DSPITWOD Technical Parts Beams Axles Connectors Bricks Sets - 420 Pieces, Frame Liftarms Beams for Technic Car STEM Building Block Toys

If you build legos often this is an excellent buy for the price. Often times you will come across a need to add in or replace a missing piece from a set. If you buy authentic set from legos they will send replacement parts for free but it can take a while. If you are like myself you want to complete the project before moving on to the next one so this spare set is a great addition to any builder.

Great pieces seem to be good quality

I am building a Mould King 4x4 R/C Truck set 18009, and the front wheel hubs did not turn, which is one of the primary functions of wheel hubs, besides holding the wheel rims so the tires do not fall off the truck. These replacement wheel hub parts are working VERY WELL so far. They click together and they hold AND THEY TURN FREELY without issue. I will know more about the quality once I attach the tires to the 3 connector pins and see how the truck handles driving it. I hope tires do not fall off. That is a true test. I got these parts quickly, so it might be a good idea to buy these part collections to have them ready when building a Mould King or Reobrix or CADA kit and you are having problems with missing parts or parts that do not connect and stay connected. This solution is faster than waiting for customer service and weeks for the replacements to show up. Ordering these parts allows for less interruptions to my building, so I can hopefully get replacement parts while I continue working on the truck with these parts as the "backup" instead.
