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)

  1. 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.
  2. 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.
  3. 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.
  4. Do these covers include installation hardware? Yes, most come with stainless steel fasteners or screws for easy bolt-on installation.
  5. 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.
  6. 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.

Big Power, Nice Sound!

Picked up a Pro Circuit pipe and silencer for my YZ125 it’s a game changer. The power feels way better and the sound is awesome.

Perfect Fit

First time ordering here and dang y’all knocked it outta the park! The wheels fit my Ranger UTV perfect, and I’ll definitely be back for more 5 stars all day!

Helps keep cool, works great!

Bought the dual pass Allstar radiator for my build, and it’s been solid. Keeps the engine running cool even on the hottest days no complaints here!
