Salt Shift Magnetic Chassis Flusher with Hose — 6‑Jet Underbody Nozzle with Magnetic Mount

The Salt Shift Magnetic Chassis Flusher is a hose-powered undercarriage nozzle that magnets to your frame and sprays high-pressure jets to remove mud, salt and grime from vehicle chassis.

Salt, road grime and wet mud collect on frame rails and suspension parts where a regular wash won’t reach. The Salt Shift Magnetic Chassis Flusher combines a multi-jet nozzle, a magnetic mount and an included extension hose with a US garden-hose adapter so you can quickly rinse the undercarriage at home or on the trail. Built from ceramic-reinforced nylon and brass fittings, it’s made to resist corrosion and deliver consistent flushing power to help slow rust and keep moving parts cleaner.

How does the magnetic mount stay secure while flushing under the vehicle?

The chassis flusher uses six rare-earth magnets positioned to grip steel chassis rails and hold the nozzle steady while water sprays. That hands-free hold prevents the unit from shifting when jets are firing, so you get even coverage without balancing the tool under the car. The compact shape and balanced jet pattern reduce drag and make it easy to attach and remove.

• Six rare-earth magnets for a firm, stable attachment to steel frame rails.
• Compact, balanced nozzle design minimizes movement during high-pressure flow.
• Easy on/off placement—no tools required to mount or remove.
• Works with common chassis shapes for a broad range of vehicles.

What cleaning performance can I expect from the six high-pressure jets?

Each of the six jets is angled to blast accumulated salt, sand and caked mud out of nooks and hard-to-reach cavities. The jets produce a concentrated, forceful stream that dislodges debris without needing a pressure washer—using only a standard garden hose and the included adapter. Regular use helps slow corrosive damage by removing lingering contaminants that trap moisture against metal.

• Six targeted jets for thorough underbody coverage and debris removal.
• Effective with municipal water pressure—no specialized pump required.
• Designed to reach frame rails, crossmembers, and suspension components.
• Works with detergents or Salt Shift concentrates for deeper cleaning when needed.

How do I set it up and what accessories are included?

Setup is a simple DIY process: attach the supplied extension hose to the flusher, screw on the US garden-hose adapter and connect to an outdoor spigot. Place the magnetic flusher on the chassis rail beneath the vehicle, turn on the water, and let the jets do the work. If you want extra cleaning power, add a compatible chassis wash or Salt Shift concentrate to help loosen stubborn grime.

• Included extension hose and US garden-hose adapter for immediate use.
• No special tools or pumps—connect to standard garden spigot.
• Compatible with Salt Shift undercarriage formulas and other rinsing agents.
• Quick attachment, hands-free operation, and easy removal for storage.

Will this fit my vehicle and protect against corrosion?

The flusher is designed for vehicles with exposed steel chassis rails—cars, trucks, SUVs, 4x4s, trailers, RVs and boat trailers. While regular flushing cannot reverse existing corrosion, removing salt and trapped debris reduces the environmental triggers that accelerate rust. Its non-corrosive brass fittings and ceramic-reinforced nylon body mean the tool itself endures road conditions and repeated use.

• Fits most accessible chassis rails on trucks, SUVs, trailers and RVs.
• Materials resist rust and wear for long-term reliability.
• Regular use helps limit salt-induced corrosion and parts deterioration.
• Great for post-winter, post-coastal, and post-off-road maintenance routines.

Who this is for: The Salt Shift Magnetic Chassis Flusher suits home mechanics, off-road enthusiasts and anyone who wants an easy, affordable way to rinse the undercarriage without a pressure washer. If you own a truck, 4x4, trailer or seasonal vehicle exposed to salt, sand or mud, this tool makes underbody cleaning quicker and more effective, helping you protect structural components and reduce long-term maintenance costs.
