Built by people
who hate
clean utes.
Filthy Flaps started because every mudflap on the market was either flimsy, forgettable, or trying way too hard to look tough. We wanted something with actual attitude — flaps that hold up to real Aussie dirt and make people laugh (or wince) at the servo.
Every set is moulded from TPE (Thermoplastic Elastomer) — a genuinely good balance of stiffness and flexibility, chosen because it flexes across a wide temperature range, resists cracking on corrugations, and holds its UV resistance instead of chalking out in the sun. It's also recyclable. Not imported off-the-shelf stock — if it cracks, fades, or falls off doing its job, we'll sort it.
Bolts on to
most rigs.
Universal mounting kit included with every set. Model-specific pre-cut profiles are rolling out — flick us your rig and we'll confirm before you order.
