Side Steps vs Two-Stair Specs
Step Structure
The AutoBull 6" Aluminum Running Boards feature a single, flat honeycomb anti-slip surface. This design offers a consistent, wide stepping area for easy entry. In contrast, the SOENBOO Two-Stair Running Boards use a dual-layer layout. This two-stair design includes a 6-inch drop-down step pad below the main bar. The lower step helps you reach vehicles with lift kits or oversized tires more comfortably. It also makes accessing the roof easier. The SOENBOO design provides an extra level of accessibility that the single-level AutoBull step does not offer.
Material Build
Material choice affects both weight and durability. The AutoBull side steps are constructed from high-quality aluminum. This material is naturally rust-resistant and contributes to a lighter overall product. The AutoBull unit weighs 34.2 pounds. The SOENBOO running boards are made from 2-millimeter-thick heavy-duty carbon steel. Steel is generally denser and heavier, which is reflected in the SOENBOO weight of 44 pounds. Both products use a black powder-coated finish to protect against corrosion and daily wear. The aluminum construction of the AutoBull may be preferable if you want to minimize added weight on your vehicle.
Weight Capacity
Load-bearing capability is a critical safety spec. The SOENBOO running boards explicitly state that each side can support up to 550 pounds. This high capacity is due to the heavy-duty carbon steel construction. The AutoBull product data does not list a specific weight capacity. While aluminum is strong, the lack of a published limit means you cannot verify if it matches the SOENBOO rating. If you frequently carry heavy loads or have larger passengers, the SOENBOO 550-pound rating provides a clear, verified safety margin that the AutoBull listing does not confirm.
Profile Height
The height of the step affects how close it sits to the truck body. The AutoBull side steps have a height spec of 2.1 inches. This low profile keeps the step close to the truck frame. The SOENBOO running boards list height variations, including 7.87 inches and 7.48 inches. These taller profiles are typical for two-stair designs to accommodate lift kits. The AutoBull 2.1-inch height is significantly lower than the SOENBOO options. If you prefer a sleeker look that stays closer to the vehicle body, the AutoBull offers a much lower profile.
Warranty Coverage
Manufacturer support varies between the two options. The AutoBull side steps include a 36-month warranty. This provides three years of coverage for defects or issues. The SOENBOO running boards offer a 1-year warranty. This is a standard one-year period for protection. The AutoBull warranty is three times longer than the SOENBOO coverage. If long-term protection is a priority for your purchase, the AutoBull 36-month warranty offers more peace of mind than the one-year limit provided by SOENBOO.

Frequently asked questions
Do side steps or two-stair running boards offer a wider foothold?
Both styles can provide a six-inch stepping surface, which is wide enough for secure footing. The AutoBull side step offers a single, flat honeycomb anti-slip surface for consistent support. The SOENBOO two-stair board also features a wide design, though its dual-layer layout changes how you place your feet. You should choose based on whether you prefer a single flat step or a two-level entry.
Which running board is better for a lifted truck?
Two-stair running boards are generally better for lifted trucks because they provide extra lift. The SOENBOO model supports lifted Colorado and Canyon Crew Cabs with a sturdy dual-step design. Side steps like the AutoBull unit sit lower to the ground. If your truck has a significant lift kit, the two-stair design helps you reach the cab floor more easily without straining.
Are aluminum side steps heavier than steel running boards?
Aluminum side steps are often lighter than steel alternatives. The AutoBull 6-inch aluminum running board weighs 34.2 pounds. This weight is manageable for installation and reduces stress on your truck's mounting points. Steel two-stair boards can be heavier, but data for the SOENBOO model lists a weight of 44 pounds. Lighter materials like aluminum can make handling easier during setup.
What is the difference between a side step and a two-stair board?
The main difference is the step structure. Side steps, like the AutoBull model, feature a single, flat surface. This creates a consistent, wide stepping area. Two-stair boards, such as the SOENBOO option, use a dual-layer layout. This design adds a second step level, which can help you reach higher vehicle beds. Your choice depends on whether you need extra height or a simpler profile.
Do these running boards fit double cab trucks?
Yes, both styles are available for double cab configurations. The AutoBull side step is specifically designed for the Toyota Tacoma Double Cab. The SOENBOO two-stair board fits the Chevy Colorado and GMC Canyon Crew Cab. You must verify your truck's cab size before purchasing. Each product is engineered to match the specific dimensions of its compatible vehicle model.
How wide is the stepping surface on these boards?
Both products offer a six-inch wide stepping surface. The AutoBull side step provides a 6-inch width for ample foot placement. The SOENBOO two-stair board also features a wide design to support your weight securely. A six-inch width is standard for many running boards and provides enough space for safe entry and exit. This width helps prevent your foot from slipping off the edge.
Which running board has a lower profile?
Side steps typically have a lower profile than two-stair boards. The AutoBull side step has a height of 2.1 inches. This low profile keeps the truck's appearance sleek and minimizes ground clearance issues. Two-stair boards sit higher to provide additional lift. If you want a subtle look that stays close to the truck body, the side step design is the better choice.
