Remember, the only real lift that gives you clearance is big tires.
I’d take polite issue with that. Aside from portal axles (which are probably a bit specialist) clearance isn’t just about the lowest point on your vehicle. There’s the far more important approach, departure and most importantly break over angles, all of which are improved by raising the body further away from the axles. Also by raising the body, you give more room in the wheel arches for greater articulation, should your setup allow for it. Lastly, you move your expensive and delicate panel work away from the rocks, which is never a bad thing off road. Obviously there are always swings and roundabouts; you lose out on cross slope performance (something to be avoided in any case) and you put your panel work closer to overhanging branches and the like.
Finally, the Navara is an IFS truck, so the front diff at least would actually be two inches further out of the way with a 2″ suspension lift.
Wholeheartedly agree about the HD springs though! 😆
