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.

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.

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!
