Suncoast 10" Maximum Performance Converter w/ Billet Cover - Torque Drive Lock-Up, '98-Up LS Engine (Except Corvette)

 

10" MAXIMUM PERFORMANCE CONVERTER W/BILLET COVER (TORQUE DRIVE LOCK-UP)

• 281MM bolt circle '98 - UP 4L60E LS engine (except Corvette)

 

Crafted specifically for 1998‑up 4L60E transmissions paired with LS engines (excluding Corvette applications), the COA‑110310 delivers elite performance in a robust 10″ format. Featuring a CNC-machined billet cover, this torque converter ensures rigid structural integrity and precise sealing under extreme load. Its standout feature is Coan’s Torque‑Drive lock‑up mechanism, engineered to maintain full lock-up under high torque, reducing slippage and boosting efficiency once the converter engages. Unlike stock converters that may balloon or weaken under pressure, the COA‑110310 leverages Coan’s Maximum Performance design philosophy, incorporating high-strength internal components and precision-balanced to deliver stable hydraulic flow, heat resilience, and repeatable performance. With its 281 mm bolt circle, it installs seamlessly into eligible 4L60E transmissions, offering enhanced throttle response, reduced fatigue during intense driving, and a confident, firm lock-up feel without compromising drivability. Fully built in the USA to Coan Racing’s rigorous standards, the COA‑110310 is the converter of choice for enthusiasts seeking uncompromised competition readiness and daily reliability.
