Designed in conjunction with (and required by) Blowsion SXR Pro Freerider Air Darin Anderson and SL rider Joe Kenney; these ôKenney Keepersö are a must have for any hardcore surf or flat-water invert artist riding a Yamaha Super Jet Each set contains a left and right side front mount retainer and extended stainless hardware for installation Unique close tolerance design retains the front ôtop heavyö weight of the engine block from being flexed or thrown forward during flat out maneuvers or inverts Since this is a common occurrence even in flat water racing action, Blowsion designers also found them to be excellent insurance against ever having to replace those expensive engine mounts again Kit includes left and right contoured brackets and stainless mounting bolts.
