Got this from an Australian forum. I figured some may have missed Misterbishi's post in another thread. Looks like we will very soon have ARB's available for all mitsu axles with the exception of the small front. This means we'll be able to lock a Gen 3 front and rear...Hmmmm..the wheels are turning now. Just wanted to spread the word..
"Hey got this email today
As a part of our on-going commitment to seek out and supply all of the possible applications for the renowned ARB Air Locker product, we have committed to developing the following Mitsubishi rear axle versions.
Production of the first of these, the RD156, will commence late this year and be followed in the first quarter of 2009 by the other 2 applications
RD154 Suits Mitsubishi 9.5"31 spline Live axles found in the rear of NL Pajero
V6 3500cc and all current modle Triton (L200).
RD155 Suits Mitsubishi 9.5"33 spline Independent (IRS) axles found in the rear of Pajero (montero) NM onwards.
RD156 Suits Mitsubishi 9.5"34 spline Live axles found in the rear of Hyundai Terracans.
These part numbers are now in our Distrib computer systems and can be back ordered through your local ARB branch as of 03/01/09 Pricing is not yet finalised.
So that's an RD156 for yours.
