Premium Inner Outer Cam Bearing Kit Harley Twin Cam 88 1999-2006 b-148 6004c3

Upgrade your fragile factory cam bearings with this premium, heavy-duty inner and outer bearing replacement kit. Engineered specifically for 1999–2006 Harley-Davidson Twin Cam 88 engines (except 2006 Dyna), this kit replaces failure-prone stock components with high-performance industrial alternatives. Features two Koyo B-148 full-complement inner needle bearings to eliminate plastic cage failures, and two Nachi 6004 C2 tight-clearance outer ball bearings to reduce shaft runout and vibration in the cam support plate.
