Flyer's '02 Tundra adventure build

[smokeysevin]

4.56 with 315's will be essentially stock, have been running 4.56 with 285's for almost 10 years at this point and I would say for 315's (34.5") 4.88 should be a minimum.

My 255/85/16 Coopers measure 33". Would you still recommend 4.88?

I'm 488 and 35s.
I wouldn't run 488 and 33 imo.

Thanks for all the input, guys. Hard choice, to be sure, but right now I'm leaning towards 4.56. I really liked the stock performance and I'm just a little afraid of going too low-range with 4.88's.

Where does the speedo get its info on this truck?

Difference is about 7% between 4.56 and 4.88. So a cruise, you’ll see about a 7% difference. So 2500 becomes 2675. So compare that to the torque curve of the engine.

I’d not hesitate to do 4.88’s, personally. Especially if there is going to be any towing. Even if it’s just around town.. or especially if it’s just around town... or if you ever plan to go to a larger tire (bfg’s 34*11.5 looks like a great DD size), then I’d also go 4.88. My wife doesn’t know this, but I’m sincerely thinking of putting 4.88’s in her gen5 4Runner. ?

For speedo, I used a Yellr box with the pigtail. Works awesome. Www.yellr.com

Unless you plan on going to 35s later I wouldn't hesitate to go 4.56s. I actually have a full 3rd member with 4.56's and a trd kazuma limited slip if you are interested. I have no need for it anymore. To get back to stock reading on 33s you need (iirc) 4.30 gears, with 4.56s you get a nice torque bump without a huge hit on mpg.

Pm me about your parts please. I already have a factory LSD, but I'm def interested in the gears so that's an easy swap. Then for the front end...

PM sent, as a side note the TRD limited slip was advertised at (iirc) 300% stiffer clutch packs.
