JIMS Parts & Tools

Since 1967, JIMS has been committed to providing a better experience for all Harley riders with their performance parts, accessories and tools. Beginning as an aerospace machinist who also dabbled in motorcycles, founder Jim Thiessen eventually transitioned to V-Twins full-time, responding to customer demands for high-quality, hard-to-find American made components. Now occupying 50,000 square feet of high-tech manufacturing space, this family-run company continues to develop new parts and processes that have earned the trust of enthusiasts worldwide. <br><br> JIMS transmission parts are used by the fastest Harley riders on the planet, including BUB Speed Trial record holders and AHDRA winners. From Harley mainshafts and kickstarter shafts to replacement gears, each part is CNC-machined to the tightest tolerances for everything from daily work commutes to drag racing. JIMS transmission rebuild kits are a great way to freshen or upgrade your current drivetrain, and you can also pick up lockdown axle kits for increased reliability and safety during high-stress riding. <br><br> If your engine is constantly threatening to overheat, adding a JIMS head cooler will allow you to comfortably keep pushing the limits. The JIMS Forceflow cylinder cooler aims a fan directly at your heads to reduce temperatures up to 100 degrees, and can be set to run automatically with a thermostat sensor. And if you’re always struggling to find the right shop tools for the job, you’ve come to the right place. JIMS motorcycle tools are available for adjusting clutches, installing exhaust gaskets, removing camshafts, aligning ignitions and much more to turn you into an expert mechanic. <br><br> Dennis Kirk has the best selection of JIMS Harley-Davidson parts and tools at the lowest prices so enthusiasts of all levels can afford to experience great performance and reliability.
