Product Description

Penrite Shift Eze is a Transmission and Gear Oil Additive formulated with PTFE (Teflon) and Molybdenum to improve shift quality of manual transmissions and quieten noisy drivetrain gear systems such as transfer cases and differentials. It improves cold changing performance and provides increased load protection for competition and extreme loading situations.

Shift Eze is designed for use in all types of manual transmissions, transaxles and transfer cases. It can be mixed with Mineral, Semi Synthetic and Full Synthetic gear oils including those that contain Limited Slip additives, and with engine oils used in manual gearboxes.

Shift Eze is ideal for everyday use in manual transmissions to improve the shift quality, including the cold changing performance of the gearbox. It can be used to treat harsh gear changing problems, excessive noise and gearbox whine and as an ongoing maintenance fluid at recommended service intervals to enhance transmission smoothness and gearbox life. It may also be used as a Limited Slip Differential Additive to prevent chatter and provide smooth operation of clutch-type differentials. It can be used with old or new gearbox fluid.

How To Use

  • For maintenance add 125ml per 2 litres of gear oil.
  • Pour contents directly into gearbox, transaxle or transfer case.
