Meet our Partners: Litens (2) Clutch Pulleys vs Decoupler Pulleys

In case you're wondering what the differences are between clutch pulleys and decoupler pulleys, the primary difference is that decoupler pulleys are capable of completely disengaging from the belt drive system during engine deceleration , whereas clutch pulleys merely allow for slippage of the belt. This feature contributes to increased engine stabilization on decoupler vs clutch systems.  This also allows for a reduction in required belt tension at the tensioner itself. Primarily due to differences in belt tensioner strength between standard, clutch, and decoupler pulley systems, substituting between the 3 pulley types is not recommended. Although it may seem tempting to save a buck or two by buying a more cost effective pulley option, you will reap more long term benefits and be happier with vehicle performance by installing the part your car was designed for.
