Decklid panels fit the full 2015-2023 range, with one exception, GT500's carbon fiber panel is scoped to 2020-22. Trunk weatherstrip and lift supports split by body style (coupe vs. convertible), and lift supports further split by whether your Mustang has a rear spoiler. The V3 Coyote and V2 Boosted emblems are shared across nearly every Mustang generation, 1979-2025, so they're not S550-specific. Not sure which decklid panel or trunk weatherstrip fits your Mustang? Our S550 exterior specialists can help you confirm before you order. Be sure to check out our rear bumpers and rear wings and spoilers to further complement your Mustang's rear appearance!
