Welcome to the wire! I've got a similar rig so hopefully i can help you out with some shock feedback.

On my 2 door Montero with 81k miles i recently switched from KYB to Bilstein 5100's just in the rear and that was a HUGE upgrade. I've been running KYB's for years and been perfectly happy with them but i thought i'd try something different in the rear of my SWB to help those leaf springs ride better. My truck went from feeling like a truck on leaf springs to feeling like a truck with the smoothness of coils. It's so nice i'm going to figure out the part number for fronts and swap those out as well.
