Customer photo review of 4x4 Magnetic Chassis Flusher Kit

This thing is amazing!!!! I used this after I cleaned underneath the4B and this was the amount of sand that came out!!! Once again. I used this AFTER I had already cleaned the chassis.

4x4 Magnetic Chassis Flusher Kit

Perfect fit, tough, and no kinks! Solid brass fittings, bright fluorescent green so you can't lose it, and flexible enough to get where you need it. Built to last — no twisting, no collapsing under pressure. Exactly what you need. 5 stars!

Previously flushed out and thought the chassis was clean. When I used the flusher it was amazing how much more mud was removed. Great product.

4x4 Magnetic Chassis Flusher Kit

Works very well , doesnt fit into the smaller holes on chassis though , so I still manually flush the front part of my car

Customer photo review of 4x4 Magnetic Chassis Flusher Kit

Decided to try Rust shield on my new supwr duty xlt rather than getting it pro rust proofed. Rust shield was easy to apply but recomend PPE on eyes and face, take your time and dont apply to thick. Once it cures it has a satin finish. Impressed, will reapply every 6 months.

Flusher Hose

Good strong magnets hold it firm against chassis rails. Good power in the jets does a good job cleaning years of buildup out of the frame.
