Underbody Jet Pro

Underbody Jet Pro
CNC machined on the Sunshine Coast. Australian made.

Take your underbody cleaning to the next level with the Underbody Jet Pro, built for serious 4WDers who tackle Australia’s toughest terrain. Its 12 Jet interchangeable design delivers concentrated cleaning power that blasts away caked-on mud, red dirt, clay, salt and sand faster and more effectively than standard underbody systems. It gets into the chassis rails, diffs and suspension, where corrosion starts.

12 months in the making
We got sick of cheap, flimsy underbody cleaners that fall apart. So we spent 12 months designing our own. It’s CNC machined by our machinist here on the Sunshine Coast, then assembled by hand in our workshop. We even pulled two of our best-selling kits, the Ultimate Kit and the Underbody Kit, until it was ready.

The log bridge on the Old Telegraph Track (OTT) in Cape York is an iconic, precarious, and often nerve-wracking river crossing located at Cypress Creek. It consists of narrow logs, often reinforced with ratchet straps, spanning a significant drop. It is known for being shaky and requiring careful spotting to navigate safely.

Customer photo review of Triple Protection Bundle 5lt

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!

Triple Protection Bundle 5lt

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.

Mud Red Dirt Wash - Outback & Bush Wash

Always good to deal with this company great value, fast shipping and good back up service.

The Jett Chassis Flusher Kit

great product I will be back for more

Offroad Kits

Really happy works perfectly. I tried other brands they couldnt compete with the groundswell product results.

Premium Wash - Beach & Salt Wash

I liked this product got rid of clay that had been on the ute for few weeks seemed to dissolved it with some hard scrubing

Mud Red Dirt Wash - Outback & Bush Wash

A much better way to spray the underside of your vehicle than the trigger operated sprayers. Also great that it’s solvent resistant.

Solvent Pump Sprayer 1lt

The pump up pressure sprayer is much easier to apply an even coating than the trigger type sprayer.

Underbody Protection Pro Kits

The Jett Chassis Flusher

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.

Snow Foam Cannon

Works well but I wouldn't say it works any better than some of my other products that weren't designed to get rid of red dirt.

Mud Red Dirt Wash

Get product, amazing service, very effective coating. Keep up the great work.

Underbody Protection Spray

Every part as good as Bowdens Happy Ending and much cheaper

Hydro Protection Foam

Haven't used it yet. Quick delivery and good value if works as claimed.

Snow Foam Cannon

Works really well came back from Moreton Island and it flushed out that much sand I was amazed

The Jett Chassis Flusher

Works too well. The amount of sand that came out of the chassis was amazing. Cant wait to go beach driving again just to use it.
