8991K Camshaft needle bearing. Inner

Upgrading your inner cam bearings is a smart move during any cam swap, and these JIMS full needle style bearings are the industry standard for reliability. Unlike the standard caged bearings that can fail under high loads, these provide a full complement of needles for maximum support. They are sold as a pair, which is exactly what you need for 2006 to 2017 Dyna models and 2007 to 2025 Softail, Touring, and Trike models. While Milwaukee-Eight engines only require one, Twin Cams need both. These are a direct upgrade for OEM 9215, 9298A, and 9298B, and are the same high-spec full needle bearings found in the Screamin' Eagle 24018-10 sets. They offer the peace of mind every mechanic wants when closing up a cam chest.
