Brass Outer Portal Drive Housing Knuckle Cover Upgrades Part for TRX-4/TRX-6 Crawler RC Car, 8PCS Outer Portal Drive Housing Knuckle Cover,Black

I ordered the Quality Solid Brass ARRCat TRX-4 Knuckle Cover Upgrades parts for my TRX-4, it was time for a rebuild and wanted to add some additional weight on the bottom to make her much more stable, so far the Brass ARRCat parts are designed and machined to very tight tolerances, the powder coat finish is extremely durable making them the clear choice for my TRX project. I am still in the process of the build, I want to do it right this time so more ARRCat parts are on the way to round my set out. I cannot say enough about the quality of these ARRcat parts, they are uniform in design matching the original parts perfectly. They are made of Brass that add real value to my truck in many ways, no doubt these parts will last a lifetime and then some! DYNOMITE - FIVE STAR - ARRCAT BRASS TRX UPGRADE PARTS - A REAL WINNER IN MY BOOK!!

I received this ARRCat Upgrade Part Kit for my TRX-4. They are very similar to other items I have purchased for my TRX-4M, and are quality cast brass parts. Everything fits great to plastic, but is a struggle to fit with other brass parts. Just be forewarned the tolerances are great for plastic, but not for metal. Make sure to use threadlock as these can come loose fairly easily with heavy use.Overall I would purchase again for my RC's.

The media could not be loaded.  These have a nice quality finish fit and feel and there is quite a bit of weight to them I noticed a difference crawling over some tree stumps and bricks in my front yard instantly once installed however in the video I uploaded you can see a flaw that I discovered on installation there is at least double the amount of free play in the wheel axle which maybe easily solved with a flat washer of some type underneath the axle itself because the new part has slightly different depth for the bearing install then the factory parts I show these details in a picture of the two housing side by side that the that the new upgraded part is slightly deeper hard to see but anyway I put the picture. The video does point out quite well where you can see that the factory has very little free play but the upgraded part has at least a millimeter or so freeplay I ran the truck like this though figuring that the mesh of the gears could not be lost with such a small amount and it just would be a nuisance at minimum if there is any adverse affects to this I will upgrade this telling you what happened to me after crawling quite a bit of course this is the type vehicle that you don't tend to do much very high speed stuff with mostly just low speed crawling over stuff and getting a kick out of it so this might not ever be an issue.

These diff covers are very weighty at 138g for the pair. Super easy install and it adds welcome unsprung weight to your TRX4 or TRX6. The black brass keeps things stealthy, with just a hint of bling tastefully shining through. I reused the stock hardware and kept the included ones as spares. Be sure to use blue thread locker on the hardware.

If you want LCG for your rig, this is it, and it's unsprung weight! Well made, good powder coating, and comes with screws needed. Very good upgrade to keep that belly low
