FORWARD / DIRECT DRUM SEALING RING (RACE) USE W/ ALUMINUM & STEEL DRUMS

The Coan Racing COA‑22302 Forward/Direct Drum Sealing Ring (Race) is a precision-engineered sealing ring designed to enhance hydraulic sealing in TH400 transmissions. Specifically crafted for both aluminum and steel drums, this ring is fashioned from a high-performance material that offers exceptional resistance against fluid blow-by and leakage under extreme pressure and heat conditions commonly encountered in drag racing and bracket competition.

Intended for race-prepared builds, each sealing ring is sold individually, allowing technicians to replace only the worn components without necessitating full drum replacement . Their robust design ensures precise fitment and reliable sealing performance, making them an essential upgrade for any high-stress transmission scenario where maintaining consistent line pressure and minimizing fluid loss is critical to achieving optimal performance and component longevity.
