Buying Guide and FAQs
Buying Guide: Factors to Consider When Choosing Harley Bike Engine Covers
- Compatibility: Ensure covers fit your Harley's engine type (e.g., Twin Cam 1999-2017, M8, Evo, Shovel) and model (e.g., Road King, Softail, Sportster). Use the vehicle selector for year-specific matches (e.g., Twin Cam for Trask Assault, M8 for Slyfox timing) to avoid mounting issues.
- Type of Use: For street riding or custom aesthetics, opt for cam/point covers with aggressive designs; touring benefits from durable rocker/spark plug covers for protection and style in varied conditions.
- Components and Upgrades: Select cam covers (e.g., Assault/grooved), point covers (dish/finned), timing covers (matte carbon), rocker box covers (polished/chrome), or spark plug covers (finned). Focus on hardware inclusion and finishes for easy upgrades.
- Brand and Quality: Choose Trask for Assault series, Rough Crafts for grooved designs, Thrashin Supply Co. for dish point covers, Drag Specialties for rocker/spark plug options, Pro-One Perf. Mfg. for ball-milled point covers, Slyfox for matte carbon timing, Joker Machine for finned point covers, or Feuling for 5-hole point covers. Prioritize billet aluminum or forged billet for durability and corrosion resistance.
- Installation and Cost: Most are bolt-on with included hardware (e.g., stainless screws); prices range from $54.95 for point covers to $821.89 for rocker box sets—factor in made-in-USA quality and free shipping over $99 for value.
Frequently Asked Questions (FAQs)
- What Harley models do these engine covers support? Covers support models with Twin Cam (1999-2017), M8, Evo, Shovel, and Sportster engines—use the year/make/model filter for exact compatibility.
- How do cam covers improve engine aesthetics? Designs like Trask Assault with transparent windows or Rough Crafts grooved provide custom looks while allowing internal viewing.
- What finishes are available for covers? Options include chrome, black (anodized/powder coat), polished, raw/machined, or matte carbon fiber for style matching your build.
- Do these covers include installation hardware? Yes, most come with stainless steel fasteners or screws for easy bolt-on installation.
- What if a cover doesn't fit my Harley? Verify engine type, year, and design (e.g., 5-hole for point covers) before buying. Our returns policy allows exchanges or refunds if it doesn't match.
- Can I find related engine parts? Yes—explore gaskets, pistons, or cams in the Harley engine category to complement your cover upgrade for a complete refresh.
