Jims USA

Jims is a leading producer of performance parts, accessories, tools, transmissions, and high-performance engines for Harley-Davidson® motorcycles. Trust JIMS USA for unparalleled quality and performance in the motorcycle industry.

What Jims USA Makes

JIMS builds engine and transmission internals for Harley-Davidson, plus the specialty service tools that install them - cams and cam chest components, tappets and lifters, bearings, transmission gear sets and clutch parts, and a deep line of pullers, compressors, alignment fixtures and installation tools. What we list from JIMS moves as the catalog moves.

Fitment

Jims USA fitment is specified part by part, and coverage is not uniform across platforms or model years. Check that the fitment list on the product page names your model and year before ordering.

Engine Parts Go By Cam Chest, Not By Model

This is the one that catches people out. Two bikes of the same year wearing the same badge can take completely different cams, plates, tensioners and oil pumps, because what matters is which engine generation is in the frame. Read the fitment list on the product page against your own motor rather than going by the model name.
