Colony Primary Mount Kits

26 products — part of all Primary Mount Kits

The primary drive chain case on a vintage Harley-Davidson carries oil, absorbs vibration, and holds its own against decades of mechanical stress — so the hardware that mounts it deserves the same period-correct attention as every other restoration component. Colony's primary mount kits are engineered for pre-unit and early-unit Harley-Davidson powertrains, covering Big Twin machines from 1936 to 1970, K model flatheads from 1952 to 1956, and the XLCH Sportster from its introduction in 1957 through 1969. Each kit delivers the correct bolt pattern, thread specification and finish to satisfy both mechanical function and the presentation standards expected of a properly restored machine. Colony has spent decades supplying the Harley-Davidson restoration community with hardware that makes a rebuild look and feel right, not just hold together. At Iron City Motorcycles in Leeds, our parts specialists can confirm the correct Colony primary mount kit for your build year and model. Browse the full Colony Primary Mount Kits range below.
