Poly Block Off-Road Override Trailer Coupling – 2000kg Rated (Premium Dacromet Coating)
Equip your off-road setup to handle the relentless punishment of corrugated tracks, washouts, and steep technical terrain. Engineered specifically for 4×4 camper trailers, hybrid caravans, and heavy-duty box trailers utilizing mechanical override brakes, this 2-Tonne Poly Block Override Coupling delivers uninhibited multi-axis articulation that traditional 50mm ball hitches simply cannot match. Treated with an advanced Dacromet industrial coating, it provides elite protection against salt air, coastal corrosion, and harsh highway debris.
    • 2000kg (2T) ATM Capacity: Heavy-duty load-rated towing casting for mid-sized overlanding configurations.
    • Elite 360° & 70° Oscillation: Full horizontal pivot rotation and 70 degrees of vertical clearance prevent dangerous binding or snapping over sudden washouts.
    • Premium Dacromet Shielding: Superior protection against aggressive rust and oxidation compared to standard zinc plating.
    • Dual Grease Nipples: Equipped with two integrated, high-access grease nipples to ensure easy on-the-go maintenance and smooth, noise-free pivot rotation.
    • Universal 4-Hole Fitment: Standardised 185mm x 55mm mounting centres with clean 13.5mm bolt hole profiles drop cleanly onto standard override braking bodies.
    • Fully Road Legal: Complies with Australian Standards AS4177.3 and carries Component Type Approval # CTA-060308.

About Poly Block Off Road Coupling 2000kg Rated Dacromet Coated Trailer CTA-060308
2000kg Poly Block Off-Road Trailer Coupling (4-Hole — SKU: PBOC)
Conquer the toughest Australian off-road tracks with extreme towing articulation. This heavy-duty 2000kg Poly Block Off-Road Coupling (PBOC) is purpose-built to replace standard, restrictive 50mm ball couplings on camper trailers, box trailers, and off-road boat trailers up to 2 Tonnes.
Unlike traditional vehicle couplers that bind up, groan, or risk snapping over extreme terrain, this poly block configuration provides full multi-axis rotation. It allows your trailer to pitch, roll, and yawn smoothly behind your 4WD over deep washouts, steep river crossings, and rugged outback terrain.
Why Upgrade to this PBOC Off-Road Coupling?
    • 360° Multi-Directional Movement: Engineered with a heavy-duty urethane poly block pivot point that allows maximum horizontal and vertical travel without structural binding or trailer hitch strain.
    • Direct-Fit 4-Hole Base: Designed with an industry-standard 4-bolt mounting pattern (184mm x 54mm centres). This serves as a seamless, direct bolt-on retrofit for worn-out mechanical or standard override couplings on your trailer’s A-frame drawbar.
    • Treg & Trigg Style Compatibility: Slides directly over standard 19mm drop-pins and vehicle-side car adaptors, making it a highly convenient option if you already utilize a poly-block towing network across multiple vehicles.
    • Heavy-Duty Corrosion Defense: Cast from premium solid steel and finished with a robust, thick zinc plating. This rust-resistant shield prevents metal binding, seizure, and structural pitting in harsh coastal beach environments and deep mud tracks.
    • Silent, Shock-Absorbing Towing: The internal poly element absorbs intense highway vibrations and off-road shunting. This stops annoying towbar rattles and drastically reduces wear on your vehicle’s chassis and towbar tongue assembly.

Technical Specifications:
    • Part Number / SKU: PBOC
    • Maximum Towing Capacity: 2,000kg (2 Tonne) ATM
    • Mounting Hole Pattern: Industry-Standard 4-Hole (184mm x 54mm bolt centres)
