4 Piece 7mm Brass Extended Hex Wheel Hubs Compatible with SC x 24 Wheel Spacers RC Brass Weight Hex Hub Extended Combiner with a Cross Wrench Compatible with SC x 24 1/24 RC Crawler Car

I used this on a RocHobby 1:18th Fire Horse and while the provided axel nuts did not fit stock i followed the advice of someone else in reviews who stated they drilled them out with a 1/16th drill bit and then proceeded to tap them with a M2.5 tap. However, upon going to drill them out i found it was unnecessary, for me at least, because the drill did not even touch the threads as it was too small so i simply tapped them with an M2.5 tap and a pair of pliers and they work perfectly. The spacers themselves fit perfectly and as you can see in the pictures really gave this car a nice wheel width and look. The provided axel pins did not fit but i did not need them as the ones my car used stock worked just fine. All in all 9.5/10 only because it'd be nice to able to request different size axel nuts.

Very worth it if you have lock tight. I’ve put these on 3 of my RCs and it gives stability and makes it look soo good!

Great for the price . Worked as they describe. Good amount of weight for you 1/24

These are made for the SCX24 or any crawler that has .2mm threads on spindle. But I used them for my Element Enduro 24 which has a 2.5mm thread. I bought a 2.5mm tap (Metric Machine Taps M2.5 x 0.45mm H2 ) I drilled them out with a 1/16 drill bit then tapped them.

Easy to install

These are actually machined and fit really good. They went on easy and gave the truck a great looking stance. Btw not the brass parts fault but if you are fitting bigger tires and then setting them wider with this kit an aftermarket steering servo is in your future the stock one is great and will last if you keep it stock but when you over stress it with bigger tires and lift it burns out or fry’s a gear with in days

I hesitate to call these issues, but certainly good for anyone to know. I can only comment on the C10 trucks.First, you will need to drill out the centers of your stock wheels with a 1/8" drill bit. This only removes a tiny bit of the plastic but otherwise, I wasn't able to insert the bolt.Second, after installation, I noticed that both stock wheels now rub on the body when turning sharply. I'll need to trim 1/4" of so behind each wheel.Otherwise, this was an easy to install upgrade and I weighed each hub + bolt at 2g, so a significant weight increase from the plastic stock hub and tiny metal bolt. The wheels are extended nicely.

So yes the title and description say 1/24 scale but the picture is clearly of 12mm hex nuts (note the size of wrench in comparison to hubs) and this was enough to throw me off and now I have baby extensions that won't ever fit my 1/10.... 4 stars because while I can't use the hubs at least now I get a wrench to use, it's got 4 hex nut sizes!
