This set is a must have for any Ender series printer. The original springs that come with your printer are not that strong which leads the bed to be become unlevel very easy, sometimes even during a single print. I used to have an adjustment wheel left on the counter under my printer because it worked itself loose during the print. This set of springs will take care of mist of the leveling concerns you may face. The wheels themselves arent bad that come toil the printer but the red ones look and feel a lot better. The all metal extruder is well worth the money and time it takes to replace. The original one is plastic with a metal tube for the filament to travel thru. After 6 weeks of daily printing of PPE, the filament, even with a filament guide cut thru the tube and started to cut thru the plastic feeder. This will eliminate that problem all together. You have to be aware that the gasket/screw that holds the boded tube to the extruder is NOT the same one/size as the original plastic one. You will need to use the same size that is attached to your hot end (the other side of the boden tube) Get extras of that as well...... Overall, this is a first paid for upgrade that you should do on your machine. While you are at it, get some extra boded tubes form Capricorn.

Excellent upgrade for the ender 3. The springs are very stiff and keep the the bed rock steady. The aluminum wheels are mostly for looks but they do feel a little nicer and definitely look better than the stock plastic ones. The extruder is an aluminum version of the the stock unit. It works very well and bolts on really easily since it is the same layout as stock. The only complaint I have is that they left out the wire guides that came on the stock unit so you have to get creative if your wires are drooping down. Overall this is a very good upgrade for the price and should last a long time.

Item works very well and helps keep the bed leveled. Bought because my extruder wore down and didnt feed right. Only issue I had is it was cumbersome to install and the instructional video wasnt super helpful.

Crap

The larger springs are a good upgrade to help with the bed maintaining its level. However, like many other reviewers, there was a missing part in this package. They didnt send the extrusion pin that the extrusion clip pivots on. I can reuse the plastic one that came with my printer but it kind of defeats the purpose of buying a metal replacement kit. Edit: User error on my part initially. The extrusion pin was already in place instead of shipped loose like the other parts. I only noticed it when I went to use the existing plastic pin and saw the metal pin was already there. The upgraded parts work well, the larger springs definitely help keep the bed level better than the stock springs where I had to relevel the bed after nearly every print. The new wheels do rub though, so you will probably want to print some spacers for those. The filament is also rubbing hard against the new extruder gear and creating dust accumulating on the extruder. It isnt much and it hasnt affected my prints so far but I am going to try to replace the tube with a quote-on-quote frictionless bowden tube and see if that fixes the problem. Overall, I do recommend this upgrade kit and for the price youre not risking much.

Great quality! Way better than what originally came on the machine

Quick and easy to swap out the bed springs and leveling knobs. However, I was missing the feeder replacement that sits on one of the motors and the threads on one of the parts wasnt machined properly so I was unable to screw the movable arm for the feeder assembly in place. Need to contact creality or the seller for a replacement.

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

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

Excellent kit to upgrade printer with metal parts
