Harley Transmission Covers

Buying Guide and FAQs

Buying Guide: Factors to Consider When Choosing Harley Bike Transmission Covers

• Compatibility: Ensure covers fit your Harley's model (e.g., Big Twin, Evo, Twin Cam, custom Softail/Dyna) and specifics like mounting holes (e.g., 8-hole for derby, 2-hole for inspection). Use the vehicle selector for year-specific matches to avoid fit issues.
• Type of Use: For aesthetic upgrades or custom looks, opt for derby/inspection covers; primary covers (inner/outer) suit protection and style in street riding; clutch actuators ideal for hydraulic systems in touring conditions.
• Components and Upgrades: Select derby covers with see-through windows or hidden fasteners, primary covers for narrow profiles, or actuators with banjo bolts. Focus on included hardware (e.g., bleeder screws) for complete installation.
• Brand and Quality: Choose PAUGHCO for chrome/black primary covers, Thrashin Supply Co for CNC-machined derby covers, Drag Specialties for narrow profile primaries, PRO-ONE PERF.MFG. for ball-milled/millennium derby covers, or TRASK for see-through assault covers. Prioritize cast/billet aluminum for durability and corrosion resistance.
• Installation and Cost: Most are bolt-on using OEM bolts; prices range from $28.95 for inspection covers to $317.95 for outer primaries—factor in finishes (chrome, black, gloss) and free shipping over $99 for value.
