JET Powr-Flo Servos are designed for truck and SUV applications with 700-R4 transmissions. The Billet Powr-Servo features a much larger apply area to prevent band slippage under heavy throttle or heavy towing. The 4th Gear Billet Servo prevents band slippage in 4th gear, which aids in acceleration and towing. 2nd gear and 4th gear servos can be installed together for improved shifting in all gears.
