Regear with 37s

It’s a long story. I worked with a performance shop to install aftermarket suspension and springs on the rear end. Somehow, the e-locker sensor wiring harness ended up partially plugged into the differential, causing it to malfunction and partially lock. I never heard or felt anything different in the truck, but apparently it ground the gears and the differential fluid is like metallic toothpaste. The e-locker is broken and Toyota will only fully replace the diff, they don’t do repairs. I checked with another shop and they confirmed gears aren’t available for the truck and I’d have to buy one from Toyota either way. $4,500 installed. Life’s fun sometimes!

 

Thank you for sharing. Fun fun

 

Any news on gears coming out for these trucks?

 

I called ECGS recently, they confirmed the gears are unfortunately different from other gen trucks. Maybe the 1st ever locker in a Tundra caused the difference.
Heard it would be a couple hundred thousand to invest.

Maybe we could play the group buy card, get 30 to 50 owners to buy in? Then bring that to a mfr

My truck never uses 10th gear on 285/75-18 34.8"

I'd want 3.9 or 4.10s for up to 37s
3.90 is an 18% jump from 3.31
4.10 is a 24% jump from 3.31

A 24% jump from 32.6" tires takes you to 40.3"
