Buying Guide and FAQs
Buying Guide: Factors to Consider When Choosing Harley Bike Engine Rocker Arms and Parts
- Compatibility: Ensure rocker arms 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 to avoid valvetrain or clearance issues.
- Type of Use: For high-lift cams or performance riding, select adjustable rocker arms with higher ratios (1.625:1); standard rebuilds benefit from OEM-style arms and bushings for reliable operation in daily conditions.
- Components and Upgrades: Choose rocker arms (forged/roller tip), shafts, supports, bushings, or kits; upgrade to high-ratio arms or bronze bushings for reduced friction and increased durability.
- Brand and Quality: Opt for Feuling for HP+ rocker arms with oil passages, S&S Cycle for forged arms and shafts, Andrews for high-ratio options, or Colony for bushing kits. Prioritize forged steel or billet aluminum for strength and longevity.
- Installation and Cost: Parts are designed for DIY valvetrain upgrades with basic tools; prices range from $20 for bushings to $400 for rocker arm kits—factor in USA-made quality and free shipping over $99 for value.
Frequently Asked Questions (FAQs)
- What Harley models and engines do these rocker arms and parts support? Parts support Twin Cam, Evo, Big Twin, M8, and models like Softail, Dyna, Touring—use the year/make/model filter for exact compatibility.
- How do high-ratio rocker arms improve performance? They increase valve lift (e.g., 1.625:1 ratio) for better airflow and power without changing cams, ideal for performance upgrades.
- What is typically included in a rocker arm kit? Kits include arms, shafts, supports, bushings, and hardware for complete valvetrain rebuilds.
- Are bronze bushings better than stock? Yes, they reduce friction and wear, with options for press-fit or roller bearings in high-load applications.
- What if a part doesn't fit my Harley? Verify engine type, ratio, and model before buying. Our returns policy allows exchanges or refunds if it doesn't match.
- Can I find related engine parts? Yes—explore valves, pushrods, or cams in the Harley engine category to complement your rocker arm upgrade for a full valvetrain refresh.
