Ultra-Fab’s wider-application stabilizer accommodates the larger axle spacing common on models like Bullet, La Crosse, Prime Time, Passport, and North Trail trailers. The one-piece chock expands from a compact 4.5 inches for travel to a full 10 inches when deployed under your RV.

Like the smaller model, this version applies opposing force to tandem tires, preventing roll on any slope. Heavy-duty steel with rust-inhibitive coating, textured grip handle, and optional padlock compatibility offer durability and security for extended parking or storage.
