2,8541-Crawling for Mitsu Pajero, L200 and Montero!

These gears have been designed to directly replace the Mitsubishi low range transfer case gears as fitted to all models from the 4-cylinder NA 1983 on including the 3ltr V6 models.
No gears are as yet available for the 3.5ltr V6 models.

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. This is overcome with those gears!

TwinStick Transfercase

Twin Shift-Lever for Toyota Transfercase

This double lever replaces the original selector (2H-4H-N-4L).
You now do have the possibility to change independently between 2WD or all-wheel-drive and normal or low-range.
One sticks switches 2WD/4WD, the other one High/Low Range - absolutely independent!

More you get a 'real' freewheeling mode which is de-coupling both axles from each other - this might be of advantage e.g. while being towed.

The TwinStick is the ideal accessory for vehicles equipped with lokers in the front - no more stopping to open the hubs if you are in need for Low-Speed / 2WD.

The TwinStick fits the following trannies:
- G52 - W56 - R15x Series - W58/59

We have a simple yet efficient modification for the 4F-tranny (e.g. at the BJ42) which will take about an hour to enable a true 2L-gear!

The lenght of the sticks can be enlarged while ordering with no extra charge.

Cruiser Crawler Addon Transmission

This is the most easiest additionally reduction gearbox for Toyota LandCruiser (and others) - bolts to the back of the transfer, no altered propshafts anymore!

The crawler transmission effectively converts your transfer case into a 3-speed low range transmission. Normal low range is still available (2.02:1) or you can select the crawler transmission (3.05:1) or you can select both at once giving a total reduction of 6.16:1, effectively giving you a super low low range. This means the vehicle can be used in normal low range for normal off road track conditions and when the going gets tough or you feel like participating in some rock crawling you can simply select the crawler transmission and low range.

The unit may be operated in 2WD or 4WD.

The Gearmaster rock crawling transmission locates behind the transfer case in line with gearbox main output shaft. The new transfer case interface components transmit the power from the gearbox main output shaft into the Cruiser Crawler. The Cruiser Crawler transmission houses an input gear, idler gear, and an output gear. the drive from the gearbox main output shaft is directed either through the idler gear for a reduction drive or through the output gear for direct drive. The transmission requires compressed air to shift from direct drive to under drive.

No drive shaft alterations are required - tunnel and tank may need minor adjustments.

Fits:
40 series 1976 on with 31T input gear
55 series 1976 on with 31T input gear
60 series with 32T input gear
70 series with 32T input gear
80 series all models
100 series (live front axle only)
