Tacoma Master Install kit. (TECH NOTE) Please note that this kit does not come with factory shims, and the aftermarket shims really do not work well. You can buy a complete factory carrier bearing shim kit from us, and return what you don't use and recieve a refund minus the shims you used. Please don't be fooled by other companies telling you their shims are correct. They are not. We are the only company offering a complete set-up solution for this diff. Check out our Tech section for more info setting these differentials up.
