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.

Rock Off Brush Guard Review: A Different Approach
The Rock Off is the oddball of the stone guard world — and that's not necessarily a bad thing.
How It Works
Instead of mesh that deflects stones, Rock Off uses dense industrial bristles that absorb the kinetic energy of incoming stones. Think of it like a heavy-duty broom mounted to your A-frame. Stones hit the bristles and lose their energy without bouncing back.
The Good
The concept is sound: energy absorption vs deflection means no stones bouncing back at your rear window. The bristles are self-cleaning in rain, and there's no mesh to tear.
The Not-So-Good
Long-term durability is the question mark. Bristles can flatten under repeated heavy impacts, and they tend to trap small debris and insects. The protection area is narrower than a full mesh guard, and sourcing replacements can be tricky.
Who Should Consider It
If you're intrigued by the energy-absorption approach and primarily drive on bitumen with occasional gravel, Rock Off is worth a look. For serious outback touring, we'd still recommend a proven mesh-based system like the D-Flector.
Our Verdict
An innovative Australian-made alternative that works on a different principle. Interesting concept but less proven than established mesh-based systems. Best for casual tourers interested in the bristle approach.
Frequently Asked Questions
Do the bristles wear out?▼
Over time and under repeated heavy impacts, the bristles can flatten. Longevity depends on how much gravel road driving you do.
