💎 FRONT SPROCKET NUT & LOCK KIT | DRIVETRAIN SECURITY
Secure your front sprocket correctly and safely. The quality of this critical retaining hardware prevents catastrophic damage to your gearbox shaft and stops the sprocket from loosening under V-Twin torque. This is a non-negotiable safety upgrade.
- ✅ Safety: New locking tab guarantees security—do not reuse old parts!
- 🛠️ Material: Hardened steel construction resists thread stripping.
- ⚙️ Install: Must be torqued to manual spec with threadlock.
- 📦 What’s Included: 1x Nut (PN: 09159H20001) & 1x Lock Washer (PN: 09167H25004).
Description
Over time, the intense vibrations and torque from your 650cc V-Twin engine fatigue the locking tab washer and the threads of the retaining nut. The cheap components found on auction sites simply do not meet the tensile strength required for this high-stress application. This genuine-spec hardware is essential maintenance for life on the road , and ensures peace of mind that your sprocket will not come loose while riding.

🔧 Install Tips
- Torque Spec is Key: You *must* use a torque wrench and consult your service manual for the exact figure to avoid stripping threads or coming loose.
- Lock It Down: Use a drop of medium-strength thread-locking compound (Loctite Blue) for added security before bending the new washer tab into place.
