Piston Pin Wire Lock Ring for KTM 85 SX & Husqvarna TC 85 2003-2026 - 47030074000

This OEM wire lock ring is a critical component for securing the piston pin within the piston assembly. It ensures the pin remains properly seated during high-RPM operation, preventing catastrophic engine damage. As a genuine factory part, it offers the precise tension and fitment required for reliable racing performance.

Compatible with a wide range of models including KTM 85 SX (2003-2026), KTM 105 SX/XC (2004-2011), Husqvarna TC 85 (2014-2026), and GasGas MC 85 (2021-2026). This part fits both small wheel (17/14) and big wheel (19/16) configurations, as well as SXS and XC variants across the KTM group brands.

Manufactured from high-quality spring steel, this circlip is designed to maintain its shape and tension under extreme heat and vibration. Replacing these rings during every piston or top-end service is highly recommended to ensure the integrity of your engine.

When installing, ensure the gap of the lock ring is positioned correctly to minimize the effects of inertial forces. Always use new clips when reassembling the piston to avoid fatigue-related failures that can occur with reused hardware.
