Exotek Racing - XB2 Aluminum Alloy Idler Gear, 25 Tooth HPI109291 Hot Racing's machined aluminum transmissionHard anodized 7075 alloy 25T idler gear for the complete Xray XB2 series of gear boxes. Must have for high powered racing applications. This is much stronger than the stock plastic idler gear but not indestructible so it is important to use black or white grease on the gears and reapply frequently to prolong its life along with proper slipper adjustments. Replaces the stock idler gear only (cannot mix and match sizes).
