COOWOOBrass Caster Blocks C-Hubs Upgrade Parts for TRX-4M 1/18 RC Crawler Car Total 0.32 Ounce Front Counterweight, 2PCS Black

Killer fit and finish

Direct replacement. Very nice brass bar. Came with the ball joints and grommets to install. It took maybe 10 min to switch out. The added low weight seems to help. For the price it's kind of a no brainer. I would recommend and would buy again.

Decent upgrade kit. Can't use it on my rig (not a TRX-4) but looks and feels great in the hands.

This is a really nice diff covers, it fit perfectly in my TRX4M and improves the performance of the truck in since they lower the CG, the machining is great and the look is also really nice, I am giving 4 stars because the included screws are 1mm hex screws and the platform originally comes with 1.5mm hex screws this will make you to have 2 different screw drivers to give maintenance to the truck

Nice parts that went on pretty smoothly. really happy with them for the price.

The parts upgrade package from COOWOO is enough to get your 1/18 crawler to stay grounded better than stock. Replacing the stock parts for these brass one will make a great difference in performance of your mini crawler. The parts almost look gold when they are installed. I'm very happy with the set, it was easy to install and everything fit right. Be careful with the stock diff cover screws they strip out easy and be sure to replace them with the included ones.

I was unaware that coowoo was RCEvolution under another name. Great way to get the same quality stuff at a fraction of the price.Everything came packages separately, and group packages with the applicable screws so nothing gets mixed up. These lowCG brass bolt ons will work perfectly to keep the wheels down on my TRX-4M project.

Front steering link too short so alignment is off and there's no way to fix. Very disappointed. Spend your money on better parts. I wish I could return this item
