    Hi guys,

    We've been debating this on another forum and was wanting to see what the thoughts from this one were. In Aus. our TJs come with a D30 front and D44 rear diff. Once you start getting above 35" tyres, the D30 at the front starts looking pretty weak.

    Looking at different options of upgrading the diffs. One option was to put D60's under, but to purchase and build those up with lockers and the right ratios etc is going to cost around AU$15k, which is pretty expensive.

    Other options are to beef up a D44 for the front with 35 spline Warn axle and modified 35 spline locker, along with beefing up the rear with the same gear.

    Does anyone have any thoughts/suggestions on either of these options, or any other options?
