| Finish Process | Vacuum PVD / Thermal Oxidation | Color is chemically bonded to the metal; won’t chip or flake. |
03. THE ENGINEERING JOURNEY (Aerospace Materials)
“Strength is nothing without reliability.”
Beyond Standard Fasteners: Most aftermarket bolts are decorative. Our Pro-Series Titanium is structural:
CNC Thread Rolling: Unlike cheap cut-thread bolts, our threads are rolled under high pressure, which aligns the grain structure of the titanium. This prevents the bolt from snapping under the high-vibration environment of a Big Twin engine.
Weight Optimization: By replacing the heavy steel bolts on your primary and cam covers, you reduce the “dead weight” of the engine, contributing to a more responsive feel for performance Baggers.
Dimensional Accuracy: Each bolt is measured to a < 0.02mm tolerance to ensure it bottoms out perfectly in the aluminum case without stressing the threads.
04. THERMAL & CLIMATE DYNAMICS (Built for the Elements)
Optimized for the extreme heat and humidity of the Middle East and SE Asia.
Zero-Oxidation: Steel bolts on Harleys are notorious for rusting in the “V” of the engine where water collects. Titanium is chemically inert to salt and moisture, ensuring your engine looks showroom-new for years.
Thermal Expansion Synergy: Titanium’s thermal expansion rate is closer to the aluminum of your engine case than steel. This reduces “bolt-creep” and maintains a more consistent clamping force during repeated heat cycles.
UV Resistance: Our PVD Gold and Burnt Blue finishes are UV-stable, meaning they won’t “bleach” or turn purple after sustained exposure to intense desert sun.
05. INSTALLATION & MECHANIC’S PROTOCOL
Proper lubrication is critical to prevent galling.
Anti-Seize Requirement: Mandatory. Always apply a high-quality copper-based or nickel-based anti-seize to the threads before installation into aluminum cases.
Torque Specs: Follow OEM Harley-Davidson service manual torque values (usually 10-12 Nm / 84-108 in-lb for case bolts).
Sequence: Always tighten in a “star” or cross-pattern to ensure the cover gasket seals evenly.
Cleaning: Use only mild soap and water to clean titanium. Avoid harsh acid-based wheel cleaners which can damage the anodized finish.
06. WHOLESALE & B2B INQUIRY
The perfect “point-of-sale” upgrade for performance workshops.
