The FTI Performance 9.5-inch Street Racer billet triple-disc lock-up torque converter for 4L80E/4L85E LT applications arrives with a 4000 rpm hard-hit stall for assertive launches. A CNC-machined billet front cover and billet lock-up piston work with tailored stator geometry and multi-angle pumps. Robust fabrication—furnace-brazed and heli-welded fins and severe-duty sprague—supports repeated heavy use without premature failure.
