How to Secure Cargo in Your BYD Shark 6 Tub (Australian Guide, 2026)

The BYD Shark 6 makes a genuinely capable work and touring ute, but a tub full of unsecured gear is a problem waiting to happen. Loose cargo slides on braking and cornering — scratching and denting the tub, damaging your own tools and gear, and, most importantly, becoming a hazard to you and everyone behind you. Securing a load properly isn't just tidy; in Australia it's a legal requirement.

The good news: the Shark 6 gives you a solid starting point, and a few inexpensive additions cover almost any load. Here's how to secure your tub properly — from the factory anchor points to mats, nets, load bars and lockable storage.

Understanding the Shark 6 Tub and Load Limits

The Shark 6's tub is one of its strong points for tradies — it's wide enough to take a standard Australian pallet, with around 1,224 mm between the wheel arches. A durable spray-in bed liner is fitted as standard, and there are weather-shielded 230 V power outlets in the tub that run tools straight off the battery.

The number that trips people up is payload. The Shark 6's nominal payload is approximately 790 kg — but that's the total you can add anywhere on the vehicle, including passengers, accessories, anything in the cab, and the towball download when towing. It is not "how much you can pile in the tub." With a heavy kerb weight of around 2,710 kg against a 3,500 kg GVM, the Shark 6's payload is tighter than many diesel utes, so it pays to plan your load.

Your tub has four tie-down anchor points, one in each corner — your first line of defence for restraining a load. Check your handbook for the rated capacity of each point, and never rely on a single anchor for a heavy item.

Why Unsecured Cargo Damages the Tub

The factory spray-in liner is tough, but it isn't invincible. The real enemy isn't a single big impact — it's the repetitive stress of unsecured cargo sliding and grinding against the surface every time you brake, corner or hit a bump. Over time that wears and scratches the liner, and a heavy item sliding hard into a corner can chip or gouge it.

Beyond the tub itself, loose cargo damages whatever you're carrying and shifts the vehicle's balance. That's why a little restraint from day one is worth it: it protects the tub, your gear, and your handling — and keeps you on the right side of the load-restraint rules.

Method 1: Making the Most of the Factory Tie-Down Points

Your four factory anchor points are the foundation for restraining anything with weight. Using them correctly is non-negotiable.

The most common mistake is reaching for cheap, stretchy bungee cords. Those are only good for holding down a light tarp — they can't provide the tension needed to restrain heavy cargo. Use proper ratchet straps with a breaking strength suited to your load, and make sure they're rated and in good condition.

For a single heavy item like a generator or a large toolbox, use a cross-pattern method: run two straps diagonally across the item to form an "X". That resists both fore-aft and side-to-side movement far better than parallel straps.

Weight Distribution and Anchor Limits

Never concentrate an entire load on one anchor point. Spread the tension across at least two — preferably all four — for stability, and stay within each point's rated capacity as well as the vehicle's overall payload. Even a load that's under the payload limit can overload a single tie-down if it's all hanging off one corner.

Method 2: Tub Mats and Liners

A heavy-duty rubber tub mat is the most cost-effective upgrade, typically around A$120–180. It provides excellent friction to stop cargo sliding, installs in minutes with no permanent modification, and lifts out for cleaning. For most owners it's the single best-value bit of tub protection.

Drop-in plastic liners (typically A$400–600) sit over the factory liner for extra wall coverage, but they can trap grit and moisture underneath if not well fitted, and add weight that nibbles at your payload. If your factory spray-in liner is ever worn or damaged, a professional re-spray restores a permanent, textured, waterproof surface — just check the implications for your paint and corrosion warranty with your dealer first, as it bonds directly to the tub.

Method 3: Cargo Nets for Loose Items

Not every load is a single heavy block. For lots of smaller items — tool bags, camping gear, sports kit — a heavy-duty cargo net is indispensable. It stops a dozen small objects turning into projectiles under heavy braking.

For the Shark 6 tub, look for a net around 1.5 m × 2 m so you have enough to stretch over a bulky, uneven load and still reach all four anchor points. Nets with multiple hooks let you build a web of restraint across the whole tub.

Bungee cords have only a minor role here — light items under about 10 kg, like a rolled tarp. Never use them as the main restraint for anything heavy or hard. Combining a rubber tub mat (friction) with a cargo net (containment) is a simple, effective two-layer system for everyday loose loads.

Method 4: Load Bars and Dividers for Heavy Equipment

For tradies hauling heavy, specialised gear, straps and nets alone may not be enough. Adjustable load bars and divider systems add a more robust, organised layer.

Load bars (typically around A$150–250) telescope out to brace against the tub sides, forming a solid barrier that stops heavy items sliding forward into the cab under hard braking — essential for generators, compressors or heavy tool vaults. Custom divider systems, in plywood or purpose-made kits, let you compartmentalise the tub so delicate tools don't collide with raw materials.

Weight Distribution

For safe handling, aim to keep the bulk of the weight forward of the rear axle rather than piled at the tailgate. Load bars help enforce this by giving heavy items a fixed forward position. It's the same principle the load-restraint rules are built around: a stable, restrained, well-distributed load.

Method 5: Lockable Storage and Canopy Integration

Securing cargo isn't only about stopping it shifting — it's also about theft. Lockable storage boxes (commonly 100–200 litres) are popular, especially for tradies leaving tools in the vehicle. For real security, bolt the box to the tub floor or anchor it to the tie-down points so it can't simply be lifted out.

A hard canopy or roller cover is the ultimate step for security and weather protection, and many integrate with the Shark 6's central locking. If you're planning a canopy or roller cover, make sure your load bars and dividers won't foul the clamps or tracks.

Off-Road and Towing: Securing for the Long Haul

The forces on your cargo climb sharply once you leave the tarmac. A strap that feels tight on the driveway can work loose after a few kilometres of corrugated dirt, so off-road and long-distance trips call for a more redundant approach.

Towing also changes the maths. The Shark 6 is rated to tow 2,500 kg braked, but the towball download (up to 250 kg) counts against your ~790 kg payload — so the more you tow, the less you can carry in the tub. Weigh your typical load if you're anywhere near the limit.

The Double-Securing Method

For any long or rough trip, double up: lock the main cargo down with primary ratchet straps, then add a secondary restraint like a heavy-duty net over the top. If one system loosens, the other still holds. And plan inspection stops — pull over every 100 km or so to re-check strap tension and cargo position, because sustained vibration is very good at working straps loose.
