Will the Britax Marathon ClickTight fit in a 2015–2024 Ford F-150 SuperCab?

Yes — the Britax Marathon ClickTight fits a 2015–2024 Ford F-150 SuperCab, with a caveat.
The Marathon ClickTight is about 18.5" wide; the F-150 SuperCab's usable rear bench is about 50". It fits one rear position comfortably. Three across is tight (55.5" needed vs 50"). Note: rear legroom here is limited, so a rear-facing install may crowd the front passenger.

Always confirm the fit and install yourself before every trip. The Marathon ClickTight's width (Britax published spec (~18.5 in)) and the F-150 SuperCab's rear-bench width (Ford dimensions + owner measurements (approx); extended cab — much tighter than crew cab rear) are both approximate — confirm with a test-fit before buying.

Common questions

Will the Britax Marathon ClickTight fit in a 2015–2024 Ford F-150 SuperCab?

Yes — the Britax Marathon ClickTight (18.5" wide) fits a single rear seating position in a 2015–2024 Ford F-150 SuperCab. Because this vehicle has limited rear legroom, a rear-facing install may require sliding the front seat forward. Three across is tight — its rear bench is about 50" and three of these would need 55.5".

Can you fit three Marathon ClickTights across a F-150 SuperCab?

Probably not — three Marathon ClickTights need about 55.5" but the F-150 SuperCab's usable bench is only about 50". Consider a narrower seat — see our narrowest-seats guide.
