Fox Suspension Float X2 Performance Rear Shock. Fox Suspension’s Float X2 Performance Rear Shock benefits from many years of R&D development, which has refined its performance to hit the sweet spot. The Float X2 performance offers a more linear damping profile & benefits from revised seals & oil flow for super-smooth performance. It also offers a wide adjustment range so you can dial the performance of your downhill or enduro rig to perfection.
