DETROIT LOCKERS AND DETROIT TRUETRACS

<< < (3/9) > >>

Mace:
Thanks for the info Neil.

Does the LSD act as an open diff in normal circumstances where you suddenly lose grip in one wheel and it's then spins relentlessly with the LSD never actually engaging?

Will it always engage or is it a case of almost every time having to left foot brake to bring the torque into the other wheel.

I've always understood the principle but never experienced the theory.

Thrasher:
Left foot braking is used to bring a front tru-trac in earlier than you'd expect. When there is a mismatch between the rotations the LSD will do it's business - remember an LSD is not a true locker - it is limited :-) However - when the going gets boggy it will run all 4 wheels :-)

Range Rover Blues:
A true trac isn't an LSD though is it, not in the traditional sense.  It's an Auto Torque Biasing diff, which is different.  As I understand (please jump in if you know) the ATB runs like a conventional diff unless one wheel spins out, then it biases torque flow to the slower wheel, up to 3 or 5 times depending on the model of diff, but not all the torque, hence the left foot thing.  I would have liked one for my sister as I understand that they drive like a normal car, even on slippery roads unless you wheel spin badly.  Detroit lockers can make things worse on an icy road (it says so in the instructions :roll: ).

Still trying to get my head round how an ATB actually works.

Just bought a pair of true tracs...i will report back when they're fitted and i've tried them  :lol:

iomlr:
I've fitted ARBs front and raer and this is easy also. the added bounce of teh air is you can pump up your tyres! Also makes a love boy racer PIsssssssssssssssttttttt. haha yes ok thats the only reason i bought them  :lol:  :lol:  :roll:
On a more serious note work a treat lock them as and when you need them! wicked!
