The Groundswell Offroad Underbody Protection Kit is built to defend where it matters most: your 4WD’s undercarriage. Designed for serious offroaders, it delivers both deep cleaning power and long-lasting protection to keep your chassis clean, corrosion-free and ready for the next adventure across beach tracks, muddy trails or outback terrain.
Introducing the all-new Underbody Jet Pro
At the heart of the kit is our new Underbody Jet Pro, 12 months in the designing and machining. It’s CNC machined on the Sunshine Coast from 25mm x 25mm solid aluminium square bar and rolls on Australian-made wheels. Twin jets sit on the bar, fed by our own Y-pipe design at the rear, so you get even, powerful water flow straight up into the chassis rails, wheel arches and every hidden corner where salt, sand and mud like to hide.

I picked up Groundswell’s Triple Protection Bundle and I’m seriously impressed. I’ve used the Offroad Wash and Underbody Spray before and absolutely love them — after my last trip to Teewah Beach there was barely any sand left on the car!
I’m heading to Fraser next, and after trying out the new Offroad Protective Sealer, I feel like my car is properly sorted and ready to go.
Honestly, couldn’t recommend these products enough. Groundswell, you guys are killing it!
I don't generally leave reviews for a lot of products, however this red dirt wash has genuinely worked wonders for me, I had a mixture of red dirt dust and mud that had stuck to everything after a big trip and was struggling to remove the excess on my sills and underbody.
I just added the recommended amount into a pressurized spray bottle and let it sit on the affected areas for a few minutes and it took off a massive amount with no agitation. I've used multiple other snow foams etc prior with no luck.
It didn't remove everything entirely however next time I go to clean it I will agitate the rest and no doubt it will all be gone. This mud has now ingrained itself after a 8/9 months and wasn't fresh.
Overall im extremely impressed.
Thanks guys.
Excellent service provide by these guys. Snow Foam Cannon arrived just before Xmas but was damaged during transit to WA. Emailed them and a replacement was sent within a week during the busy Xmas/New Year period. New gun works brilliantly.
