JIMS Tools Automatic Transmission Covers: Precision for Your V-Twin

When it comes to working on a Harley-Davidson's drivetrain, few details matter more than the quality of the covers that protect and house your transmission components. JIMS Tools has built a decades-long reputation for engineering products that meet the exacting demands of V-Twin mechanics — and their lineup of automatic transmission covers is no exception.

Built by a Brand That Knows Harley Transmissions Inside and Out

Established in 1967 by Jim Thiessen, JIMS has been manufacturing precision performance products for use on Harley-Davidson motorcycles for over 45 years. That long history isn't just a talking point — it reflects an intimate familiarity with how Harley transmissions are designed, how they wear, and what the mechanics servicing them actually need. JIMS manufactures only the highest quality 5 & 6 speed transmissions for many applications, which means their transmission covers are developed with a thorough understanding of the assemblies they're meant to protect.

Their mission has always been to set the standard for American-made precision products and tools for use on V-Twin engines. This mission is evident in every transmission cover they produce — parts that need to fit correctly the first time, seal reliably, and stand up to the heat cycles and mechanical stress of real-world riding and wrenching.

American Machining at the Highest Standard

From the beginning, precision and quality have always been the foundation of JIMS products, and the company is ISO 9001:2015 certified, meaning every component — including their transmission covers — is produced under verified quality management processes. Starting with just a few manual mills and lathes, JIMS now occupies several buildings totaling 50,000 square feet filled with CNC machines. That manufacturing scale allows for consistent, tight tolerances across their entire product range.

Many exterior parts such as engine and transmission side covers are handcrafted and available in stylish black anodized, polished, and chromium finishes, giving riders and builders the ability to match the aesthetics of a custom build while still benefiting from JIMS' engineering precision.

Tools and Covers Designed by Mechanics, for Mechanics

For many years, JIMS has offered tool solutions to make your work easier, faster, and safer — and their R&D department prides itself on creative thinking when it comes to design, backing that up with products that are warranted for life. That lifetime warranty philosophy extends to their transmission-related components, giving professional shop techs and home garage builders alike the confidence to invest in JIMS parts for the long haul.

Every product from JIMS is designed to save you time looking after your bike, and many of the same tools and components are used by mechanics at Harley-Davidson dealers because they're smart, well made, and designed to last. Choosing JIMS for your automatic transmission cover means choosing the same standard of quality that professionals rely on daily.
