4L80E Competition Components

Use with engines producing up to 1300 foot pounds of torque in vehicles weighing up to 4000 pounds. Will handle more torque in lighter vehicles. Mainshaft is manufactured from 300M steel billet blanks. Undercuts behind the splines are reduced, resulting in increased spline length and diameter, increasing spline engagement at the forward clutch hub and rear internal gear interfaces.   Fully machined, shaped, and ground on precision CNC equipment. Fits 91-96 models

Use with engines producing up to 750 foot pounds of torque in vehicles weighing up to 4000 pounds. Input shaft is manufactured from proprietary steel billet material. Undercuts behind the splines are eliminated, resulting in increased spline length and diameter, increasing spline engagement at the overdrive planetary carrier interface.  Fully machined, shaped, and ground on precision CNC equipment.
