Commander QT-II vs Toyota Fortuner with diff lockers
In the same off-road trip which I tested the Traction control Off and ON, my friend and I found a hill formed by sand and loose rocks which seemed to be easy.
My friend has a Toyota Fortune powered by a V6 engine 4.0L and rear diff locker, he also added an ARB air-locker in the front diff, so that he have full locking 4WD system.
After couple of attempts which disproved our initial thought about the easiness of hill, he managed to get up the hill using 4Low and both diffs locked. Then I tried also couple of times and managed to get up there using 4Low (Traction Control ON, fuse was in place), This video shows both successful attempts …
Although the real lockers are assumed better than the Traction Control, this simple test can tell that Traction Control can achieve really close performance to the real lockers.
What I concluded from the two tests I made is that QT-II with Traction Control can achieve close performance to real diff lockers, so that adding real lockers might be not cost effective. (Your opinions about this thought is really appreciated)
In other hand, the Traction Control puts alot of load on the break system and break pads which might affect the system negativity after time. but real lockers can stay functional for long
