Locking Tab Kit for Flywheel and Fastener Retention on 3 and 4 Cylinder Engines SKU: QT61865

When critical engine fasteners back out under vibration, the results can be catastrophic—loose flywheel bolts, damaged rotating assemblies, and expensive downtime. This locking tab kit provides mechanical retention that prevents fasteners from loosening, keeping your engine components properly secured where they belong.

Why Mechanical Locking Works

• Positive mechanical lock prevents bolt and nut loosening under constant vibration
• Designed specifically for flywheel and rotating assembly applications
• Clean-bending tabs create reliable contact against bolt flats
• Simple installation requires only basic hand tools

Perfect for engine rebuilds, clutch service, or any time you're reinstalling critical rotating hardware. The tabs are engineered to bend cleanly and hold firmly against fastener heads, giving you confidence that your work will stay tight. Compatible with common 3- and 4-cylinder engine configurations where flywheel security is essential.
