Compatibility:
Designed specifically for use with the BGT4X4 Backbone Mounting System.
The bars can be installed above or below the backbone brackets, depending on the clearance and overall height required for your setup.
If you're unsure whether these bars will work with your existing roof setup or accessory, contact us before ordering and we'll happily help confirm compatibility.
Load Information:
Each cross bar has a 70kg load rating.
This does not mean four bars provide a 280kg permissible vehicle roof load.
Your vehicle's applicable roof load limit and the load limits of the backbone, mounting system and fitted accessories still apply and must not be exceeded. The weight of the backbone, cross bars and any fitted accessories also needs to be included when calculating your total roof load.
Loads must be appropriately distributed and securely mounted.
- 4 × 1120mm Aluminium Cross Bars
Mounting hardware is not included. The hardware supplied with your BGT4X4 Backbone Mounting System can be used.
Do these come with the BGT4X4 Backbone Mounting System?
No. This listing is for the set of 4 aluminium cross bars only. The Backbone Mounting System is sold separately.
How much does the complete setup weigh?
The 4 cross bars weigh 4.8kg total. When paired with our aluminium Pajero Backbone Mounting System, the complete setup weighs just 8.9kg.
Can I mount a rooftop tent to these?
Yes. When fitted to our backbone, the distance from the front to rear cross bar is approximately 1830mm. Make sure your rooftop tent rails are compatible with this spacing.
Can the bars be mounted underneath the backbone?
Yes. The cross bars can be mounted above or below the backbone brackets depending on your setup.
Will these fit other backbone systems?
They may, depending on the dimensions and mounting configuration. The bars are 1120mm long, so we recommend checking your setup before purchasing.
What is the load rating?
Each cross bar is rated to 70kg. Your vehicle's applicable roof load limit must still be followed and includes the weight of the roof system, accessories and cargo.
These cross bars are covered by a 2-year warranty against manufacturing defects in materials and workmanship.
The warranty does not cover damage resulting from:
- Incorrect installation or modification
- Exceeding applicable vehicle, roof rack or accessory load limits
- Overloading or uneven distribution of loads
- Incorrectly secured loads or accessories
- Failure to check and maintain mounting hardware and bolt tension
- Continued use where mounting hardware has become loose
- Damage caused by severe impacts, accidents or misuse
- Use in conditions or with loads beyond the product's intended application
- Normal wear and tear or cosmetic damage
Important: Roof rack systems are subject to increased vibration and movement when travelling on corrugated or off-road surfaces. Mounting hardware should be checked regularly and re-tightened as required, particularly after initial installation and after travelling on rough roads.
Damage caused by loose mounting hardware, overloading or continued use with loose fasteners is not considered a manufacturing defect.
A lighter, slimmer way to run a backbone roof setup - exclusive to BGT4X4.
Our slimline aluminium cross bars for backbone systems were developed to give you an alternative to the weight and bulk of a traditional full roof platform. We were the first to offer this style of setup, and it remains exclusive to BGT4X4.
This complete set includes 4 × 1120mm cross bars, made from heavy-duty 4mm aluminium and weighing just 1.2kg each. Pair all four with our aluminium backbone and your complete roof setup weighs only 8.9kg, leaving more of your available roof load for the gear you actually want to carry.
The slimline design keeps your setup low, clean and lightweight, while three accessory slots per side give you plenty of mounting options for compatible rooftop tents, awnings, recovery boards and touring gear.
The bars can also be mounted above or below the backbone brackets, giving you flexibility depending on the clearance and overall height you want.
For those who don't need the size and weight of a full platform, it's a clean, versatile way to get the carrying capability you need without unnecessary weight on the roof.
Exclusive to BGT4X4 • 4mm aluminium • Set of 4 • Only 8.9kg with backbone • Slimline design

Just did an overnight camping trip with the new backbone and cross bars. Really great product and easily had the rtt and awning hanging on them. Couldn't recommend them highly enough.
Hey Jared! Love the setup it looks great mate! Thanks for the review, appreciate it.
Shipping was super quick, came packaged well and quality feels really good. Mounted a kings grand tourer lite rooftop tent to the crossbars which was extremely easy. Always rate any products from BGT4X4 very highly.
Hi Liam, thank you for your fantastic review! We're glad you're satisfied with the cross bars and that the installation was smooth. We appreciate your support for BGT4X4!
Hi what’s the dimensions of the bar LxWxH if mounted on top what is the clearance at it’s lowest point from the middle of the roof to underside of the bar thanks
1200x40x20. Mounted at bottom is 10mm from roof. On top of backbone has a 34mm gap. RTT setups need to go on top, bottom is more for people running awnings or anything under 60kg on top.
