Quad Cab vs Double Cab Specs
Cab Size Compatibility
The AutoBull running boards are specifically designed for the Quad Cab configuration, fitting Dodge Ram 1500 models from 2009 to 2018, the 2019-2024 1500 Classic, and Ram 2500 and 3500 quad cabs up to 2026. In contrast, the COMNOVA unit is built exclusively for the Double Cab layout, matching 2019-2026 Chevy Silverado and GMC Sierra 1500 models, as well as 2020-2026 2500HD and 3500HD double cabs. Both products explicitly exclude crew cab versions, ensuring a precise fit for their respective two-door-plus-half-door setups. This distinction is critical for proper installation and function.
Material Construction
Material choice affects both durability and maintenance. The AutoBull side steps utilize high-quality aluminum with a black powder-coated finish. This construction includes unique ABS plastic corner covers to protect the edges from impact. The aluminum body is rust-resistant and designed to withstand daily wear. The COMNOVA running boards are crafted from high-light stainless steel. This material is selected for its ability to resist salt spray corrosion and withstand UV radiation without discoloration. Stainless steel generally offers superior resistance to environmental elements compared to coated aluminum, making it a strong choice for harsh climates.
Step Width
Both products provide a 6-inch wide stepping surface, which is the industry standard for running boards. This width offers a secure footing for getting in and out of the truck bed. The AutoBull model features a honeycomb anti-slip design in the center of the step to enhance traction. The COMNOVA unit also provides a 6-inch wide step, relying on the inherent texture of the stainless steel for grip. Since both options deliver the same stepping width, neither has a clear advantage regarding the physical space available for your feet during entry or exit.
Profile Height
The height of the running board determines how much you need to lift your leg to enter the cab. The AutoBull Quad Cab steps have a profile height of 2.1 inches. The COMNOVA Double Cab steps sit slightly lower at 2 inches. This difference is minimal, but the lower profile of the COMNOVA unit might reduce the step-up effort slightly for some users. The AutoBull option is marginally higher, which could be preferred if you need a bit more clearance from the ground. Both heights are low enough to maintain a sleek look while providing necessary assistance.
Installation Design
Installation ease varies between the two designs. The AutoBull running boards come with mounting brackets and a screw pack for direct installation. The COMNOVA side steps feature an innovative slider design, allowing you to adjust the position of the step forward or backward on the vehicle. This adjustability can simplify the alignment process during installation, ensuring a perfect fit without the need for drilling. Both products are direct bolt-on systems that do not require drilling into the truck body, but the slider feature on the COMNOVA unit offers additional flexibility during the mounting process.

Frequently asked questions
Can I install double cab running boards on a quad cab truck?
No, the mounting points and bed lengths differ between configurations. The AutoBull steps are built for Quad Cab Dodge Rams, while the Comnova units fit Double Cab Silverados. Using the wrong size leads to poor fitment and potential safety issues. Always match the running board to your specific cab style.
What is the width difference between these running boards?
Both products offer a consistent 6-inch step width. The AutoBull model measures 6 inches wide, and the Comnova version is also 6 inches wide. This width provides ample footing for most drivers. The height differs slightly, with the AutoBull at 2.1 inches and the Comnova at 2 inches.
Which material is better for rust resistance?
Aluminum naturally resists rust better than stainless steel in wet conditions. The AutoBull Quad Cab steps use an aluminum body with a black finish. The Comnova Double Cab steps use stainless steel. Both are durable, but aluminum requires less maintenance to prevent corrosion over time.
Do these steps fit all Dodge Ram trucks?
No, they are specific to the Quad Cab configuration. The AutoBull steps fit Dodge Ram 1500, 2500, and 3500 models with a Quad Cab. They do not fit Double Cab or Crew Cab variants. Check your truck's cab size before purchasing to ensure proper compatibility.
How much do these running boards weigh?
Weight varies by material and size. The AutoBull Quad Cab steps weigh 36.4 pounds. The Comnova Double Cab steps weigh 45 pounds. The heavier stainless steel unit provides a solid feel but requires stronger mounting hardware. Consider your truck's bed length when calculating total weight.
What is the length of the AutoBull running boards?
The AutoBull Quad Cab steps are 77.4 inches long. This length matches the bed span of Dodge Ram Quad Cab models. The Comnova Double Cab steps are slightly longer at 78 inches. Ensure your truck bed matches these dimensions for a secure and flush installation.
Are these running boards automatic or manual?
Both products are manual side steps without automatic deployment features. The AutoBull and Comnova units require you to step on them to use. They lack sensors or motors for automatic extension. This makes them simpler to install and maintain compared to electronic alternatives.
Which truck brands are compatible with these steps?
The AutoBull steps are for Dodge Ram trucks. The Comnova steps are for Chevy Silverado and GMC Sierra models. You cannot swap them between brands due to different mounting systems. Identify your truck's manufacturer and cab size to select the correct running board.
