The Bilstein B6 Rear Shock is a heavy-duty suspension upgrade for Toyota FJ Cruiser 4WD models running standard height up to a 2″ lift. Designed to improve rear-end stability, ride control, and durability, this shock performs reliably on-road and off-road. Built with Bilstein’s high-pressure monotube technology, it delivers consistent damping, better load control, and long service life—making it an excellent upgrade over factory rear shocks for lifted or stock FJ Cruisers.
