Not Here To F*ck Spiders

How preordering
actually works.
We're between print runs — here's exactly what happens when you reserve a pair now.
Reserve your pair
Pick a design and pop your details in. No payment required today — this just holds your spot.
We set it aside
Your name, address and contact details land straight in our order inbox so a pair gets held for you.
We're in touch
The moment your design lands — 30 days for Spiders, 2–3 months for the rest — we reach out to sort payment and delivery.
No. Reserving a preorder takes no payment at all — we just hold a pair against your name. We'll contact you to arrange payment and delivery once your order is actually ready to ship.
Not Here To F*ck Spiders is estimated at around 30 days. Southern Cross and the Filthy Flaps Wordmark are estimated at 2–3 months. These are our best current estimates, not guarantees — supplier and shipping timelines can shift.
Yes, any time before payment is taken — just message us on Instagram/TikTok @filthyflaps or through the contact form and we'll pull your hold.
Totally fine — reserve them together in one go. We'll reach out once everything's ready, or drop us a note if you'd rather we ship the faster item separately.
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.
