Frequently Asked Questions


Newer truck beds 2018+ are manufactured differently that 2017 models. The main issue is the way the truck bed is fitted around the chassis. This rounded design causes the bed to not be able to be lifted unless the bed is several inches away from the bed. We are currently developing more kits for newer models.
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.
Many dump bed kit owners find themselves at a loss when it comes to installing the dump bed kit. This can be frustrating especially when your livelihood depends on it.  If you choose not to do the hydraulic dump bed kit installation yourself, we have found two types of businesses that typically have the expertise required to install the Pierce hydraulic dump kit. Take a look at the options:
  • Body shop
  • Machine shop/welder
Wondering how to find a professional and reputable body or machine shop? The key is a little research. Below we have done a bit of the foot work for you. While the following criteria does not guarantee a positive experience it can help identify shops with experience and a history of good work.
Body Shop – Criteria
1. Certifications – Is the shop is certified by one or more of the following? 2. Insurance – Does the shop carry the following insurance?
  • Garage Liability
  • Garage keepers
There are many resources for best practices when choosing the right body shop you can check out our favorites here: Angie’s list “Advice on finding a reputable body auto body shop” and The ASE “How to choose the right body shop”
Machine Shop – Criteria
Unlike body shops machine shops and fabricators often specialize in many different areas of business from construction, to car and trailer body welders to artists. Find one in your area by following these guidelines: 1. Research – Google is your best bet when looking for a local welder or fabricator with experience. Search keywords along with your location to find one near you. 2. Reputation – Speak to colleagues and friends for recommendations. Whether you choose to DIY dump kit installation or hire someone else Pierce offers complete instructions (download them here) and numerous videos to assist.
The cross member should be closest to the cab and the scissor should run to the rear of the truck.
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.
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.
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.
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 weldable Pierce Twist Lock (not included).

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

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.
With the dump kit for aftermarket flat beds, minimal welding is required. The hinges are welded and the rest of the installation process is bolted on.
The OEM kit is entirely bolt on with welding being optional.
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.”
With dump kits for OEM stock beds, raising your bed is unnecessary.
