Flips/Converter Dollies/Jeeps Trailers For Sale in Texas

Flips, converter dollies, and jeeps are specialized heavy haul trailer components used to distribute weight, add axle groups, and help a load meet bridge formula and state permitting requirements. Buyers in this category are usually matching one piece to an existing lowboy, detachable gooseneck, beam, or multi-axle configuration, so fitment matters as much as rated capacity. The first checkpoints are connection style, deck width compatibility, axle spacing, loaded ride height, and how the added axle group changes kingpin weight and overall axle loading. In Texas, where permit compliance and route planning are a daily part of heavy haul work, the right jeep or flip can make the difference between a legal move and a reworked configuration.

A flip axle, also called a flip or booster axle in some fleets, attaches at the rear of a lowboy or detachable trailer to add carrying capacity and spread the load over more axles. Common specs include single-axle and tandem-axle designs, steel construction, air ride suspension, drum brakes, and 255/70R22.5 rubber on steel or aluminum wheel packages. Pay close attention to axle spacing such as 54 or 54.5 inches, overall width, suspension brand, and whether the unit includes practical heavy haul details like D-rings, flag holders, stake pockets for wide load signs, limit chains, and additional lighting or strobe provisions. A flip that is properly matched to trailer height and neck geometry tracks better, loads more evenly, and reduces headaches at the scale house.

A jeep is installed between the tractor and the front of the trailer to shift weight off the truck drives and trailer neck onto an additional axle group. This setup is common on higher-capacity lowboy and platform configurations where front-end loading is the limiting factor. Converter dollies serve a different role, typically converting a semi-trailer into a full trailer or creating a specific towing arrangement, but the same buying logic applies: coupler style, drawbar dimensions, brake compatibility, ABS and lighting connections, suspension type, and legal configuration in the states where the equipment will run. On any of these units, buyers should confirm brake type, hub-pilot versus stud-pilot wheel setup, tire size uniformity, air and electrical hookups, and whether ride control features like leveling valves or lift provisions are needed for the intended loads.

Condition and compatibility are more important here than age alone. A newer flip or jeep still needs to match the trailer manufacturer’s dimensions and the permit strategy for the loads being hauled. Look closely at frame integrity, bushing and suspension wear, brake condition, tire match, light package, and signs of stress around connection points. If the application includes 55-ton to 60-ton class work or heavier, verify the rated capacity in the exact configuration you plan to use, not just the nominal model rating. Serious heavy haul buyers also check how quickly the unit can be pinned on, shimmed, or removed in the field, because uptime matters when a route, crane schedule, and escort window are all tied to the same move.
