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.
Frequently Asked Questions (FAQs)
- What Harley models do these primary drive systems support? Systems fit models like Softail (1986-2006), FL/FLH (1946-1984), FX (1972-1984), Sportster/Buell (1991-2003), and more—use the year/make/model filter for exact compatibility.
- How do belt drive kits improve performance? They provide smoother power transfer, reduced maintenance, and classic open-primary looks with high-strength pulleys and belts for durability.
- What is typically included in a belt drive kit? Kits like BDL's include clutches, pulleys, guards, and belts (e.g., 132-144 tooth, 8mm-14mm pitch)—check details for kick-start or specific widths.
- Are tensioners necessary for primary chains? Yes, manual tensioners like Powerstands Racing prevent over-tightening, with billet aluminum construction for easy adjustments.
- What if a part doesn't fit my Harley? Verify model, year, and specifications (e.g., tooth count, width) before buying. Our returns policy allows exchanges or refunds if it doesn't match.
- Can I find related drivetrain parts? Yes—explore clutches, belts, sprockets, or full drivetrain kits in the Harley drivetrain category to complement your primary drive upgrade.
