock, it did not do much except take up space,I have tried KIMPEX (slight improvement) and SPI (really poor quality), might try a Walker-Evans...If your RMK has the non-rebuildable shocks, you may get a lot of improvement by replacing them. If the shocks are rebuildable, that can also give you improvement. Fox shocks are really good, but spendy. Arvin are good, Walker-Evans are hit and miss. Some folks really like them (I do), some folks have had bad luck. If your sled is a regular RMK and not a Pro, it probably has the Ryde AFX non-rebuildable ones.
