Exotek Racing - XB2 38 Tooth Aluminum Alloy Idler Gear, 38 Tooth COR00488-B J chassis and had aHard anodized 7075 alloy 38T idler gear for the complete Xray XB2 series of gear boxes. A 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, along with proper slipper adjustments to prolong its life. Replaces the stock idler gear only (cannot mix and match sizes).
