Salt Road 4x4 Undercarriage Protection Kit

Winter salt is brutal on 4WDs. Salt and brine pack into suspension arms, skid plates, crossmembers and boxed chassis rails. The Salt Road 4x4 Undercarriage Protection Kit is engineered to deep-clean your underbody and add a hardened protective coating that lasts the entire season.

Salt Road Wash dissolves hardened salt, breaks down brine film and neutralises corrosive chloride ions while leaving behind corrosion inhibitors to slow rust formation. The Single-Jet Underbody Blaster, powered by your pressure washer, clears mud and salt from the underside of your rig fast. Pair it with the Flusher Canister and Chassis Flusher to push foam through frame rails and hidden cavities where corrosion starts first.

Once fully cleaned, finish the job with Rust Shield, a curing, non-stick underbody coating that hardens in 3–4 days and protects for 6–12 months. The hard and soft bristle brushes help with stubborn areas, while All Purpose Cleaner prepares surfaces when needed.

Use this kit before winter or ahead of mountain trips, then maintain with Salt Road Wash throughout the season. Clean first. Protect properly. Drive confident.
