This kit replaces all the plastic wearable items in your primary & secondary clutch. These are wearable items we found best to replace every 1500-2500 miles depending on use, dust conditions, and maintenance habits. Uses our custom molded AA primary sliders. These custom molded AA primary sliders have a thicker bridge to add strength to the slider. This keeps them from breaking which is a well known issue with the thinner bridge OEM sliders. Anti-friction ridges are put on the sliding surface to decrease clutch/belt temperatures and make the clutch actuate quicker/smoother under load. Uses our custom molded AA helix buttons. Our custom molded AA helix buttons are a much stronger design due to our improved molding process. The factory part has voids which cause the buttons to easily break. When they break this can cause many issues including high engagement, poor performance, and premature clutch wear. Buttons should be broken in as they will mate with your helix. Being hard on them right out of the box is the most likely time to have a failure, even with our HD product.  For this, we suggest an easy cruise and varying MPH, but nothing with hard gas/brake or load/unload the clutch (like crawling). 2016 models can use these buttons with the OEM helix and they are much thicker (more wear time) over 2016 OEM buttons. Just make sure you break the buttons in for at least 5-10 miles if running the OEM 2016 helix. Highest quality material possible infused with teflon for added lubricity Replace your OEM stainless slider savers. These normally last quite a while, but if your sliders savers have grooves or are beat up due to a slider breaking; you'd want to replace them as well. Have a worn out/sticking primary clutch bearing causing the clutch to spin quickly at idle, even when properly aligned? Check out our replacement primary clutch center idler bearing.
