TCI Drag Race Torque Converter, Lock-Up, 10" (1998-2006 GM LS1 & LS2 4L60E)

TCI® 9", 10" and 11" Drag Race Torque Converters can be run in applications with up to 750 horsepower and are most commonly used for a bracket race or street/strip application that leans more toward the "strip." Stall speeds vary depending on application but the average is 3800-4500 RPM for 9" and 10" converters and 3000 RPM for 11".

• Furnace-brazed and reinforced fins increase durability
• Needle bearings reduce drag & increase thrust capacity
• Three sets of Torrington bearings replace normal thrust washers used in OEM and some aftermarket converters to triple thrust capacity capabilities
• Hardened steel pump hubs increase strength, durability & longevity while decreasing wear
• Increased strength & holding capacity of high load sprags ensure stator stays locked when converter stalls & guarantees converter will stall correctly run after run
• Ballooning plates (9" & 10" only) double strength of converter when using transbrake and/or power adders
• 360° Steel mounting ring (9" & 10" only) strengthens mounting area of converter to flexplate
