Buying Guide and FAQs

Buying Guide: Factors to Consider When Choosing Harley Bike Primary Drive Systems and Parts

• Compatibility: Ensure parts fit your Harley's model (e.g., Evo, Twin Cam, Big Twin, Softail 1986-2006, FL/FLH 1946-1984, FX 1972-1984, Sportster/Buell 1991-2003). Use the vehicle selector for year-specific matches, including belt widths (1-1/2" to 3") and pitches (8mm to 14mm) to avoid power transfer issues.
• Type of Use: For classic open-primary style or kick-start setups, choose complete belt drive kits; street performance benefits from lightweight pulleys and tensioners for smoother operation and reduced weight in daily riding.
• Components and Upgrades: Select belts (132-144 tooth, ribbed), pulleys (30-70 tooth, front/rear), kits (with clutches, guards), tensioners (manual billet), spacers (starter), or adjuster shoes. Focus on hard anodized aluminum for durability and high-strength designs for reliable performance.
• Brand and Quality: Opt for Belt Drives Ltd (BDL) for premium kits and pulleys, Powerstands Racing for chain tensioners, Terry Components for starter spacers, or Baker Drivetrain for adjuster shoes. Prioritize USA-made billet aluminum and anodized finishes for corrosion resistance and longevity.
• Installation and Cost: Most parts are bolt-on with OEM hardware for easy DIY setup; kits may require additional components. Prices range from $49 for adjuster shoes to $651.95 for complete kits—factor in free shipping over $99 for value.
