Planetary Reaction Carrier Bushing

PLANETARY REACTION CARRIER BUSHING

The Coan Racing COA‑22513 Planetary Reaction Carrier Bushing is a precision-engineered component designed to reinforce and maintain optimal alignment within high-performance TH400 transmission planetary assemblies. Crafted in the USA to exacting tolerances, this bushing fits snugly within the reaction carrier, offering essential radial support that reduces internal wear and helps preserve proper gear mesh under the ferocious torque spikes often seen in drag racing and performance driving. By replacing worn or undersized factory bushings, the COA‑22513 improves rotational consistency and hydraulic integrity, contributing to smoother internal operation and extending the lifespan of the planetary gear set.

Part of Coan’s extensive bushing lineup for TH400 transmissions, this planetary reaction carrier bushing delivers a direct-fit upgrade without requiring any case modifications. Its high-grade construction ensures durable resistance to heat and wear, helping to stabilize the carrier under heavy loads. Whether used in a rebuild or performance enhancement build, the COA‑22513 provides a race-ready level of internal support and precision alignment, keeping transmissions functioning reliably and efficiently in the most demanding environments.
