I have a 2011 downtown , if you have a later model let us know what your manual says the size of the sliders are,. my manual says roller OD is 19.92 to 20.08 service limit is 20 width is 12 mm. with 8 sliders in a set,. now I am trying 22110-lge5-eoo drive plate, and a lge5-eoo ramp plate,. it is from a GT 300 people ,. it has a longer ramp and 15 gram sliders kick in faster and you run at a low rpm. so not good for take off, I am going to try 13 gram slider in it soon, and see what that will do,. what Wt,s are the GT 300 using,.
