DAYCO 8 RIB IDLER PULLEY CONVERSION KIT TO SUIT HOLDEN L67 SUPERCHARGED 3.8L V6

Dayco Nuline Idler pulley is designed to provide reliability and performance, helping your belt last longer and provide reliable service to your engine for coming years.

These Idler pulleys (grooved and smooth) aid the conversion of an L67 Supercharged V6 engine to allow the use of an 8 ribbed serpentine belt and eliminates the risk of any belt slip and boost loss.

These pulleys are made of high quality material and utilise the best ball bearings, which are OEM manufactured and feature C3 rated high speed races, high temperature lubricant and heavy duty silicone seals for maximum service life at high RPM's.

These pulleys suit Holden vehicles fitted with the L67 Supercharged V6 engine.
