There are many options for suspension with these rigs if you intend to go 2 inch conventional off the shelf set ups.
So long as you choose a reputable brand that provides a quality Shockyou got no dramas .
But if you think you're going to want to go more Eventually like I did with my triton then I suggest you go height adjustable shocks.
This way even if you can only afford to go suspension first and wish to do the upgrades over time adjustable height suspension will allow you to stay at 2 inch till you can afford to grab a diff drop kit and then wind them up further.
Triton are one of the most capable ifs dual cab rigs, pair them up with 3 to 4 inches of lift, diff drop kit, twin lockers and reduction gears (crawler gears) in the transfer and you will out wheel any other ifs ire in its class and keep up with twin locked cruisers and patrols
