The Exotek 22 5.0 Aluminum Laydown Idler Gear is a hard anodized 7075 alloy 38T idler gear option for the TLR 22 4.0-5.0 laydown gear box. This is a great option for high powered racing applications.
NOTE: This is much stronger than the stock plastic idler gear but not indestructible. It is important to use black or white grease on the gears and reapply frequently to prolong its life along with proper slipper adjustments.
