Upgrade your Subaru’s reliability with the GrimmSpeed Timing Belt Guide — a precision-engineered solution designed to eliminate timing belt skip and improve long-term engine security. Unlike the thin factory steel guide, this unit is CNC-machined from robust 6061-T6 billet aluminum and finished with a Type II black hard anodize for exceptional durability. The increased adjustment range allows you to fine-tune belt clearance for optimized retention, while the included Grade 12.9 hardware ensures a rock-solid installation. Whether you’re running a stock setup or a high-performance build, this timing belt guide provides the stability your engine demands.
