What's wrong?
The floor frame rail on a 2013-2017 Supreme Kold King is part of the structure under the insulated body. It works with the floor frame cross members to support the floor, body, side mounting brackets, and refrigeration-related weight while the vehicle moves.
On affected Kold King vehicles, the weld between the floor frame rail and the cross members did not penetrate deeply enough. That weak weld joint allows the rail to start separating from the cross members. The source investigation also tied the condition to side mounting hardware brackets, the heavier insulated body, refrigeration equipment, body mounting hardware maintenance, and the removal of reinforcement gussets from the design before those gussets were added back in 2018.
Owners or service technicians can see warning signs before the structure fully separates. Look for weld separation, cross members pulling loose, a bent floor frame rail, or a body that appears to lean.

What's the safety risk?
A floor frame rail that detaches from the cross members can let the body separate from the chassis, increasing the risk of injury. Watch for weld separation, detaching cross members, a bent floor frame rail, or a leaning body, and schedule the repair soon if your VIN is included. Repair is free at any franchised Supreme dealer.
What should I do?
- Check your VIN to confirm your 2013-2017 Supreme Kold King is included in this recall.
- Contact a franchised Supreme dealer to schedule the free floor-frame reinforcement, which adds gussets to secure the floor frame rail to the cross members.
- Bring the recall notice if Supreme sent one. If not, reference recall number 18V256 when you call.
- Drive only as needed until the floor-frame repair is complete.
What happens at the repair
At the dealer, a Supreme technician installs reinforcement gussets to the floor frame where the frame rails attach to the cross members. That added reinforcement addresses the insufficient weld penetration described in recall 18V256. Parts and labor are free under the recall. If you've already paid for a related floor frame repair, Supreme's general reimbursement plan covers documented expenses. Ask Supreme customer service or the service desk how to submit the paperwork.
