About this product

The Chassis Grenade is a magnetic chassis flush device designed to blast out salt, sand, and mud deep inside your vehicle’s chassis rails and hard-to-reach areas. Attach it to your offroad rig, truck, or trailer frame, connect it to The Captain’s Musket, and let the high-pressure water jets do the work.

✅ 360° spinning nozzle for full coverage and deep cleaning
✅ Powerful magnetic base secures it to chassis rails for hands-free operation
✅ Flushes out built-up salt, sand, and debris, preventing rust and corrosion
✅ Easy quick-connect setup with The Captain’s Musket or standard hose adapters

Protect your undercarriage from rust and clean your chassis with the Chassis Grenade—because what you can’t see can still cause damage!

FAQ

1. What is the Chassis Grenade?

The Chassis Grenade is a magnetic chassis flusher designed to remove built-up salt, sand, and debris from inside your chassis rails. It uses a 360° spinning nozzle to spray water in all directions, providing a deep, hands-free clean.

2. How does it work?

Simply attach the Chassis Grenade to your chassis rail using its strong magnetic base, connect it to The Captain’s Musket or a compatible hose, and turn on the water. The high-pressure spinning jets will flush out contaminants, helping to prevent rust and corrosion.

3. Is it safe for all vehicles?

Yes! The Chassis Grenade is perfect for 4WDs, trucks, trailers, caravans, and any vehicle with a hollow chassis. It’s designed to fit into standard chassis rails and can be moved to multiple locations for a thorough clean.

4. Can I use it without The Captain’s Musket?

Yes! While it works best with The Captain’s Musket Foam & Flush Gun, you can also connect it to a standard garden hose using the correct quick-connect fittings.

5. How strong is the magnet?

The heavy-duty magnet is strong enough to hold the Chassis Grenade in place during flushing but can still be easily repositioned as needed. It ensures a secure, hands-free clean.

6. How often should I use it?

If you take your 4WD off-road, drive on the beach, or live in a coastal area, using the Chassis Grenade after every trip is recommended to flush out corrosive salt and debris.

7. Can it be used with rust inhibitors or cleaning solutions?

Yes! You can run Chassis Flush Solution or other anti-rust treatments through it for added protection.

8. How do I store and maintain it?

After each use, rinse it with fresh water, check for blockages, and store it in the included mesh storage bag to protect it and keep all fittings secure.

9. Why do I need a chassis flusher?

Salt, mud, and sand build up inside chassis rails, leading to rust and long-term damage. A quick hose down isn’t enough—the Chassis Grenade provides a deep, targeted flush, extending the life of your vehicle’s undercarriage.
