Redrex 365mm T8 Z Axis Lead Screw Z Rod Stainless Steel Threaded Rod with Brass Nut Z-axis Upgrade Kit for Ender 3 V2/Ender 3 V2 Neo/Ender 3 Pro/Ender 3/Ender 3 Neo/Voxelab 3D Printer

Works great

These rods will not fit a Creality Max no matter what Google tells you. LOL. The quality is excellent. I put these on a flat surface and used a square with them. they are very straight. I could not find the slightest curve. Even though they were not usable for my purposes I will keep them and use them on a future project.

Ive been looking for quite some time for a replacement z axis rod for almost stock ender 3 due to mine Ireceived with a WAY bent z axis rod and wasn't ready to step up to a ball rod which yes is better quality but didn't need that much power for this printer, All in all great product, packaging could of been better though.

I’m only knocking off a star because of the fact that the item was shipped in a literal bag. From the manufacturer this wasn’t on amazons part. Because of it like most delivery services are they basically toss your items like they owe them money. Anyways the part works great and fixed my z banding issues.

I've had a bent z axis for years and this solved all my z axis woes. I suggest buying this with a few other things so they put it in a darn box. Mine came in 2 plastic bags stapled together inside an amazon bag. It was still straight though, so I guess it's fine.

It's a thing of beauty when you hold the lead screw vertical and the brass slowly spins its way down. Glad I bought 2. Be sure you have lube because these are dry. I'm very happy with the quality.

Ok. I saw comments about the rod being bent upon delivery, and guess what???.. Mine was bent as well, and even though it arrived in a box, so that is curious... This rod is unusable, so had to get one elsewhere. Just be cautious... Others are receiving theirs bent, and so was mine, and it was not in a bag, it was in a box.

Used this to replace a bent lead screw on my Ender 3. Works fine.
