I bought this kit mostly for the springs.I ended up making some sleeves that go inside the springs because they still didnt want to stay vertical even with the flat ends. They are firmer thought and work nicely. The extruder top was just a bonus, and its really nice. Only drawback there is it should have instructions or at least a diagram. I ended up going back to the stock adjuster wheels. The aluminum ones are made well, but they are too slick imo. The stock ones have better knurling and are lighter weight.

Already unimpressed. Just got the package, opened it up and everything looks the part, minus the springs...because theyre not there.

So much better than the original parts.

Almost everything in this is great. The only complaint I have are the springs. They are about 8 mm too long. The extruder is a huge improvement over my stock one. The red wheels are a nice touch and the feeder is great! If I were to buy over again, I would look somewhere else with a better spring.

If you have purchased a 3-D printer and looking to do a quick and easy upgrade tomorrow not recommend anything better definitely makes 3-D printing much more enjoyable and having to constantly level the bed or having to deal with it not feeding properly no issues at all. Highly recommend.

I have 4 printers. 2 with a similar red kit and this kit which is the silver ones. The metal extruders seem to be the same or same quality on each however this kit has better springs for the bed. These springs are a little beefier and seem to hold the build plate level a little better. Less micro adjusting needed. I would recommend to get some Capricorn tubing with this kit as well and you should be set

Only received 3/4 springs and the extruder hardware in the bags does not match what was advertised, I think with the plastic extruder hardware I have can make it work. Two stars for the quality of the parts that did arrive being decent. Caveat emptor, you are also on your own to figure it all out, no instructions included.

installed the extruder upgrade and halfway through the first print the screw that hold the bearing came loose . the aluminum was poorly machined and the screw came out with the threads .... basically its useless .... seller wont respond to inquirey .

This is an awesome kit to buy for your Creality. These are all actual Creality parts and install flawlessly. Even if you buy it just to have spare parts, this is a good deal. I like the aluminum leveling wheels opposed to the plastic primarily for the looks but I’m sure they will last the life of the printer. The extruder is awesome it even works with TPU, I had it running up to 60mms with TPU and didn’t have an issue.

I like the metal upgrade, springs are great, and the twist nuts are cool but the extruder set was missing a bolt. I was able to reuse old bolts that I had, but be aware, you will be one short.
