This Dual Idler Assembly is designed to reduce the oscillation of the belt on the tension side allowing improved contact wrap with the drive pulley. This is a particular advantage on dragsters using a small 32 tooth top pulley. The system also incorporates quality high speed bearings in (2) crowned pulleys** for improved belt life well over 11,000 RPM
**Pulleys are 3.400" wide (86.4mm) and are designed to be used with an 84mm wide belt.
We also offer custom 8mm 32 tooth top & 8mm 75 tooth bottom pulleys made from 7075-T6 aluminum with stronger bodies that reduce flex and improve belt life. See "Blower Pulleys"
