Learn more Tow Bar Tongue vs 50x50mm Receiver Understanding Your Mounting Interface Not all tow bars are the same. The Tow Bar Tongue Pivot Base (PBT) is designed specifically for the flat tongue plate that your tow ball normally bolts to. If your vehicle has a square 50x50mm receiver tube instead, you need our standard Pivot Base System. This Product (PBT) Mounts To Standard 50mm tow bar tongue plate (where the tow ball normally sits) Connection High-tensile bolt and nut assembly replaces the tow ball entirely Best For Vehicles with a tow-ball tongue: Toyota Camry, Corolla, Ford Territory (tongue type), older sedans and wagons 50x50mm Pivot Base System Mounts To Square 50x50mm hitch receiver tube (the hollow square box on SUVs and 4WDs) Connection Slides into the receiver with iSi Hitch Stabiliser for zero-wobble performance Best For SUVs, 4WDs, utes and most modern vehicles with a standard hitch receiver Manufactured For Performance The PBT Key Features Same engineering philosophy as our 50x50mm pivot base system, purpose-manufactured for the tow bar tongue interface. High-Tensile Bolt Assembly The tow ball is removed entirely and replaced with a precision bolt and nut system that delivers uncompromised strength and stability under load. Anti-Rotation Stops Stabiliser stops prevent the carrier from rotating during emergency braking or sharp manoeuvres. The rack stays exactly where you installed it. True Pivot Functionality The entire carrier pivots down in seconds for full rear vehicle access, even with bikes loaded. Tailgates, boots and hatches remain fully functional. 2 and 4 Bike Compatible Works seamlessly with all iSi two and four bicycle carrier assemblies and expansion packs. One mounting interface, full system compatibility. Removable Tow Bar Tongue? If your tow bar tongue is the removable type (slides into a receiver and locks with a pin), we recommend adding our Hitch Stabiliser System to eliminate any movement between the tongue and the receiver tube. This keeps the entire assembly solid and wobble-free. Lifetime Warranty 50mm Tongue Compatible Made In Melbourne 30 Day Returns Not sure which pivot base you need?
