    Hello all..2019 F 150 XLT 4X4 CC. I just installed a Halo 3inch coilovers and 3inch block. I have 3.55 gears with a 10 speed. My question is, should I change the gears to 3.73 or 4.11. Every chart on gearing says I should yet with a 3.5 Eco not sure if it's worth it. Fuel Contras with Nitto Ridge Grapplers 285 70 18.
