Finding a Professional
For your Dump Truck Kit Installation

If you choose not to do the hydraulic dump kit installation yourself, we have found body shops and machine/welder shops typically have the expertise required. Basically, any shop installing flat beds has the expertise.

The key to finding a reputable shop is research. While the following criteria does not guarantee a positive experience, it can help identify shops with experience and a history of good work.

Step 1

Research

  • Speak to colleagues and friends for recommendations.

  • The search engine is your next best option when looking for a local welder or fabricator with experience.

  • Search keywords along with your location to find one near you.

STEP 2

Credibility 

  • Check standing with organizations like the BBB.

  • Check for industry certifications like the ASE or ASA.

  • Check that the shop carries both Garage Liability and Garage Keepers Insurance.

15,000 dump kit

Excellent quality and easy to install. It does take some welding and problem solving to install but this is a universal kit so it was expected. I am very satisfied and the kit works flawlessly. Also was notified before delivery so if I didn’t have a way to unload it they could send a truck with a lift gate.
