About this part

The Exotek XB2 Alloy Idler Gear is a hard anodized 7075 aluminum 38T idler gear option for the complete XRAY XB2 series gear boxes. This heavy duty gear is a must have for high powered racing applications. This gear 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.

NOTE: Replaces the stock 38 tooth idler gear only (cannot mix and match sizes).
