Rock Off Brush Guard Review 2026
Bristle-Based Stone Protection
Quick Summary: Rock Off Brush Guard
The Rock Off Brush Guard takes a completely different approach to stone protection: instead of mesh, it uses 400mm-long industrial sweeper bristles mounted in an aluminium extrusion. The bristles absorb stone impact energy rather than deflecting it, meaning no stones bounce back towards the tow vehicle.

Pros & Cons
Pros
- +Australian made
- +Bristles absorb stone energy rather than deflecting — no bounce-back
- +No mesh to tear or degrade over time
- +Self-cleaning in rain
- +Permanent mount — no daily setup
- +Unique engineering approach that genuinely works differently
Cons
- -Bristles can trap debris and insects over time
- -Less proven long-term track record than mesh-based systems
- -Bristles may flatten under repeated heavy impacts
- -Limited availability — harder to source than mainstream guards
- -Narrower protection area than full mesh guards
Rock Off Brush Guard Review: A Different Approach
The Rock Off is the unconventional option in the stone guard world — and that's part of its appeal for owners who want something a bit different.
How It Works
Instead of mesh that deflects stones, Rock Off uses dense industrial bristles that absorb the kinetic energy of incoming stones. Stones hit the bristles and lose their energy without bouncing back. It's a genuinely clever approach that avoids the bounce-back issue entirely.
The Good
The energy absorption concept is sound and works well in practice. No stones bouncing back at your rear window is a real benefit. The bristles are self-cleaning in rain, there's no mesh to tear, and the aluminium extrusion is well-made. It's Australian manufactured with decent materials.
Considerations
Long-term durability under heavy bombardment is the main question mark. Bristles can gradually flatten under repeated heavy impacts, and they tend to trap small debris and insects between trips. The protection area is narrower than a full mesh guard, and sourcing replacements is harder than for mainstream products.
Who Should Consider It
If you like the idea of energy absorption over deflection and primarily drive on bitumen with occasional gravel, Rock Off is well worth considering. It's also a good option for owners concerned about stone bounce-back towards the tow vehicle.
Our Verdict
An innovative Australian-made alternative that works on a genuinely different principle. The bristle approach avoids the bounce-back problem entirely and requires zero daily interaction. Less proven long-term than established mesh systems, but a solid option for owners who value the energy-absorption approach.
How We Score
Scores are editorial opinions based on our published methodology. We weight stone deflection effectiveness (25%) and build quality (20%) highest. Durability (15%), installation ease (10%), daily convenience (10%), and value for money (10%) also contribute, with Australian Made (5%) and warranty (5%) rounding out the criteria. Different users may reasonably prioritise different criteria for their setup. See our full methodology for details.
Frequently Asked Questions
Do the bristles wear out?▼
Over time and under repeated heavy impacts, the bristles can gradually flatten. Longevity depends on how much gravel road driving you do. Highway-focused owners report good long-term performance.
