Exotek Racing XB2 7075 alloy idler gears

Exotek Racing have introduced these hard anodised 7075 alloy idler gears for the complete Xray XB2 series of gear boxes. Available in 38T, 36T and 25T, they are 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 to prolong its life along with proper slipper adjustments.
