Trying to level out my suspension 2003 extra cab 2.7

I just Installed the rancho quick lift front coilovers and am about to get the rear shocks ordered ... I went from I'm guessing stock coils with a revtech leveling block that out of the truck measured 20.5 inches total length to the rancho that's 21inches the truck had 33s on it when I bought it but now I'm running 31s an that's what I'm staying with also have a arb bumper.... Standing back and looking at it I notice she does look to level front end to back the fronts lower..more noticeable than before I put the new coilovers on... I took a few pics of the rear leafs and was hoping to get some advice on leveling it out while using the rancho coils I'm not wanting to run bigger tires or rock crawl just have a reliable truck to go down muddy roads to hunt an fish on and drive down the beach thanks
