5th Gen 4.56 vs 4.88

For starters I used the search function and couldn’t find a clear answer.

I’m in the process of mapping out my build (don’t have my truck yet). My plan is a moderate build. Proposed vehicle will be a 2021 T4R TRD OR with about a 2.5” lift on 285s KO2S. I’ll probably do a hybrid front bumper and an off road type rear bumper plus a low profile roof rack. No rear tire carrier. So I will have some extra weight.

With that lift and tire size (which is fairly common it seems) what gear ratio would make the 4.0 the happiest? 4.56 vs 4.88 on a 5th gen T4R with a little extra weight? Use will be moderate trails, trips to Home Depot and possibly long trips on the freeway 300-400 miles. Will not be a daily driver.

 

I think the 4.56 would put you in the sweet spot.

 

Thank you sir!

 

I have a 2020 trd pro with 4.88's I pull a small camper with it and love the regear if to drive the interstate a lot at 80+ it will be geared a little low but any other place its night and day difference for the better. 80mph puts me right at 3000 rpm

 

Are you stock?

 

Yes but have plans to go to 285's
