From what others have said in other forums, they've always stated that a front locker in an iFS hilux is better because when climbing uphill, as soon as you get one wheel off the ground, it'll wheel spin and as it lands, KABOOM, goodnight front diff. This was my main thinking in going the front locker first, protecting the front diff.
Does the rear Detroit Locker strengthen the crown wheel and pinion gear at all?
Any strengthening that you can get is an overall plus of the installation.
can we maybe organise a group buy to get some sort of discount?
