Will Demco Air Force One Flat Tow Brake System DM54YV Work For 2024 Spartan K3 605 Chassis
Updated 11/03/2025 | Published 01/07/2025 >
Question:
Brandon here with Advanced Rv and Fleet Solutions. I am working on setting up a towed for one of my customers, and have a question about the demco part DM54YV. Which states that it is for Spartan K2 400 chassis factory equipped with safe haul. My customer has a 2024 Newmar King Aire with the Spartan K3 605 chassis. It has the air connection on the rear for the towed vehicle. So I am assuming that this will work for the K3 chassis as well. But I would like some verification on this if at all possible. thank you for your help!

Hello Brandon. Yes, the Demco Air Force One Flat Tow Brake System # DM54YV will work for the Spartan K3 Chassis as well. It is the same air force one prep kit on the K2 and K3 chassis so the brake system components would be the same.

Hey Brandon, how did things go using the Demco Air Force One system with the Spartan K3 chassis on your customer’s King Aire? It’d be great to hear how the setup turned out since others work with similar chassis combinations. Your update could make it easier for the next shop tackling the same setup.
