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.

I havent gotten a chance to see how the extruder works yet, although it seems to be of good quality and installation was easy. The issue I have is that the bed springs are too long for an Ender 3 pro, even though the description says they should be able to fit. I will try to trim them but they are made of very tough metal and are difficult to cut.

Product was exactly as described, works fantastic. I would recommend anyone having issues with leveling or extruder skips to purchase this kit. Its fantastic

very good quality and good upgrade for my ender 3 pro

Springs are too long

The aluminum parts are well made and the upgraded bed leveling wheels are great! I used a little dot of Elmers glue between the bottom of the screw heads and the metal bed plate to keep them from spinning. It didnt stick to the metal super well, but it made enough friction to keep the screws steady.

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.

Great product! Easy install and great quality.

I upgraded these on my Ender 3 Pro to ease maintenance. The stiffer springs are a HUGE improvement over the stock springs and rarely need adjusting now The extruder I saw as insurance knowing that the stock plastic extruder arm is a potential failure point

The plastic extruder that was included with my machine was wearing down within the first few weeks. This is one of my first upgrade it was incredibly helpful. Note: this set did not include the yellow springs
