Finish the Build: Severe Duty Accessories
Bumpers, winches, lockers, beadlocks, sway bars, spacers and tanks — engineered for the same trucks we build conversions for, and available on their own.
Built to Bolt Onto Work Trucks
Your truck is more than a tool — it reflects your work. Every accessory here is specified for severe-duty service on Ford F-250 through F-600, Ram 4500/5500 and Chevrolet 4500-6500 chassis, whether you run a DBL conversion or a factory truck.
Custom DBL Body Guard Front Bumper
Steel bumpers built by a Texas manufacturer with tens of thousands of units in the field, cut to DBL fender lines so the front end matches a super single conversion instead of hanging inside it.
- Custom manufactured to DBL fender lines: 7.5" wider and 4.5" shorter than a standard F-250 bumper
- Tough steel construction that handles challenging conditions
- Shields the front end from damage on the job and on the trail
- Winch-ready with light cutouts, recovery points and grille guard options
- Rugged design gives the truck an aggressive appearance

- Improves traction, control and stability on rough terrain
- Built for serious off-road and heavy-duty applications, not light-truck use
- Industry-leading pin sizes and solenoid capacity on Pro 80 applications
- Pairs with our 6:17 gear conversions and severe duty axles

Forged Aluminum Wheels & Internal Double Beadlocks
Internal double beadlocks clamp the tire bead from inside the wheel, so you can air down for traction without unseating a tire — and keep running if you lose pressure.
- Keeps tires secure on the rim even at low pressures
- Durable forged construction that withstands extreme conditions
- Runflat and rubber beadlock inserts available for mission-critical use
- Ideal for off-road, expedition and heavy-duty driving
- Built into our 8,400 lb rated super single wheels — CTIS compatible

Sway Bars & Severe Duty End Links
Factory sway bar end links are the first thing to fail on a lifted, heavily loaded truck. Ours are machined heavier, and the bars themselves are 30% stronger than factory with a 45° turning radius up front.
