What Makes a Fender Bad Ass?
At Bad Ass Custom Truck Parts, we don’t slap our name on anything that doesn’t earn it. When we set out to build our own line of fiberglass semi truck fenders, we weren’t looking to blend in — we set out to raise the bar for what a real, road-ready fender should be.
Let’s be clear:
There’s a big difference between a fender and a Bad Ass Fender.
🧱 The Problem with Most Fiberglass Fenders
A lot of the semi truck fenders on the market today look the part — until they see real road time. Here’s what you’re typically getting:
-
Balsa wood cores that splinter under pressure
-
Thin fiberglass shells that flex, crack, or delaminate
-
Sloppy molds with rough edges and inconsistent thickness
-
Pre-drilled setups that limit your mounting or lighting options
-
Built to be replaced often, not to go the distance
They might save you a few bucks up front… but how many times do you want to replace the same fender?
🔥 What Real Truckers Actually Need
You’re not running a parade float. You’re hauling real freight, across long miles and unpredictable roads. You need gear that can:
-
Take a beating without falling apart
-
Handle vibration, impact, and temperature swings
-
Mount clean without hacks or shims
-
Look tough as hell while doing it
-
Let you customize without compromise
That’s what we built. That’s what makes a fender Bad Ass.
💪 The Bad Ass Difference
We didn’t build just another fiberglass fender — we engineered the one we wanted to run ourselves.
Here’s what separates our fenders from the rest of the pile:
✅ ArmorCore Structural Core
Forget balsa. Our ArmorCore inner structure delivers maximum strength without excess weight. It resists cracking, vibration fatigue, and gel coat failures — the exact issues that kill most fenders.
✅ Reinforced Multi-Layer Fiberglass
We use multiple layers of high-grade fiberglass, not thin skins. This means more rigidity, better shape retention, and long-term durability under stress.
✅ Sandable Gray Gel Coat
Every fender comes in a high-build gray gel coat that’s fully sandable and paint-ready. Whether you’re spraying to match your cab or leaving it raw and rugged, you’re in control.
✅ Custom Drill-Ready Design
No pre-drilled holes. That’s intentional. You get clean surfaces that drill smooth, letting you place lights, mounts, and accessories wherever you want — not where someone else guessed.
✅ Top or Bottom Mount Capable
Our fenders are designed for maximum mounting flexibility, giving you more control during install and better fitment across axle setups.
✅ Proudly Made in the USA
We manufacture right here in the U.S. because quality, pride, and accountability matter. Every fender reflects over 30 years of fiberglass manufacturing experience, backed by a warranty that actually means something.
⚔️ Bad Ass vs. The Rest

🎯 Built to Haul. Built to Last.
The Bad Ass Fiberglass Semi Fender wasn’t made for showrooms — it was made for long hauls, tough loads, and drivers who give a damn about their truck.
So next time you’re staring at another cracked fender or a cheap fix, ask yourself:
Do I want a throwaway part?
Or do I want one that’s built like a Bad Ass?
