FAQs (3)
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 Heavy Duty Flat Bed Kit?
The kit itself is rated for up to 20,000 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.
