The FCS Split Keel PG Medium Quad Set is a replacement fin set designed specifically for FCS II PG Split Keel Quad systems — purpose-built to restore your quad's original performance with the same keel-inspired template the system was designed around.

• Split Keel Template — wide-base keel design generates exceptional drive and hold through longer turns while maintaining the straight-line speed that makes quads excel in small-to-medium surf
• Medium Size — designed for surfers 155–185 lbs; balances drive and pivot for mid-weight surfers who want a quad that pushes off the bottom and flows through open-face carves
• Performance Glass (PG) Construction — solid fibreglass construction delivers a stiff, responsive ride with predictable flex throughout the session
• FCS II Compatible — tool-free installation into any board with FCS II fin boxes; no key or screws required
• Set of 4 fins — complete quad replacement set, includes all four fins (two front, two rear)

Split keel fins move drive and projection from a single pivot point to the full rail — quads equipped with keel templates feel fast and locked-in on rail, with a skatey looseness through flat sections when you ease off the fins. The PG construction keeps the feel honest and predictable without the added cost of carbon or specialty laminates.

Fit Note: Confirm your board has FCS II boxes before ordering. FCS II fins install tool-free with a click-lock system — no screws or keys needed.

Care: Rinse with fresh water after sessions. Store in a fin bag to prevent edge nicks.
