Choosing The Right Product: Important Considerations

Follow our five-step process to order your ideal ROCK OFF Towing Brush Strip Kit.

Step 1: Where its going…

Before ordering your ROCK OFF® Stone Guard, it is important to consider where and how you are going to mount your Brush.

Vehicles come in all shapes and sizes, which is why ROCK OFF comes in a range of ready-to-install Mounting Kits for convenient fitting on your towing vehicle, caravan or trailer. Time to get under your 4WD or caravan to get a closer look!

Remember, there is no “one size fits all” as every vehicle set up is individual.  Our range is designed to cover most vehicles, but you may need to consider discussing your set up with your local vehicle modification specialist, or caravan service centre.

ilsutartion-1

Step 2: Weight considerations

You will need to allow for weight limits for your towing vehicle, adding a ROCK OFF Caravan Stone Guard Brush will add additional weight to your set up. However, you will find that your ROCK OFF weights are lighter than other products, and also provides better air-flow under your vehicle.

Additional weight:

For our Stainless Steel Rails add another 2.5kgs, and a set of Stainless Steel brackets allow another 1.5kg to your set up. (weights are approx.)

Disclaimer: It is your responsibility to ensure this product is suitable for fitment and use with your intended towbar and vehicle.

Step 3: Measure your mounting height

Take your height measurements at a time when your towing vehicle and caravan or trailer is fully loaded — this will ensure any suspension systems you have in place are considered.

Measure from the ground to the mark where the top of your ROCK OFF Mount will be located. Deduct 100mm for road clearance and a further 50mm allowance for the backing of the brush and Mounting rail, total 150mm. This will provide the ideal bristle length option for your vehicle.

Remember that our drop down options shows the “bristle length”, so you will need to allow 50mm for the brush backing when you choose. If unsure, choose your ROCK OFF at the shorter measurement – you can always lower your fitting later.  If your ROCK OFF bristle is too long, it is difficult to trim

Please Note: Insufficient clearance may cause dragging on rough or rutted road surfaces and reduce ROCK OFF’s lifespan. Excessive clearance may reduce ROCK OFF’s effectiveness.

Step 4: Exhaust considerations

Keep exhaust flow and heat away from ROCK OFF. This product performs best when installed with plenty of distance away from your vehicle’s exhaust outlet. ROCK OFF is made from tough Polypropylene fibre, but it can be damaged by exhaust heat build-up.

Exhaust Shield and Extension Kits are available to allow free flow of your exhaust heat away from your towing vehicle. Alternatively, consider modifying your vehicle’s exhaust system to a side-exit style.

Recommended mounting positions:
  • For towing vehicles with a straight exhaust outlet: Consider mounting ROCK OFF underneath the exhaust pipe.
  • For towing vehicles with a downward-facing exhaust outlet:
Consider our Exhaust Extension Kit. Particularly if your exhaust outlet is less than 450mm from your intended ROCK OFF Mounting.

Step 5: Other considerations

Aftermarket accessories (mudflaps, chains, Anderson plugs, auxiliary fittings etc) may need consideration when determining the mounting height and bristle length of your ROCK OFF.

Rigid-style mud flaps are recommended if using in conjunction with ROCK OFF. Flexible and/or chain-attached mud flaps are not recommended as these can cause stones to bounce underneath ROCK OFF and strike your vehicle.

Check access to accessories and auxiliary fittings such as Anderson plugs and reversing lights. These accessories may have components or cables which may impact your mounting position. If possible, mount ROCK OFF underneath or above these fittings to ensure easy access.

Why Choose ROCK OFF®

Protect your investments

We know how much off-roading fans and outback explorers adore their caravans, campervans, and boats. Why not add some protection to your investments and greatly reduce the risk of stone damage?

The quiet brush stone guard solution

Our innovative bristled design is made to be super effective at guarding against stones without creating a loud racket. So it won’t drown out your favourite road trip tunes with annoying thudding from stone impacts.

Doesn’t get in your way

Unlike some stone guard systems, ROCK OFF doesn’t occupy a lot of space in your towing setup. When it’s installed you can still move freely around and between your vehicles and enjoy normal access to your boot. No more fiddling around removing stone guard hardware after a long drive on the dirt.

What our customers say...

I’ve purchased Rock Off to help protect the underside of my caravan from stone damage as I expect to undertake some pretty serious outback journeys in the near future. Whilst I have Stone Stomper to protect the front of my caravan, that product doesn’t necessarily reduce stones from damaging under my van and this is where Rock Off will assist. Customer service with the Busy Bee Brushware team was excellent and the product was very easy to install under my caravan using a length of angled aluminium from Bunnings.

The process was quick and easy, delivered to my door in WA within 7 days and very easy to install. Will see how they go on the road test next week.

Great product. I installed Brush on back of my Isuzu mux to protect caravan from stone chips. Have just done the lap of WA including going across the Gibb River Rd. and that road had way too many stones and rocks flying up. But brush did the job it was designed to do and very well.

Increased Protection

Our Rails and Brackets are made from heavy duty Stainless Steel to handle the rigours of the dirt highways. Prevent nasty dings and scratches to the front of your caravan and reduce the chance of stone bounce back taking out the back window of your vehicle. ROCK OFF also protects the underside of your caravan, including pipe-work, tanks, electrical, and your valuable suspension.

Less Drag & Impact

ROCK OFF’s brushes are lighter than mud flaps, allowing greater airflow and creating less drag. Mudflaps tend to bounce stones off in unpredictable directions, whereas ROCK OFF’s bristles absorb the impact of the rocks, taking the force out of them.

Easy Maintenance

Once installed, ROCK OFF® stays out of your way so you can access all areas of your vehicle as normal, including the boot.
