TECHTIPIdler Pulleys
Litens® routing idler pulleys and tensioner pulleys are produced to Original Equipment form, fit, function, and material specifications to ensure optimum performance and durability. Pulley materials may vary (plastic vs. steel) depending upon exposure to heat, location on the engine, and system tuning.
For best results, always replace idlers and tensioner pulleys with those made with the original equipment material selection.
