There isn't a lift 'kit' for the xB out there. That said it can be done. For the rear you'll need to get longer shocks, custom spring, and a shim kit to fix the tow and camber after lifting it. For the front get in contact with 'Randode'. You'll find him on Facebook https://www.facebook.com/randodedotcom?fref=ts He's made some custom 2" spacers for the 2nd gen xB before.
