Highly recommended
A must-have upgrade for serious off-roaders and overlanders. Reliable, well-built, and worth it for the protection it provides.

ARB make some good stuff and this is no different. The 2 sheet metal screws are short so I chucked them and use stainless nylock and bolt. Much more secure. I put mine behind my passenger taillight as high as I could. Getting a drill in wasn’t easy but it worked. I took my time running the hoses to make sure they are hidden and away from damage. Happy the way it turned out but seeing how it actually works in mud and water will determine my over all satisfaction.

Worked great! I connected the front and rear breathers together at the manifold. I positioned the breather in the engine bay. Great product
