Serpentine Belt and Pulley Kits come in a wide range of colours (Polished, Black, Blue, or Red) and provide almost no belt drag like V-belt systems. These high quality kits fits upright engines only and spin the fan quicker (no slipping!) and are easily adjustable.

These kits use a FULL SIZE pulley for maximum cooling!

These complete kits come with the crank and clternator/generator pulleys, idler bracket, high quality idler bearing and idler adjuster and all of the required hardware.

Serpentive belts do not slip nor flip, they are more efficient than V-belts. However, because they do not slip we do NOT recommend that you use a Serpentine belt if your engine's RPMs exceed 6000 as it "over-speeds" the fan, since it doesn't slip like a V-belt does. This exposes the fan to more RPM's and they may fail.

A Serpentine belt system is ideal for Cruisers (especially buses) that tend to run hot as you get maximum cooling airflow with a Serpentine Belt System.
