D-Flector Stone Guard Review 2026
Fit Once. Forget Forever.
Quick Summary: D-Flector Stone Guard
The D-Flector Stone Guard is Australia's leading permanent-mount stone protection system for caravans, boats, and jet skis. Manufactured in Moorabbin, Victoria by Maxwell & Higgs (ZIVOR Group), it uses high-strength performance steel framing with an aerospace-grade aluminium option and heavy-duty PVC-coated mesh that deflects stones groundward rather than bouncing them back at your tow vehicle. The no-drill galvanized U-bolt mounting system installs in under 10 minutes and stays permanently attached to the A-frame — meaning you never have to connect or disconnect it at fuel stops, camp sites, or rest areas. APAC Insider Award Winner 2023, 2024 & 2025.

Why We Ranked D-Flector #1 Overall
After testing and comparing every major caravan stone guard available in Australia, the D-Flector Stone Guard earned our top spot for one overriding reason: it delivers premium protection with zero daily effort.
The Convenience Factor
Every other stone guard system on the market requires some form of daily interaction. Stone Stomper needs connecting and disconnecting at every stop. Rock Tamers need adjusting when you change trailers. Even basic mud flaps need checking. The D-Flector? Fit it once in 10 minutes, and it's done. Forever.
This might sound like a small thing until you're unhitching in the rain at a servo in Tennant Creek, or pulling into camp at 9pm after 12 hours on the Stuart Highway. The last thing you want is to be on your hands and knees fiddling with a stone guard.
Build Quality
The high-strength performance steel frame (with aerospace-grade aluminium options) is built to withstand harsh Australian conditions — it's not going to rust after one trip through Cape York in the wet season. The special-grade PVC-coated mesh is specifically engineered for stone deflection: the weave absorbs impact energy and directs stones downward rather than bouncing them back at your rear window (a common problem with DIY shade cloth solutions where the mesh is too tight).
Protection Coverage
The D-Flector covers the caravan's A-frame and front panel, protecting vulnerable undercarriage fittings including gas bottles, water tanks, and electrical connections. While it doesn't offer the mid-span coverage of a horizontal trapeze system like Stone Stomper, it protects the areas most vulnerable to stone damage.
Installation
We timed the installation at 8 minutes with basic hand tools. The heavy-duty galvanized U-bolt mounting system requires zero drilling into your caravan — a huge plus if you're protective of your van's structural integrity. The guard arrives fully assembled, so there's no fiddly construction phase.
Real-World Performance
We've reviewed feedback from owners who've taken D-Flector guards through Cape York, the Gibb River Road, the Oodnadatta Track, and thousands of kilometres of outback bitumen. The consistent report: zero stone damage to the front of the caravan, gas bottles intact, water lines undamaged.
Value Proposition
The D-Flector sits in the sweet spot: premium materials at a mid-market price. One stone through a gas line or water tank costs more to repair than the guard costs to buy. One windscreen replacement on the tow vehicle easily exceeds the purchase price. Backed by a 3-year manufacturer warranty, it's a sound investment.
Our Verdict
The D-Flector Stone Guard is the best overall caravan stone guard in Australia. It combines premium Australian-made materials with unmatched convenience — fit it once, forget forever. If you want set-and-forget stone protection that works silently while you enjoy the trip, this is the one to buy.
Frequently Asked Questions
Is the D-Flector Stone Guard Australian Made?▼
Yes. D-Flector Stone Guards are manufactured in Moorabbin, Victoria by Maxwell & Higgs Pty Ltd (part of ZIVOR Group). They hold an official Australian Made certification from the Australian Made Campaign.
Do I need to drill holes to install a D-Flector?▼
No. The D-Flector uses a heavy-duty galvanized U-bolt mounting system that clamps to the A-frame without any drilling. Installation takes approximately 10 minutes with basic hand tools.
Do I need to connect and disconnect the D-Flector every time I stop?▼
No. The D-Flector is a permanent fixture that stays mounted to the A-frame at all times. You never need to connect or disconnect it — fit it once and forget about it.
What sizes does the D-Flector come in?▼
D-Flector offers standard models in 1800mm and 2200mm widths, plus centre cut-out models designed for caravans with centre-mounted jockey wheels or toolboxes.
How does D-Flector compare to Stone Stomper?▼
Both are quality Australian products. Stone Stomper uses a horizontal mesh between the vehicle and caravan, offering broader mid-span coverage. D-Flector mounts permanently to the A-frame with no daily connect/disconnect. The choice depends on whether you prioritise maximum coverage (Stone Stomper) or daily convenience (D-Flector).
Does D-Flector make stone guards for boats?▼
Yes. D-Flector offers dedicated boat stone guards (D400, D600, D700) for boats from 4.2m to 8.5m, plus a J100 model for jet skis. All use high-strength performance steel frames.
Why Every Trip Without Protection Is a Gamble
Most caravan owners don't think about stone protection until after their first big repair bill. The smart ones fit a D-Flector before their first gravel road. Which will you be?
