Litens 920802A Overrunning Alternator Decoupler Pulley

The Litens 920802A is a high-quality replacement pulley engineered to OEM specifications. Litens is the original inventor of the overrunning alternator decoupler (OAD) and overrunning alternator pulley (OAP) technology, and their pulleys are trusted by major OEM manufacturers worldwide for precise fitment and long-lasting performance.

This pulley is designed to reduce noise, vibration, and harshness (NVH) in the accessory drive belt system by allowing the alternator to overrun during deceleration events, decoupling it from the belt to smooth out rotational irregularities. The result is a quieter, more efficient drive system and reduced belt wear.

Key Features:

• OEM-quality construction for direct, no-modification installation
• Engineered to reduce belt slap, chirp, and accessory drive vibration
• Helps extend belt and tensioner life by minimizing dynamic loading
• Built to withstand high-cycle fatigue and thermal stress
• Meets or exceeds original equipment performance standards
• Manufactured by Litens — the original innovator of OAD/OAP pulley technology

Replacing a worn or failed alternator pulley with a genuine Litens 920802A restores proper accessory drive operation and helps prevent premature wear on belts, bearings, and other drive components.
