Lightened Input Ring Gear - Requires COA-32430 Bearing

The Coan Racing COA‑32780 Lightened Input Ring Gear is a race-focused enhancement designed for TH350 transmissions. Crafted from solid OEM-grade material, this gear has been precision-machined to shed unnecessary mass, delivering reduced rotational inertia and quicker throttle response without compromising structural integrity. Coan specifies that it requires pairing with the COA‑32430 bearing for proper support and alignment. This lightened ring gear not only optimizes performance by minimizing rotating weight, but it also bolts in directly, no housing or assembly modifications needed. Ideal for both bracket-race and street-strip applications, the COA‑32780 perfectly complements other Coan upgrades, providing a key component in performance-oriented transmission builds that demand precision, speed, and durability.
