The TR cam gear set offers the final touch to your built EJ20/25. The 6061 T-6 Billet aluminum gears are hard anodized to prevent wear and provide low friction. The 2-piece design utilizing 5 hardened bolts provide maximum clamping force without sacrificing weight savings. Each cam gear has laser etched marking for easy adjustment of up to 10 degrees in each direction to allow quick tunability to gain the maximum horsepower from your camshaft selection.
