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.
Frequently Asked Questions (FAQs)
- What Harley models do these transmission covers support? Covers support Big Twin, Evo, Twin Cam, and custom Softail/Dyna models—use the year/make/model filter for exact compatibility with stock H-D or aftermarket primaries.
- How do derby covers improve style? Designs like ball-milled, smooth, or see-through windows (e.g., TRASK with acrylic) add custom aesthetics with 8-hole mounting for easy swaps.
- What is typically included with clutch actuators? Actuators like PRO-ONE include 10mm banjo bolt, washers, bleeder screw—require separate 11/16" bore master cylinder and hydraulic line.
- What materials are used in covers? Primarily cast aluminum or billet aluminum with chrome, black (gloss/anodized), or raw finishes for style and durability.
- What if a cover doesn't fit my Harley? Verify mounting style (e.g., 8-hole derby, 2-hole inspection) and model before buying. Our returns policy allows exchanges or refunds if it doesn't match.
- Can I find related drivetrain parts? Yes—explore clutches, belts, sprockets, or full kits in the Harley drivetrain category to complement your transmission cover upgrade.
