Alloy Idler Gear 39T for B6.3 Laydown (ETK2034)

Alloy 39-Tooth Idler Gear for B6.3 Laydown Gearboxes is a hard‑anodized 7075 aluminum replacement designed to replace the stock plastic idler in B6.3 laydown gearboxes, especially under high‑power racing conditions. The 39‑tooth gear is built to handle demanding setups, delivering improved strength and durability where fast, torque‑heavy driving is common.

Designed for B6.3 laydown gearboxes (and compatible B6.2 layouts), this 39‑tooth idler gear supports robust performance in racing applications. While significantly stronger than the stock plastic idler, it is not indestructible; to maximize life, apply black or white grease to the teeth and reapply frequently, and keep slipper adjustments properly set to maintain smooth gear mesh.
