Level up your V-Twin with FOX Street Performance suspension engineered for real-world riding. Our lineup covers IFP and IFP-QSR rear shocks, QS3-QSR piggyback and remote-reservoir kits, RC-1 piggybacks for maximum adjustability, and GRIP closed-cartridge fork upgrades. You’ll find model-specific fitment across Harley-Davidson Touring (’86–’25), Softail M8 (’18+), Dyna (’06–’17 front; ’91–’17 rear), and Sportster (’88–’22), plus Indian Scout applications. Every kit is tuned for predictable control, reduced brake dive, and long-mile comfort—fully serviceable and re-valvable so you can keep dialing in your setup as your riding evolves. Start with FOX rear shocks, add a GRIP fork cartridge, and transform how your bike tracks, turns, and brakes on any road.
