Harley Crankcases and Parts

Buying Guide and FAQs

Buying Guide: Factors to Consider When Choosing Harley Bike Engine Crankcases and Parts

• Compatibility: Ensure crankcases and parts fit your Harley's engine type (e.g., Twin Cam, Evo, Big Twin, M8) and model (e.g., Softail, Dyna, Touring). Use the vehicle selector for year-specific matches (e.g., 1984-1999 Evo, 1999-2017 Twin Cam) to avoid assembly or fit issues.
• Type of Use: For standard rebuilds, opt for OEM-style crankcases; high-performance engines benefit from S&S V-Series for increased displacement (e.g., 100ci to 124ci) and power in demanding riding conditions.
• Components and Upgrades: Select crankcases with pre-installed bearings/seals or parts like snap rings, pinion bearings, and spacers. Upgrade to kits with high-strength materials for better oil flow and durability.
• Brand and Quality: Choose S&S Cycle for premium V-Series crankcases with forged internals or Drag Specialties for affordable bearings and spacers. Prioritize USA-made billet aluminum or steel for heat resistance and longevity.
• Installation and Cost: Crankcases require professional installation; parts like bearings are DIY-friendly. Prices range from $4.95 for snap rings to $3,295.95 for premium crankcases—factor in free shipping over $99 and expert support for value.
