The HULK is 100% designed, machined, formed, manufactured & assembled in the USA.
Weighing 80 lbs, the SWAG Off Road HULK Tubing Roller is a serious machine. Built in the USA, it features 4130 chromoly axles, a fully machined drive yoke, and a 2-ton bottle jack for smooth, controlled forming.
We offer 76 die sizes for round tube, pipe, and square tube—plus specialty dies for flat bar, handrail cap, rectangular tubing, and diamond-profile square tubing. Many are also available in Delrin, ideal for anodized or polished materials. All center drive dies are keyed to the axle for a secure, slip-free connection.
Most tubing rollers struggle with twist and repeatability—we’ve engineered around both. Our chromoly axles are machined to within ±.003” and centered with dual shaft collars to eliminate side play. The center drive yoke is fully machined from three pieces of ¾” thick steel for perfect squareness, keeping pressure straight and twist-free.
The built-in digital height gauge makes repeat bends easy. Zero the gauge at setup, roll to your desired radius, and log the settings for future jobs. No guesswork required.
Rather than a hard-to-turn screw jack, the HULK’s 2-ton bottle jack applies consistent downward force and stays centered over your material under load. All dies ride on roller bearings for smooth operation, and the 3-way handle can be upgraded with a Harbor Freight pipe threader (#62203) for hands-free power rolling.
Finished with a powder-coated steel frame, aluminum spacers, and stainless hardware, the HULK looks as good as it performs. Ships 90% assembled (base not included). Rolls round tubing and solid stock to a 12" radius; square and rectangular tube to ~36–48".
Mounting footprint: 30" x 8.625" (hole pattern: 29" x 7.625" on center). Each die set includes one drive and two non-drive rollers. We stock 1,000+ die sets and have nearly all sizes ready to ship.
Note: Recommended max wall thickness for Square Tube: 0.125"
Max wall thickness for round tube varies by size and material type. Contact us with any specific questions.
Note: Round Tube and Round Pipe are different materials. Please make sure to select the correct die for your material. If you have questions regarding the difference, please consult our FAQ page or send us an email at sales@swagoffroad.com

Customer Reviews
Purchased the roller to help make an art car/mutant vehicle for Burning Man. I needed to roll the 2 inch tubing to make a giant oval around the perimeter of the vehicle. The outer dimensions 23‘8“ long by 12‘6“ wide. The 2 inch tubing was needed to create a giant oval. The difficulty was the radius changed as you move the length of the tubing. I’ve included a video to show how I modified the roller. I added casters to the backside to be able to lay it over and remove the hydraulic jack and install the screw jack to allow me to adjust the pressure in the horizontal position.
The roller worked fantastically, the electric drive unit allowed me to make direction changes stop reverse. It was phenomenal.
The first project I used this for was a set of custom stainless guardrails for a client's sail boat. They wanted the material to match the existing rails, and the curve of the rail needed to match the curve of the hull of the boat, which was a compound radius. The fore and aft mounting points were also at different levels, so bends had to be made in the Z axis to allow for proper alignment with the mounting hardware. The hulk made this process as easy as it could possibly be and allowed me to get very consistent results between the two sides. The delrin dies are extremely durable, and they were well worth the cost as they helped maintain the mirror finish on the material, greatly reducing my labor hours for polishing. This tool paid for itself in the first job, and has led to many other jobs. This is a worthy investment.
Nolan,
Just wanted to reach out and saw the guardrails look great! Thanks so much for the photos and review!
Don't hesitate to reach out if any questions come up.
Thanks,

Haven't gotten to roll much tubing yet, but I appreciate the build quality and attention to detail. You can certainly buy more heavy duty machines complete with CNC automation, but this bender is about as good as you can get for a manual machine at that pricepoint. I can tell SWAG gives a damn about doing things as right as reasonable...right down to the faced bottom of the hydraulic jack to eliminate slop. I look forward to putting some more tube through it soon! Also - much prefer the solid gray to the older ones with the green pinstriping.
For the third time product was good, installation directions are terrible…

we build aluminum boats and this tool comes in handy for rolling some long bars and extrusion.
