After I ordered these housings for my Traxxas TRX-4 Sport High Trail, I saw a YouTube video with someone with the same kind of housing trying to get his to fit together. But I noticed that he was doing both the inner and outer housings with brass and that he had to use a dremel to shave a little off the inside to make them fit. I was concerned if I was going to have the same issue, but thankfully, they fit like a glove to the stock inner portal housing. They look great and there are no issues with them fitting behind the original stock wheels. Definitely gives the front of the truck some extra heft. I got the 7.38oz version.

When upgrading to brass, this is the place to start in the rear, great fit and easy to install

COOWOO has 2 different versions of outer brass portal housings. One around 3oz and the other around 6oz. These are the 6oz ones and I used them on the front axle. I used the 3oz ones on the front. Fit is snug and nice.If your TRX4 is built like a scale truck with a heavy body, then these weights definitely help to keep the portal axled TRX4 planted. Great way to keep the center of gravity low.

These brass outer portal housings were a perfect fit on my TRX-4 and the added weight definitely helps to lower the vehicle center of gravity to provide increased traction and reduce unwanted wheelies when climbing steep grades. Improves overall vehicle stability. Good product.

These fit the factory housing very snug I had to tap them on. The inner portals also had to have some massaging to get them into position. Pet peeve of mine is the bolts go in from opposite sides now where they attach to the housing opposed to both starting from the same side like stock

I received these COOWOO Brass Outer Portal Drive Housings to review today. These are the 3.15 oz version for Front and Rear.Installation was quick and easy once you get your vehicle taken apart. I've been able to get ahold of quite a few COOWOO parts over the last several months and they have generally gone on well but the fitment is snug. Do not force them with your plastic parts as being metal they make breaking the plastic parts so much easier....You will want to use threadlock when installing these. While not as heavy as the 6.38oz version these still add quite a bit of heft and helped "keep the wheels down" while using the vehicle on the mud track. I did pick up both sizes as I like to have the options of the heavier set on rocks and the lighter set on mud tracks but to each their own.I would purchase these again!
