Robert did an awesome job breaking down the pros and cons of 2.0 vs 2.5 coilovers. It sounds like you would be fine with a 2.0 setup, however, i wheel the shit out of my 2.5" bodied, extended travel Icons, the ride and flex i get offroad is incredible and the on-road feel is awesome as well. You dont see too many Icons or SAWs on here, both are top notch brands but i think the cost is a lot for most to stomach when Toytec sells much cheaper setups.
If you are thinking of upgrading to a UCA, i really like my LR arms, they have a sealed oversized balljoint that is replaceable and wont ever squeak like a spherical joint will on most aftermarket UCA. Light Racing arms are also the ONLY aftermarket UCA that is adjustable to dial in how you want your truck to drive and meet alignment specs. All others just have a set amount built into the arm. Any questions let me know, your truck is really coming along great!
