Ducktail Spoilers

SHIROKAI ducktail spoilers are not another soft “stick-on aesthetic mod” from the early 2000s.

These things are aggressive on purpose.

Every spoiler is engineered from automotive-grade ABS plastic using full 3D scans of the real car for proper fitment and clean body lines. No universal nonsense. No fiberglass waves. No guessing where the edges should sit.

And no — we don’t trust your rear end to double-sided tape alone.

Real ducktail angle means real mounting hardware. Drill it properly. Bolt it properly. Send it properly.

Our lineup covers Ford Mustang S197 and S550, Dodge Challenger, Dodge Charger, Chevrolet Camaro 5th and 6th Gen, Corvette C5, BMW M4 F82, Dodge Durango, and Jeep Grand Cherokee Trackhawk.

A proper ducktail spoiler changes the entire rear silhouette of the car:
lower, wider, more planted, more aggressive — like the factory designers were too scared to push it this far.

Built for real roads, real speed, and real builds. Ships worldwide via UPS with full tracking and DDP delivery to the USA.
