The FTI Street Racer billet lock-up torque converter for 700R4/early 4L60 applications is a 9.5-inch unit set to a 2800 rpm stall with a 27-spline output for street-oriented power delivery. Its CNC-machined billet front cover and billet lockup piston reduce premature clutch wear. Custom stator designs, multiple blade-angle pumps, furnace-brazed and heli-welded fins, and an anti-ballooning flanged impeller hub add durability.
