Get your work truck or trailer ready for action with the PIERCE Light Duty Flat Bed Dump Kit, designed for working folks across the US who need solid, practical equipment. Built for after-market flatbeds or dump bodies, this universal kit lifts up to 10,000 lbs., making it a great fit for tasks like farming, property maintenance, or snow removal.

Dependable Power: Using a 12 Volt hydraulic pump (standard), this kit tilts your truck bed to a 45º angle in 30-90 seconds, letting you quickly offload materials like manure, firewood, or snow. Whether you’re clearing a driveway or spreading mulch on a farm, it saves time and keeps the job simple.  If you are needing more power, checkout the Medium Duty or Heavy Duty Kit.

Fits Many Setups: Made for bed lengths from 8’ to 12’, this kit works well for turning trailers into dump trailers or adding capability to flatbeds. Its strong scissor assembly and hydraulic system deliver steady lifting for everyday tasks.

Expert Installation Required: This kit calls for expert-level skills, including welding, mechanical, and electrical work. It includes a pre-assembled scissor assembly, hydraulic pump, and hardware, with our manual to walk you through. Reinforcing your truck bed is advised, and a professional’s help can make it smoother. Contact us at 940-538-5643 for support.

Tough and Trusted: Since 1976, PIERCE, a family-owned North Texas outfit, has made gear that stands up to hard work. Customers say the kit’s well-built and easy to use, cutting down effort with a quick button press.

FAQs (3)
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.
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.
What is the maximum lift capacity of the Light Duty Flat Bed Kit?
The kit itself is rated for up to 10,000 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.
