This TCI 4L60 Off-Road Torque Converter is the first in a new series featuring a low stall speed between 1800 to 2400 RPM to prevent "pushing through" the brakes when off-road, at low speed, or in stopped conditions. It is perfect for mild LS-swapped Jeeps or off-road rigs. The extra robust 10" converter benefits from a heat-treated steel pump hub and sprag races for increased strength and durability for trail abuse. The double-captured thrust bearings increase capacity while reducing drag, which is critical for off-road use. Features heat treated steel pump hub.
