I have a 2011 KZ Sportsmen Classic 16BH and those entry level TT (even the new 2015 models) doesn't come with EZ-LUBE axle or similar axle... I want to add Bearing Buddies grease system on the axle...
Bearing Buddies will work just fine on your TT. Same basic principle as the EZ Lube hubs with the added advantage of the spring loaded piston to keep a positive pressure on the bearing grease. I had them on my boat trailers and now have them on my landscape, cargo, and TT.
