As for traction, none of the 07+ Tundras come with an LSD (Posi), The factory “Electronic LSD” is just traction control, and is more “P.O.S.” than “POSI”. All tundras can benefit from the increased traction that an aftermarket LSD or Locker will provide. Another benefit is strength.
The Tundra uses a huge 10.5” diff that is much larger than any other ½ ton pickup produced. The problem is the factory Standard Open (non-posi) carrier is very weak by design, and has already failed in many stock pickups, this is all the more reason to add An Auburn Pro LSD ($545) or an ARB Air Locker ($1075) to the rear.
