Old thread but I am going to bump it....
I have a set of G3 Portal-Tek axles under my 83 Nissan Patrol. I bought the axles in late 2007. Portal-Tek went belly up in early 2010 not long after introducing the Super 14.
Torq Axle in SLC, Utah has bought the rights, designs and all that jazz from Portal-Tek. It is looking like they will be putting the Super 14 back into production in early 2012. I don't know if they will be producing the G3s, however I think that is their plan. They will be supporting past purchasers of the Portal-Teks which makes me happy!
I have RCV CV axles in the front steering axle under my Patrol. This is a very nice axle with a 45 degree turning radius. I have had next to no issues with my axles and if you want the best ground clearance out there plus extremely strong axles, the G3s and Super 14s are going to be very hard to beat. Not to mention you can order them at any specs since they are not an old axle built for a military truck. That means off set, axle tube size, axle grade (4340 or 300m), width, gear set and more can be had since these are built to order.
A very nice product and I for one am stoked Torq will be moving forward with this.
cheers
