What's included+
  • A set of two Flappies — one for each side of your vehicle.
  • Nuts, bolts and washers for easy installation.

Note: the design may vary slightly based on the size selected, to keep the best fit and visual impact.

Fitment tip+

No two rigs are the same, so a little measuring is part of the process. Trust it — it's worth it.

Tray-back utes — Measure the width inside the guards so the Flappies follow the natural shape of your setup, then pick the length that suits your look and coverage. Legal rule of thumb: the bottom edge of the flap should sit no higher than one third of the distance back to the centre of the rear axle — worth a look at your state’s rules if you’re cutting it fine.
Most 4WD wagons and utes — Flappie Frames are designed to fit the majority of vehicles. Once the frames are on, swapping Flappies is quick and easy.
Standard cars — We’ve got something cooking in the background — follow along for the announcement.
Not sure? — We’re always happy to help — send through your measurements or questions and we’ll make sure you get the right fit first go.
What it's made of+

Heavy-duty, flexible flap material that shrugs off mud, rocks and UV. Full-colour print, sealed edge to edge — it'll outlast cheap plastic flaps and bumper stickers. Apocalypse survival: unconfirmed.

"Absolutely stoked with how these sick puppies turned out. Matched the vibe perfectly and really set the look off. Only been on the D-Max a few hours, but you can tell they’re built to last."
