Upgrade your work truck or trailer with the PIERCE Medium Duty Flat Bed Dump Kit, built for hardworking folks across the US who need reliable, efficient gear. Made for after-market flatbeds or dump bodies, this universal kit handles up to 15,000 lbs., perfect for jobs like landscaping, construction, or cemetery upkeep.

Strong Performance: With a 12 Volt hydraulic pump that comes standard, this kit lifts your truck bed to a 45º angle in 30-90 seconds, making quick work of unloading dirt, gravel, or mulch. Whether you’re dumping in a field or working in a quiet cemetery, it gets the job done fast while saving your energy. If the Medium Duty is more than you need, checkout the Light Duty Kit. If more power is needed, take a look at our Heavy Duty Kit.

Wide Fit: Works with bed lengths from 8’ to 12’, this kit is great for turning trailers into dump trailers or improving flatbeds. Its tough scissor assembly delivers steady power for heavy tasks.

Expert Installation Needed: This kit requires expert-level skills, including welding, mechanical, and electrical know-how. It comes with a pre-assembled scissor assembly, hydraulic pump, and almost all necessary hardware, plus our manual. Strengthening your truck bed is a good idea, and a pro’s help might be useful. Call our team at 940-538-5643 for advice.

How involved is the installation of the Flat Bed Dump Kit?

Rated as an expert-level install, this kit requires advanced skills, including welding and potential modifications to your truck or trailer. For optimal performance, we recommend you reinforce your truck bed and consider professional assistance. Contact us for advice on your best options.

Will I be able to tow a trailer with this dump kit installed?

Towing is only permitted with frame-mounted receiver hitches. Gooseneck hitches are not compatible and will have to be removed before installing the dump kit.

What is the maximum lift capacity of the Medium Duty Flat Bed Kit?

The kit itself is rated for up to 15,000 lbs. However, there are several factors you need to consider. The first is the capacity of your truck or dump body. You do not want to exceed that under any circumstances. The second is the bed length vs the overhang. We provide charts for each kit so you can get an idea of your bed length vs how much overhang you will need to get the required lifting capacity.
