LC 80 100 Extra Low

These gears have been designed to directly replace the Toyota Land Cruiser constant 4WD HF2A transfer case low range gears as fitted to FJ, FZJ, HZJ, and HDJ models built since 1990.

Vehicles fitted with automatic transmissions, STD or other wise can take advantage of the extra low, low range as an improvement in engine braking is realised giving greater off road performance and increased safety.

Vehicles fitted with larger tyres can regain lower than original gearing when fitted with these gears.

For example; 35" tyres will increase the ground speed of your vehicle by approximately 15%, with Gearmaster gears fitted you will still have a 10% lower overall ratio than a standard vehicle.
