Re-gear fastest and most economical. If your lifted and 33s or bigger its the best 4:10 to 4:88s.

I added an inertia ring to the flywheel of my 2.5 and it is night and day as how well it climbs now. So much more down low that you can almost idle over obstacles. I have also done the standard mods that most people do that have the 4 cylinder, ie. 4.0 throttle body, bored the intake manifold to match the bore, 4 port fuel injectors, and cold air intake but I feel the inertia ring had the most impact on off road performance.
