The gears suit all model transfer cases enhancing the vehicles off road performance and safety. Vehicles fitted with larger tyres to enhance their off road performance are at the same time handicapped by this improvement as the increased tyre diameter reduces the engine braking on steep descents. The increased tyre diameter also increases the speed of the vehicle in all gears making steep ascents and rocky terrain difficult to traverse safely.

Vehicles fitted with automatic transmissions have very poor engine braking, this is due to the 1st gear ratio being in the order of 2.7 to 3.5:1 and to compound this problem the torque converter can not be locked  up in this gear. The 48% gear reduction gives an outstanding improvement to the engine braking and overall drivability of the vehicle. If you own an automatic 4WD vehicle and have taken it off road in a hilly area you would appreciate the improvement in safety and drivability that these gears offer. 

If you intend fitting or have fitted a GM engine and automatic transmission to your vehicle you should also consider fitting these transfer case gears to improve your engine braking and general off road performance and safety.

When winching your vehicle you often need to give some assistance to the winch by driving the vehicle  in 1st gear, however the STD overall ratio moves the vehicle much faster than the winch. This over speed of the vehicle can cause excessive loading on the winch and cable when the vehicle looses traction. The cable can also become crossed up causing premature wear and possible breakage. The lower speed achieved with the gears means that you can better match the vehicle speed to the winch.

All Mitsubishi transfer cases are fitted with backlash eliminators this is to help prevent low speed gear chatter which is more commonly experienced in vehicles fitted with automatic transmissions. All of our Mitsubishi gears are supplied with a new back lash eliminator which is designed to suit the new gear tooth profile.

The transfer case does require a small modification to fit the gears, the installation is relatively simple allowing the job to be undertaken by most mechanical work shops. (NOTE that a Mitsubishi workshop manual is required.)
