Litens 31316804 Alternator Decoupler Pulley

The Litens 31316804 Alternator Decoupler Pulley is an advanced replacement component designed to reduce vibration and improve the performance of your vehicle's alternator drive system. This precision-engineered pulley features Litens' patented decoupler technology that isolates the alternator from engine vibrations and belt fluctuations, resulting in quieter operation and extended component life.

Key Features:

• One-way clutch design allows the alternator to rotate freely during engine deceleration
• Reduces belt noise and vibration transmitted through the accessory drive system
• Dampening mechanism protects alternator bearings from premature wear
• Direct OE replacement for specific vehicle applications
• Engineered and manufactured to Litens' exacting quality standards
• Includes integrated pulley and decoupler mechanism in one assembly

Litens is the original inventor and leading supplier of alternator decoupler pulley technology to major automotive manufacturers worldwide. This decoupler pulley helps maintain consistent belt tension, reduces accessory drive system wear, and contributes to improved fuel efficiency by minimizing parasitic drag on the engine. The one-way clutch mechanism allows the pulley to overrun during sudden engine speed changes, protecting both the alternator and the serpentine belt system from damaging shock loads.
