Not quite sure what you're asking. If you're asking whether some 4runners came with 4.88s, then yes, they did just as you said. Like adam said, you can't regear, but the factory 4.88s are supposed to be the strongest setup.

Here's a pirate thread on the subject: http://www.pirate4x4.com/forum/showthread.php?threadid=143618

If you have to ask about a SAS, you're not ready for it.
