Amazing result. Really easy to thread through chassis. Flushed out an astonishing amount of mud and grit
The Groundswell Jett Chassis Flusher Kit delivers deep, precision cleaning for the areas that matter most—inside your 4WD’s chassis rails. Designed to remove trapped sand, salt and mud, it prevents corrosion, extends your vehicle’s life and keeps your underbody in top condition after every offroad adventure.
The Jett Chassis Flusher Kit is backordered and will ship as soon as it is back in stock.
Engineered for serious offroaders, the Jett Chassis Flusher Kit features a powerful 12-jet design that flushes the full length of your chassis rails. The built-in soap canister and ball tap give you complete control, combining high water pressure with cleaning agents for a thorough internal wash. Built tough from stainless steel, it’s made to perform in Australia’s harshest environments.

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!

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

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

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.
