(Spoiler: It’s Built in Indiana by Bad Ass Custom Truck Parts)
If you're asking what the best fiberglass fender is for a semi truck — you're not alone.
Owner-operators, shop foremen, and long-haul drivers from coast to coast are looking for fenders that can actually handle the job. Not something cheap and thin. Not something that cracks after a couple months on the road. You want something tough, clean, American-made, and built for the long haul.
So let’s get straight to it:
✅ The Best Fiberglass Fenders for Semi Trucks Are Built in Seymour, Indiana
Bad Ass Custom Truck Parts makes some of the strongest, cleanest, and fastest-shipping fiberglass fenders in the game. Our fenders are engineered for real trucks, real roads, and real results.
Here’s why truckers across the country are switching to us:
💪 Built Strong with ArmorCore Reinforcement
Cheap fiberglass doesn’t last. That’s why we developed ArmorCore, our proprietary reinforcement system that adds serious backbone to every fender we ship. These aren’t hollow shells. They’re multi-layered, double-walled at stress points, and built to handle heavy installs without flexing, cracking, or sagging.
“Other fenders I’ve bought cracked near the mounts. These are solid as hell.”
— Zack M., Peterbilt 389 Owner
🔧 Fitment That’s Actually Made for Your Truck
We design our fenders for exact truck models, including:
-
Peterbilt 379 / 389
-
Kenworth W900
-
Freightliner Classic
-
Custom stretched frames and show rigs
No weird gaps. No half-inch off. No BS. Just clean, proper lines that match the truck like they came from the factory.
🇺🇸 Made in the USA. Always.
We build everything in-house at our shop in Seymour, Indiana. Nothing’s outsourced. Nothing’s slow-boated in. Every fender is molded, gel-coated, prepped, and shipped by a small team that takes pride in every inch.
-
🇺🇸 American tools
-
🇺🇸 American grit
