2015-2023 Mustang S550 DuckTail Trunk With Integrated Wing
Replace the factory steel decklid on your 2015-2023 S550 Mustang with a full carbon fiber trunk that integrates a sculpted ducktail wing into a single bonded panel. Engineered for every fastback trim — EcoBoost, GT, Mach 1, GT350, and GT500 — with high-gloss UV-protected carbon fiber that won’t yellow with age.
High-Gloss Carbon · Direct Bolt-On · All Fastback Trims
Lead time: 3-5 weeks (per Muscle Auto Zone)
This trunk is laid up and finished to order at MAZ. General lead time is 3-5 weeks from purchase to ship. Plan your install accordingly — FFP will confirm your exact ETA at order placement.
Sleek, aggressive, race-inspired.
The S550 Mustang’s factory rear end is iconic — but if you’re running an EcoBoost, GT, Mach 1, GT350, or GT500, you’ve probably eyed the GT500 KR’s flowing ducktail and wondered why every Mustang doesn’t ship with that profile. MAZ’s 2015-2023 Carbon Fiber DuckTail Trunk gets you there in one swap: an integrated ducktail wing rises smoothly out of a full carbon-fiber decklid, transforming the rear three-quarter the way Ford’s design team flirted with but stopped short of putting on the lineup. Aerodynamic at speed, statement-making at rest.
This isn’t a bolt-on spoiler glued to a steel trunk. The wing is part of the panel. The flowing transition from decklid to lip is laid up in continuous carbon fiber, sealed under a UV-resistant high-gloss clear coat that won’t yellow or fade. Drop it on, run the factory hardware through it, and your S550 stops looking like every other Mustang in the parking lot.
Fits Every 2015-2023 S550 Fastback Trim
MAZ engineered this trunk to share the same outer geometry as Ford’s factory S550 fastback decklid — so it bolts onto every fastback trim in the 2015-2023 generation, regardless of engine or package. Convertible models excluded.
Recommended Install Hardware
Per MAZ: M6 × 1.00 bolts, 12mm or 14mm length depending on your specific vehicle’s hinge configuration. FFP will confirm the right length when you order. The OEM trunk hinge bolts may also be reused on most builds.
What Makes MAZ’s Trunk Different
Integrated Wing & Decklid
The ducktail isn’t bolted on top — it’s laid up as one piece with the trunk. No gap, no glue line, no risk of separation at speed. Cleaner aero, cleaner aesthetics.
Aggressive DuckTail Profile
The wing rise is engineered to add a sculpted, race-inspired silhouette without going overboard. Performance-oriented but street-credible — reminiscent of the GT500 KR profile.
High-Gloss Carbon Fiber
Full carbon fiber lay-up — substantially lighter than the factory steel decklid. UV-protected high-gloss finish that won’t yellow over time. Matters at the rear axle for handling, matters for the visuals every time the trunk’s open.
UV-Protected Clear Coat
Clear-coat UV protection is what separates carbon parts that look great in year three from carbon parts that yellow into amber. MAZ specs the UV layer up front so the gloss stays gloss.
Universal Fastback Fit
One trunk fits the whole 2015-2023 S550 fastback range — from EcoBoost to GT to Mach 1 to GT350 to GT500. Same outer geometry as Ford’s factory unit.
Built To Order
Each trunk is laid up and finished after you order. Lead time runs 3-5 weeks. The upside: every panel is freshly cured and clear-coated, not sitting on a warehouse shelf for a year.

FAQ
Will it fit my GT500?
Yes. MAZ engineered the panel to share Ford’s outer fastback geometry across every S550 trim — EcoBoost, GT, Mach 1, GT350, and GT500 all use the same trunk profile. Bolts on identically.
Does it fit a convertible?
No. This is a fastback-only panel. The S550 convertible has a different rear deck design and requires a different trunk lid.
Do I need to flash the ECU?
No. This is a body panel swap that uses factory mounting + factory wiring. The ECU sees nothing different. No tuning, no DTCs, no surprises.
Why is the lead time 3-5 weeks?
Each trunk is laid up to order at MAZ rather than mass-produced and stocked. The trade-off is freshness — every panel ships with a fresh clear-coat instead of pulling one off a warehouse shelf that’s been sitting there.
Can I paint it?
Yes — though most customers run the carbon-and-clear look. If you do paint, the clear coat scuffs cleanly under primer. Pre-paint surface prep is the same as any modern composite panel.
Will the OE struts hold it open?
Yes. Carbon fiber is significantly lighter than the factory steel decklid, so the OEM gas struts have plenty of force to hold the trunk open with the new panel installed.
