#2616 GM Bed Support Bracket Kit

#2616 GM Bed Support Bracket Kit

The concept of a hitch without a Four Point (4P) Rail Mounted system with supporting brackets attached to the frame, leaves something to be desired.  A fully-supported mounting system must be in place and Single Point (1P) mounting systems need every bit, if not more, of that frame support to prevent damage to the truck bed over time.  A dispersed load weight needs to go somewhere, and in most 1P systems, that weight is distributed to the underbed cross sills (or crossmembers) that provide support the truck bed on the frame.

This issue is not specific to the SuperLite #2600 or #3900 Super 5th.  We are, however, the only company that performed the necessary testing to discover the need for it and requires additional frame support to maintain a higher weight rating. With proper stress testing, we found it necessary to create no-drill brackets that would provide the metal-to-metal, downward support that we needed to maintain a solid 20K rating.

Ford and Ram's cross sills are located underneath, or very close to, each of the #2600’s Bed Saver Rails, but GM manufactured their cross sills unevenly spaced under the bed, and are located too far away from the hitch to provide proper support for 20K towing.

A towing system includes each vehicle and component involved in towing. Each item in your towing system has a capacity or weight rating.  You trailer has a Gross Vehicle Weight Rating, or GVWR.  Your truck has a tow capacity, payload capacity, and possibly more. In addition, your fifth wheel hitch has a weight rating.  This weight rating must be at, or above, the GVWR of your trailer for you to tow safely.  In addition, if your truck can tow larger loads (has a larger capacity) than the rating of your hitch, your system is only safe to tow loads at the lower rating, that of the hitch.

Your mounting kit also has a weight rating, just like your fifth wheel hitch. Many times, these rating are designed to match. But, this is not always the case. Your mounting kit may be higher rated then your fifth wheel hitch, but it also could be lower depending on the components involved.  The lowest rating of any one component in the system becomes the rating of the entire system. If your mounting kit is rated to 18,000 lbs., and your hitch is rated at 24,000 lbs., the weight rating of the entire system will not be above 18,000 lbs.  Other components in the system could lower the actual system rating further.

It is the end users responsibility to ensure a safe towing experience. To this end, it is your responsibility to ensure that the truck, trailer, hitching components, and all other items involved are rated or have a capacity sufficient for the loads involved.
