2027 Load King Flips/Converter Dollies/Jeeps Trailers For Sale

Load King flips, converter dollies, and jeeps are purpose-built heavy-haul components used to fine-tune axle group configuration, distribute weight legally, and match a trailer to permit and route requirements. On a lowboy or detachable gooseneck setup, the right jeep or flip axle can be the difference between a workable haul plan and an expensive permitting problem. Buyers in this category are usually looking at axle count, axle spacing, rated capacity, overall width, and how the attachment integrates with an existing Load King trailer platform.

For Load King flip axles, common decision points include 55 ton versus 60 ton applications, 8 ft 6 in versus 9 ft deck width compatibility, and axle spacing in the mid-50-inch to 60-inch range. Sample specs in this category show configurations such as 54.5-inch spacing and 60-inch spacing, often paired with 255/70R22.5 or 275/70R22.5 tires. Suspension details matter because ride quality affects both load stability and frame stress. Heavy-haul buyers often look for air ride setups from suppliers like Hendrickson, independent leveling valves, suspension isolation kits, and outside aluminum wheels. D-rings, support brackets, and electrical connections such as 4-way plugs also matter because these pieces need to work cleanly with the trailer and any booster or rear axle group already in service.

A jeep, also called a load divider jeep, is typically used between the tractor and trailer to add axles and spread kingpin weight across more points of contact. A converter dolly serves a different role, commonly linking trailer combinations or supporting specific transport configurations, so the right choice depends on how the load is being built and permitted. Flip axles are generally the fastest way to add or remove carrying capacity at the rear of a heavy-haul trailer, especially when the operation needs flexibility across different jobs. Intermediate flip axles are another specialized option, often used with designated trailer series where the axle must sit within a specific position in the configuration rather than simply at the tail.

Before buying, confirm exact compatibility with the trailer series, neck style, connection hardware, suspension type, and legal axle spacing needed in the states where the trailer will run. It also pays to verify tire size, wheel package, brake spec, ride height, and whether the unit is intended for a dedicated trailer family such as a Load King Signature Series. Heavy-haul accessories are not universal, and small differences in width, mounting geometry, or electrical hookups can create fitment issues. For operators moving construction equipment, transformers, steel components, and other high-concentrated loads, a properly matched Load King flip, converter dolly, or jeep adds flexibility without compromising stability or permit compliance.
