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.

The springs are amazing, add in BL or CR touch and youll almost never have to level your bed again. The extruder upgrade is needed no matter what. The oem plastic WILL break.

It lasted only a short time before the threads wore out where the screw holds the wheel in the handle.. had to put the old handle back on temporarily.. I know the one I got wasn’t worth …. Maybe just this item .. but it broke …

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.

Awesome addition. I bought mostly for the tighter springs, but when i went to replace the extruder covers i noticed that the plastic pieces i was replacing were cracked and about to break! highly recommend these parts. note: you will have to move your Z-stop up a bit due to the change in springs and wheels.

So nice To replace original plastic one with a beautiful metal one, same goes for the bed leveling wheels.

Amazon has a serious counterfeit product problem. After purchasing another of these kits its clear this is a counterfeit kit I received this time from this seller. Who knows if Amazon just grabs knockoffs off the shelf vs legit products or if sellers know theyre selling counterfeit products but this time it appears to be real. Hardware is tarnished and cheapish, fitment is sloppy, having the two side by side makes the knock off obvious. May the odds be ever in your favor.

This “upgrade” came up as being a deal and discounted when I purchased my Ender 3 V2. First off the springs included with this kit are too long. It makes the bed too high. The extruded upgrade was well made but never seemed to do anything better than the original and in fact never worked quite right on my printer. The only thing I really used in this kit was the metal leveling knobs. That’s the only reason I’m giving this 2 stars. The rest was just a waste of money for me.

** Update ** Actually heard back from the seller the next day, they apologized for the mistake and made it right. Took a little while because the kits were out of stock. But received a brand new complete kit and was finally able to install it. Works beautifully. I couldn’t be happier, and now I have a couple spare parts for in the future! Got my kit today, impressed with the previous reviews. Missing a key piece (#2 Extrusion Pin). Without that, this kit is useless.

Good upgrades for 3-D printers.
