DOM vs. HREW Tubing in Rock Sliders: What You Need to Know

When it comes to off-road protection, rock sliders are a critical upgrade for any serious adventurer. Designed to shield your vehicle's vulnerable rocker panels from damage, they are especially useful when tackling rocky trails or challenging terrain. However, not all rock sliders are created equal, and one significant factor to consider is the type of tubing used—DOM (Drawn Over Mandrel) or HREW (Hot Rolled Electric Welded). Understanding the differences between these two materials can help you make an informed decision when choosing rock sliders for your vehicle.

What is DOM Tubing?

DOM, or Drawn Over Mandrel, tubing is a high-strength steel tubing made by cold-forming the material and passing it through a die, which improves its structural integrity. The result is tubing with a uniform wall thickness, superior strength, and excellent durability.

Key Features of DOM Tubing:

  1. Seamless Finish: Although it starts as welded tubing, the cold-drawing process eliminates visible weld seams, making it appear seamless.
  2. Superior Strength: DOM tubing is more resistant to bending and deformation due to its tighter tolerances and consistent wall thickness.
  3. Precision Engineering: The manufacturing process ensures high accuracy and dimensional consistency, making it ideal for critical applications.

What is HREW Tubing?

HREW, or Hot Rolled Electric Welded, tubing is made by rolling steel at high temperatures and welding the edges together to form a tube. While HREW is not as refined as DOM tubing, it is a cost-effective and practical solution for many applications.

Key Features of HREW Tubing:

  1. Visible Weld Seam: HREW tubing has a clearly defined weld seam, which can be a potential weak point in high-stress situations.
  2. Affordable Option: Its simpler manufacturing process makes HREW tubing a more economical choice.
  3. Good for Moderate Use: While not as strong as DOM, HREW is sufficient for most light-to-moderate off-road applications.


Comparing DOM and HREW Tubing for Rock Sliders

1. Strength and Durability

  • DOM Tubing: With its seamless finish and consistent wall thickness, DOM tubing offers superior strength and impact resistance. It can withstand heavy abuse from rocks and other obstacles, making it the preferred choice for extreme off-roaders.
  • HREW Tubing: While HREW tubing is still strong, it is less robust than DOM. The weld seam can act as a weak point under high-stress impacts, making it more suitable for light-to-moderate off-road conditions.

2. Cost

  • DOM Tubing: The advanced manufacturing process makes DOM tubing more expensive. However, for those who demand the highest level of performance and protection, the cost is often justified.
  • HREW Tubing: HREW tubing is a budget-friendly alternative that still provides adequate protection for less demanding applications.

3. Weight

  • DOM Tubing: Typically, DOM tubing is heavier due to its denser and stronger material. While this adds durability, it can slightly impact vehicle weight and fuel efficiency.
  • HREW Tubing: HREW tubing is lighter, which can be a benefit for vehicles where weight savings are a priority.

4. Application

  • DOM Tubing: Ideal for aggressive off-roading, rock crawling, and scenarios where maximum protection is essential.
  • HREW Tubing: Great for casual off-road enthusiasts who want functional rock sliders without breaking the bank.

Which Tubing is Best for Your Rock Sliders?

The choice between DOM and HREW tubing ultimately depends on your off-roading needs and budget.

  • Choose DOM Tubing if you frequently tackle extreme trails, rocky terrain, or other high-stress environments. Its superior strength and durability make it the go-to choice for serious off-roaders who need maximum protection and reliability.

  • Choose HREW Tubing if you’re a weekend warrior or prefer moderate off-roading. It’s an excellent choice for those who want dependable rock sliders without the premium price tag.
