From Exotek Racing:
Also for the TLR 22 3.0 standup gearbox.
Lightweight 3gr hard anodized alloy idler gear for the Loss 22S Drag. Reduces your rotating mass for more RPM’s at launch.
Direct replacement for the stock steel idler gear. Alloy is strong 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.
