- BBenVerified ReviewerI recommend this productRated 5 out of 5 stars1 month agoEssential kit for your offroad rig
We got this unit to go with our 4wd Essentials bucket. The chassis grenade makes it easy to get flush and water into the chassis holes and rinse out the alarming amount of dirt, sand and salt from inside it. Easy to use and connects to the musket so you can put chassis flush or wash through the grenade. An Important but less thought of way to look after your rig. Recommend.
