TRX-4 1:10 x4PCS Heavy Metal Brass Internal Wheel Knuckle Weight Fit for TRX-4 (A Style)

Fit perfectly on a TRX4 High Tail. No modifications to the truck, rims, or portal covers needed.

Fits perfect and adds good amount of weight

Half the cost of other brands, same exact thing. These are all made in the same factories in china, don't pay more for a chunk of brass and a brand name. you cant see the logos when its installed lol. the machining was perfect on all 8 of the ones i got.for the poster who said it will rub the webbing on a stock wheel. it doesn't. if you put the hex nut in the wheel off the vehicle and then put the weight in the wheel it seems like it rubs. however.. when the nut is actually on the axle it is spaced further and does not actually touch the wheel weight. the gap inside is fine, it doesn't rub when assembled. this is my experience with 8 of these spacers on two different trucks, all stock wheels.it doesnt come with screws. use the one with the truck. use thread locked on the back 6 screws going into the weight. do not over tighten the bolts. its easy to install, i didnt take the portal assemblies off. just took the wheel off, popped the 8 screws. took off the plastic cover, knock it on the table to knock out the bearings. put the bearings in the weight, put the screws back in. i had the truck on its side so i didnt need to take the axles out, just took the covers off. easy. if your truck is worn its a good time to put a touch of grease in there. if its new i wouldnt worry about it, the portals are already greased (or should be). all mine were fine. dont cake it with grease, it just needs to be a wet film really.these were the same product at 50% of the cost. if you are doing multiple vehicles its a no brainer, dont waste money on another brand for a chunk of metal.

I did not have any problems fitting bearings on a TRX-4 Sport. Hubs were well machined and fit perfectly. The stock wheels did not fit, and the Injora beadlock wheels I had purchased to use just barely did not fit either. The 2mm screws on the inside of the beadlock touched just a little. I ended up adding Treal 5mm hexes and extended axle pins, and the end result is great. A little extra cost but wow these add some serious weight. Only got a little runtime on them more, but noticeable less roll overs.

Build Quality seems pretty good. I was surprised by the actual weight of them. Installation is easy, just note they dont come with bearings so you need to transfer them over.

Low weights prevent roll overs and really helps. THIS product is great. But man. Traxxas no matter what I am working on- they always freaking SPOT WELD at least one bolt. In this case ONE axle pin was unable to be removed. Despite drilling, tapping, blow torch. Evidently… that’s how they sell new axles and drive gears. So. Add 30$ to my project ….. great product but be aware. Working on anything TRAXXAS never goes as planned.

Adds a lot of weight at the lowest point of the vehicle, noticed improvement immediately! I put them on all 4 portals, the truck stays grounded now. Looks great too!

Super heavy, high quality, and perfect fit. Keeps the truck much more planted now. Used to constantly roll over. Looks nice, and very happy with them.
