A dump bed kit is a truck conversion that enables the bed of your truck to dump its load. Turning your truck into a workhorse overnight. 

The conversion utilizes a hydraulic hoist, effectively turning your truck into a dump truck.  The dump bed kit conversions is easy and inexpensive. PIERCE dump hoist kits are DIY, and start out around $1,200.

The kit comes in the following options Stock Bed, Light Duty and Medium Duty. The Stock Bed kit does not alter the look of your truck. The Light Duty and Medium Duty kits require the use of a new bed (flat or dump style). Whether it’s a backyard project or a valuable asset on the job site, Pierce dump bed kits are up to the task

Dump Kit FAQs

Q. Which hydraulic dump kit will fit my truck?

Choosing your dump kit requires that you know information such as the make, model and year of your truck. You can read our “Which dump kit will fit my truck” article to determine whether the Stock Bed, Light Duty, or Medium Duty Dump Bed Kit is best for you.

Q. Will I have to raise my bed?

With the Stock Bed Kit raising your bed is unnecesary. With the PIERCE Light Duty and Medium Duty hydraulic dump bed kits you will be using a flat bed or dump bed and this requires raising your bed 2.5 to 3 inches depending on the truck.

Q. How much welding/cutting is involved?

With the Stock Bed kit, minimal welding is required. The hinges are welded and the rest of the installation process is bolt on. With the Light Duty and Medium Duty dump hoist kits, 70% of the installation requires welding and the remainder is bolt on.

Q. Do you have an install shop in my area?

Pierce does not currently license installers. The dump kit comes with instructions and we provide instructional videos here. Please note: the Light Duty and Medium Duty kits will require some welding skills. We have found some best practices when choosing someone to install the dump kit. Click to read “Who can install your dump kit.”

Q. Do I have to have overhang?

You do not have to have overhang, but mounting the rear hinges is much easier when you have at least 6 inches of overhang. Also, REMEMBER less overhang = less capacity. The suggested overhangs in the manual are necessary to achieve the specified capacity. Visit the Light Duty and Medium Duty overhang table here. 

Q. How much overhang do I need?

The amount of overhang you choose directly affects your capacity. Refer to the chart in the manual for further information.

Q. How long is the install time?

With experience a dump kit installation typically takes 12 to 16 hours. If this is your first time, expect to spend at least 16 to 24 hours of work to complete your dump kit conversion.

Q. Can I pull a trailer with the dump hoist kit?

A gooseneck trailer SHOULD NOT be pulled with a truck that has a converted dump bed.

A bumper pulled trailer can be used; however, you will want to pin the front of the bed down (this is not currently supplied with the kit) with a Pierce twist lock plunger with threads works great for this. You can also find the weldable twist lock here.

NOTE:  On the Stock Bed kit you will have to both drop down and deepen the receiver 2 – 3 inches towards the cab.

Q. Can I shorten the hinge pieces?

Yes, the pieces are made extra long for a universal application. Be sure you do not cut into the brace of the hinge as this will compromise the integrity of the hinges.

Q. How do I relocate the fuel filler neck?

The Stock Bed kit comes with a fuel kit – a 90° elbow to redirect the fuel line (which is optional) and a fuel bracket that bolts to the side of the frame. You must ensure a downhill flow to avoid fuel spillage during fueling.

Q. Where do I mount the pump?

You can mount the pump at any location you desire as long as it is clear of any moving parts. Most installations have the pump mounted to the side of the frame behind the truck cab. Some people have even mounted it inside the cab.

Q. Which way does my scissor need to run on the truck?

The cross member should be closest to the cab and the scissor should run to the rear of the truck.

Dump Bed Kit Installation

Read First
  • Read the installation manual before proceeding.
  • Disconnect the vehicle battery before welding.
  • All wires must be supported by the truck frame. Wires connected to the bed are hazardous.
  • When raising the bed, use an overhead hoist or body props. Be aware, injury can occur if the bed is not properly secured. Never leave the bed unattended when in the raised by a hoist or body props.
  • Only weld at the rear of the chassis frame. Do not weld anywhere forward of the rear spring hangers in order to prevent cracks from developing in the frame and possible weak spots during the welding process.
  • Never exceed the weight limit of your equipment. Refer to your vehicle’s owner’s manual for more information.
  • Install a safety cut-off switch to prevent electrical shorts.
  • Secure all electrical lines every 12″ – 16″ with zip ties.
  • Installation of the 200 amp breaker is required.

Following these best practices will ensure accurate and safe installation of your Pierce hydraulic dump bed kit. Good luck and happy installing!

Dump Bed Kit Maintenance

Maintaining your hydraulic dump bed kit is essential to running your equipment. Just follow this handy maintenance checklist to keep your dump bed kit in working order. We suggest going through this checklist at least once a year. A good time is at the beginning of spring or before the first frost.

Step 1 – Check all terminals for corrosion. If corrosion exists eliminate with a wire brush or chemical removal. In extreme cases you may need to replace wiring systems.

Step 2 – Inspect power cables for any cracking or breaks that could short out. Over time cables dry rot and break so it’s important to maintain and replace your cable when necessary.

Step 3 – Check your hydraulic fluid. If your hydraulic fluid is milky, cloudy, or freezes you could have water in your system. Click here to read “Pump Maintenance: Flushing the Hydraulic System” for complete instructions.

Step 4 – Apply grease at all grease point locations. *Only on Light Duty and Medium Duty  PIERCE dump kits

Step 5 – Check the hydraulic dump bed kit for any bent or broken pieces that may need to be replaced, this could occur from overloading.

Taking the steps to maintain your PIERCE dump hoist kit keeps your equipment in working order and adds to the life of the product.
