Buying Guide and FAQs
Buying Guide: Factors to Consider When Choosing Harley Bike Rear Master Cylinders and Parts
- Compatibility: Ensure parts fit your Harley's model (e.g., Sportster XL 2004-2017, FLT Touring 2008-2020, Big Twin) and specifics like bore size (3/4", 5/8", 9/16", 11/16"). Use the vehicle selector for year-specific matches to avoid installation or performance issues.
- Type of Use: For street cruising or touring, opt for standard master cylinders or rebuild kits for reliable braking; custom or performance builds benefit from billet assemblies for enhanced style and pressure delivery in demanding conditions.
- Components and Upgrades: Select complete assemblies, covers (dimpled/finned), gaskets (rubber), rebuild kits (seals/pistons), or pins. Focus on features like CNC-machined designs, anodized finishes, and included hardware for leak-free rebuilds.
- Brand and Quality: Choose Joker Machine for warrior-style covers, Drag Specialties for chrome assemblies, Covingtons for finned billet options, Accutronix for custom 5/8" bore, Eastern for black 3/4" assemblies, or Performance Machine for 11/16" rebuilds. Prioritize billet aluminum/steel with chrome/black finishes for durability and corrosion resistance.
- Installation and Cost: Most parts are bolt-on or direct replacements for easy DIY; rebuild kits simplify overhauls. Prices range from $10.15 for gaskets to $299.95 for assemblies—factor in USA-made quality and free shipping over $99 for value.
Frequently Asked Questions (FAQs)
- What Harley models do these rear master cylinders and parts support? Parts support models like Sportster XL (2004-2017), FLT Touring (2008-2020), Big Twin, and more—use the year/make/model filter for exact compatibility.
- How do billet master cylinders improve performance? They offer superior pressure delivery with custom styles and bore sizes (e.g., 5/8") for better braking feel and durability.
- What is typically included in a rebuild kit? Kits like Performance Machine include components for one master cylinder (11/16" bore), excluding cover gaskets—check details for specifics.
- Are covers and gaskets weather-resistant? Yes, with anodized/chromed billet aluminum and rubber gaskets for corrosion resistance and secure seals.
- What if a part doesn't fit my Harley? Verify bore size, finish, and model before buying. Our returns policy allows exchanges or refunds if it doesn't match.
