This customer wanted to build a big stable Troopy for touring. One of the weaknesses of the 70 series Landcruiser's is there relatively narrow track. So for this build we installed our custom widetrack kit which uses custom Dwiz diff housings front and rear to increase the track width by nearly 100mm on the front and close to 200mm on the rear, all on 315/70R17 tyres with offset rims giving it an excellent scrub radius. The hardware fitted to the axles is mostly factory 70 series with some 105 series components which makes servicing them simple.
To give the vehicle some stance and some clearance off road we added a 3 inch suspension kit. Our customer wanted to increase his GVM as well so we spec'd and tested everything at 4.2T. To keep the ride respectable at this height we threw in some heavy duty Parabolic springs which although capable of carrying the weight are still give a far better ride than conventional leaf springs. Not as good as a set of coils, but a big step in the that direction. To finish of the suspension we used some Blackhawk radius arms and a set of Dobinson remote reservoir shock absorbers.
The braking on these Landcruiser's is another weakness, especially when the GVM is lifted to 4.2T. To sort this we added an upgraded Terrain Tamer brake booster and our custom 200 series brake upgrade kit. This kit allows the fitment of 200 series Landcruiser brakes on to the 70 series. Like with the axles the serviceable parts are all Toyota and available anywhere in Australia. The difference as you would expect is significant and well worth the expense.
To certify a build like this we need to perform brake testing as well as the infamous lane change test. We have tested a lot of big Landcruiser and this was easily one of the best handling rigs we've tested.
