Patented RV Wheel Well Tire Blowout Protection
Damage from blowouts is now a choice. Bolted directly to your axle, RV-DE-FENDER® contains explosive blowouts and redirects flying rubber tread away from your trailer frame, subfloor, and plumbing.
Wheel Well De-Fender (Flagship) Designed for Extreme Travel
The world's premier tire blowout protection system. Heavy-gauge cold rolled steel containment arches that protect your RV, family, and vacation from catastrophic tire explosion damage.

See What a 65 MPH Blowout Actually Does to Your RV
Factory plastic fender skirts provide zero resistance against delaminated steel-belted tires. Explore real roadside case files below and see why RV-DE-FENDER® is essential armor.
Subfloor & Skirting Rupture

At 65 MPH, the steel belt delaminated and acted like a radial saw blade against the unreinforced underbelly, violently distorting the aluminum siding and ripping structural cross-members.
Buckled Metal Skirting
High-speed tire tread peeled back the lower aluminum trim like a tin can.
Coroplast Underbelly Shredded
Insulation, wiring harness, and tank support framing exposed to road debris.
Subfloor Frame Impact
Upward impact nearly pushed through into the living room flooring.
Zero welding required · Bolt-on for straight axles with leaf springs & drum brakes
Without RV-DE-FENDER®
A single blown trailer tire routinely costs $5,000+ in siding, wiring, plumbing, and slide-out repairs, plus weeks or months waiting for RV dealership parts.
With RV-DE-FENDER®
Tread impact is deflected by 14-gauge steel armor. Your RV stays intact. Swap to your spare tire on the shoulder and safely continue your family journey.

What RV Owners Are Saying
“Saved my fifth wheel from a G-rated blowout”
Had a catastrophic blowout on I-10 doing 70 mph. The RV-DE-FENDER contained every shred of tread — my subfloor, plumbing, and slide wiring were untouched. Replaced the tire and kept rolling. This product paid for itself in one incident.

“Worth every penny for peace of mind”
We full-time in a tandem axle travel trailer and the install took about an hour per side. No drilling, no welding. Zack's video walkthrough made it foolproof. We tow through the Rockies constantly and finally feel protected.

“Single axle toy hauler, perfect fit”
Was skeptical a single-axle rig needed this, but a buddy lost a whole side of his trailer to a blowout. The fitment team confirmed my specs and shipping was fast. Clean bolt-on install. Highly recommend.

“American-made and it shows”
The steel quality is immediately obvious — heavy gauge, clean laser cuts, perfect powder coat. You can tell this isn't cheap imported junk. The mounting plates bolted right up to my axle flange.

“Triple axle fifth wheel, flawless”
Three axles means six fenders and six chances for disaster. RV-DE-FENDER built a custom triple kit for my rig. Fitment was dead-on. Towed 2,400 miles since install with zero issues. Best RV upgrade I've made.

“Insurance against the inevitable”
After watching Zack's blowout videos I couldn't unsee it. My single-axle camper is my home away from home. Install was straightforward and the customer service team answered every fitment question. Zero regrets.

“Towed 3,000 miles through the Rockies — not a scratch”
We full-time in a 38ft fifth wheel and run mountain passes all summer. After a buddy lost his whole undercarriage to a blowout we ordered the triple-axle kit. Install was clean bolt-on, no drilling, no welding. Three thousand miles later the powder coat still looks factory.

“14-ply G-rated tire let go at 72 MPH in West Texas heat”
Tread separated in West Texas heat. Heard the loud pop, but zero subfloor damage! The cold rolled steel arch took the beating and kept the tire from wiping out my hydraulic lines and slide wiring. Worth every single penny.

“No more white-knuckling every pothole”
We tow a tandem axle all over the Pacific Northwest and used to dread every tire. Since bolting on RV-DE-FENDER we actually relax on long hauls. The build quality is outstanding and the powder coat has held up through a full muddy season.

“Best money I've spent on my toy hauler”
Single-axle setup and I tow toys up north every weekend. The fitment crew double-checked my hub spacing before shipping and it bolted right up. Feels like factory equipment. Wish I'd bought it years ago.

“Saved our entire spring break trip”
Blowout on I-26 heading to the mountains. Pulled over, swapped the tire, and kept driving to our campsite. No damage to the slide floor, no ripped wiring. RV-DE-FENDER literally saved our family vacation.

“Heavy-duty and honestly engineered”
You can feel the difference the moment you unbox it. Heavy cold-rolled steel, clean welds, perfect mounting hardware. Our triple-axle fifth wheel is finally protected the way it should have been from the factory.
