ARB Differential Breather Kit, High-Flow, 4-Port Manifold

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

Had these professionally installed on 2010 Lexus GX460 for the front and rear differential. Really love the quality, durability and ease of installing under the hood. Went through mud and water a couple of times with no issues. The price was a little more then it should have been for some plastic tubing and breather. Curious to know if the transfer case and transmission have a breather also that I could tie into this set.

ARB- the king of offroading.

Did the update on 4runner rear differential. Did not use the self threaded bolts that come in the kit. Bought an M6 bolt and bolted the manifold to an existing threaded hole in the passenger side of the engjne bay, next to the air filter. Comes with 4 plugs for two breathers but can buy extra plugs since manifold holds up to 4. Video overview on how to below. https://youtu.be/Ob6oHB7vaGE?si=2yMG20bfem79G_0o

Easy install on a 5th generation 4runner. There is a 6mm threaded pitch hole on the passenger side of the engine compartment that works well for the bottom bolt of the manifold, then just use one of the self-tappers included to lock it into place. I went ahead and grabbed some t-barbs and waterproof tape to add a junction to the breather just above the rear differential so I could also extend the breather for the rear locker. https://amzn.to/408wvRq and https://amzn.to/3SXF25P Took me about 30 minutes total, easy mod that will set your mind at ease so you don't go polluting your gear oil or blow out your seals.

After taking our 2021 4Runner out on a couple off-roading adventures, we realized that we needed to mod our truck to prevent any possible issues with water getting in our rear differential. This kit did the job! First with the positives. This kit has everything you need for modding your truck. I mounted the manifold in the engine and still had plenty of tubing left over. I'm also very happy with the quality of the manifold and tubing (though with a complaint, see below). The push-connect parts also made installation very easy while giving confidence that it won't pull out. I only have two complaints with this kit. First, some steps in the instructions weren't the easiest to understand, but there are plenty of YouTube videos to get around this. More concerning is that the sturdiness of the material causes the tubing to kink very easily due to the natural coil. If you don't straighten out the tubing before running it through your truck, DO NOT pull to uncoil the tubing. Take the extra time to carefully uncoil the tubing. I mistakenly pulled on the tubing too hard to straighten it out and it bent right in half. I was worried this kink would cause the tube to crack, but fortunately it did not. This is an awesome kit and I recommend this if you plan to do any water fording in your truck. It's an easy DIY, even if you're like me and do not have much experience working on cars.

Of course it will fit any other truck depending on model but this kit was enough to do both lines on my ‘18 4runner; rear differential and elocker. Came with 32’ of tubing (cut in half, 16’ for rear diff and one for elocker) Had about 2’ of tubing left. Ran the tubing each from diff and elocker to engine bay by steering pump. Only hard part was routing the tubing above gas tank and securing it via zip ties. Ran along drive side frame rail and above gas tank to the rear diff ... ran the second line following the first tubing to the elocker. Of course I could’ve saved and sourced all the tubing and parts from auto store but I like supporting arb and they have been around before I was born!

Buena calidad, su instalación fue sencilla

Works well

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