The Parts You Can’t See Are Often the Most Expensive
When you’re driving through mud, water, sand, gravel or dusty tracks, your tyres don’t just throw debris behind the vehicle—they throw it directly into your engine bay.
Factory inner guards often leave large openings around the chassis, suspension and wheel wells. Over time, these gaps allow mud, stones and water to reach components that were never designed to be constantly blasted with debris.
The result
- Mud packed throughout the engine bay
- Water reaching electrical components
- Stones striking hoses and accessories
- Hours spent cleaning after every trip
If you spend thousands of dollars building your 4WD, protecting what’s under the bonnet should be just as important as protecting what’s underneath it.
Protect What Matters
Your engine bay is home to some of your vehicle’s most expensive components.
Depending on your vehicle, this can include:
- Alternators
- Wiring looms
- Belts and pulleys
- Air intake components
- Batteries
- Fuse boxes
- ECU wiring
- Washer bottles and reservoirs
Our HDPE Inner Guards are designed to provide additional coverage in areas where many factory guards leave gaps, helping reduce the amount of mud, water and road debris entering the engine bay.
Built for Australian Conditions
Whether you’re tackling Cape York, the High Country, Fraser Island, the beaches or your local weekend tracks, Australian conditions are tough on vehicles.
That’s why Trackco4x4 Inner Guards are manufactured from heavy-duty HDPE.
Unlike traditional rubber guards that can sag, split or deteriorate over time, HDPE is:
- Strong yet flexible
- Water resistant
- Resistant to cracking
- Easy to clean
- Designed to handle harsh off-road conditions

Less Cleaning - More Driving
Anyone who’s pressure washed mud from an engine bay knows how frustrating it can be.
While no inner guard can completely stop dirt entering the engine bay, additional coverage helps reduce the amount of debris that finds its way inside.
That means:
- Less cleaning after trips
- Less mud trapped around engine bay components
- A cleaner-looking vehicle between adventures
