Product Description
From 1999, Subaru added a small smooth idler pulley to help control timing belt flap on the left-hand bank, initially fitted with a single bearing. From 2002 this was uprated to a double-bearing design for improved durability. This kit allows the double-bearing idler to be fitted to earlier vehicles built with the single-bearing part.
