Thread: True Trac or Detroit Locker

I'll test it with TC off just to see if the Truetracs go any further than open diffs, Then I'll test it with TC on, my prediction it will go to the end of the ramp (if it dosent roll first), will ad results to the image below & repost here, (just have to make a new top for the ramp as I sold that orange part with my trailer.)

BTW , yes I do have MD rear axles & Flanges thanks to Prev Owner and Ive since added MD front flanges but only to eliminate backlash but the front axles & CV's are original.

I fail to see what driving up a ramp on hard ground is going to prove.The minute that your front wheel come off the ground even with your TruTrac,it will fail to provide any further drive.You will get drive from the rear,until one of the rear wheels leaves the ground as well,and then you will fail to proceed.This is the point that a fully locked vehicle will continue to drive,to the point of clearing the obstacle or falling on its side

I'm following this thread with great interest, given I'm about to fit a pair of trutracs.

If I understand goingbush where he says

he will be undertaking a full set of experiments confirming that TC plus trutracs is almost the same as full lockers, but with less propensity to break anything ie sequence is

1 - I know how far it got before with TC & without truetracs.

2 - I'll test it with TC off just to see if the Truetracs go any further than open diffs,

3 - Then I'll test it with TC on

I reckon/hope he is right with 3 - QUOTE "my prediction it will go to the end of the ramp (if it doesnt roll first)

Good on you. Waiting with bated breath!!!!

I agree,that it should make it to the top of that ramp without any problem at all.Providing it keeps both rear wheels on the ground

But surely if the rear is locked, lifting a rear wheel becomes a non issue?

I understood that Goingbush had a Detroit locker in the rear of his Defender, if so he will go all the way to the top of the ramp or crash on his side.
If he has 2 Trutracs then his traction control will unsure the same result albeit not in a smooth controlled manner.
If he takes the fuse out of his traction control he will go the same height as a 110 without Trutracs

No Ive got Truetracs front & rear, I have a switch to deactivate the ABS /TC

Ive welded a new top on the ramp but now its raining so its not a fair comparison. I'll have to video the comparison because once I get up the ramp using TC It will roll back down if a wheel is off the ground, so I wont be able to get out & take the photo. It would not go far enough to lift a wheel at all with only TC and open diffs, we will soon see !!

Heres a pic of my old 90 hybrid driving up a Tree at Wagoo's place, Dual Maxidrives, you can see the front maxi actuator on the diff housing.


(not much articulation !!, I know on my 110 with standard suspension the crossup is much better. the 90 seems too light in the rear)


Once a wheel leaves the ground & I keep driving obviously I know the TT/TC combo is as good as 2 diff locks so I wont need to keep going to the top & risk rolling. It will start to feel tippy when / if the 2nd wheel leaves the ground.

Bill says the tree is gone now, I could find another tree but to be fair I want to compare with where the Defender went to on the ramp before.

I'll also go find a culvert to cross at 45 degrees then one front wheel and one opposite rear wheel will be off the ground without a risk of rolling, will video results with & without TC , hopefully later today or tomorrow.

Can't you use a two ramps to reduce the chances of falling onto your side?

Something like this, although in your case, the one that starts under the vehicle can't be a full height one.

i also have a winch, all i was highlighting is that with selectable lockers you can choose when to use them. I have been stuck with rear locker engaged which gave me the opportunity to get out and assess the situation to decide if the second locker is going to get me out of trouble or into more trouble.....
