Take this from someone with a bit of experience with all types of lockers and a VX owner that has had a front ARB in for years. You do not want to install a non-selectable locker in the front. In fact if you want to keep the street manners of your VX don’t put one in the rear either. Your vehicle already has a very good limited slip in the rear differential that you can lock up pretty well with a little hand brake.
I do my own work and have over the years installed a number of ARB’s as well as Lockrights in vehicles that I own or for friends. In dry weather non-selectable lockers are just annoying with the ratcheting they do in a turn. In slick conditions you have to learn how to control the vehicle all over again.
I would recommend to all of you that before you install any locker, go on a trail ride with some folks that have both types of lockers (If you are interested in going off road a lot join a club) and either ride or ask if you can drive their vehicle. Ask them about the handling on road especially in snow.
I know cost is a big issue for some. Keep in mind, because of the labor, installing the front locker in the VX is going to be expensive no matter which locker you put in. You have to figure if it is really worth installing lockers for the very few times needed. Take it from me that a winch is a better investment and the first thing you should install if you are going to be doing a lot of challenging wheeling. And yes you can hide one behind the front cladding as a number of us have done.
