Description

Fed up of looking at fuzzy white or crusty green factory bolts? This custom UK-made stainless steel engine bolt kit provides the crisp finishing touch your modern liquid-cooled V-Twin deserves. These are not just for show; they offer massive practical advantages over the standard mild steel originals, which are highly prone to freezing fast inside the aluminum block due to local winter dampness. With high-tensile stainless steel, you get easier maintenance access, zero paint stain worries, and a cleaner-looking engine case built for the long haul.

💎 Precision UK Engineering

100% Rust-Free Solid BuildWill not flake, scale, or turn dull even when blasted with constant wet front tyre mud spray. Superior Tensile ResistanceStronger and less brittle than original stock casing hardware to prevent snapping under torque load.

🔧 Install Tips

  • Torque Spec is Highly Important: Never brute-force or overtighten these fast bolts! The required layout torque for screws sliding directly into soft alloy side engine casings is very low—cap your settings to around **6 ft-lbs / 8Nm MAX**. Always use a light mechanical torque wrench.
  • Swap Method: Keep the side gaskets sealed by pulling out one old factory screw at a time. Clean the open engine threads gently with a cotton bud to lift old oil mist, then drop in the fresh matching bolt.
  • Use Anti-Seize Paste: Squeezing a very tiny dot of copper or nickel anti-seize compound down the thread lines is highly recommended if you commute on local roads during salty winter freeze cycles.
