Read! *by J***N on Reviewed in the United States on May 1, 2022* This is a good replacement set for a real Titan. However! These gears and lever work with the genetic Titan but will require and additional item and a little work. I have replaced entire China titans more times that I can mention but reason it usually due to worn arm or worn feed gear as after a few hundred hours the gear teeth get worn down. You can file them to get a little more bite but this gear set is the answer. You WILL need 5mmx10mmx3mm bearings to make this work as the shafts on this gear are smaller than the china ones. There is no 5mmx10mmx3mm bearings. So your choice is 5mmx9mmx3mm these will fit this gear perfect but not the hole in the china plastic frame. They are 1mm to small so your gear will wobble. It WILL work if your tighten the thumb screw for tension really tight. Or if you find or print a 1mm shim. Or you can go with 5mmx10mmx4. This best choice. As it fits the hole and the shaft perfect but sits out about .5mm to far I used a solder iron to heat bearing and push it further into the plastic or you could remove some of the plastic to make it work. Now for about 15$ you have real hardened Titan gear metal arm and better bearings in your genetic Titan. I highly recommend the metal arm and the hobbled gear. This is good quality set. I’m buying 5 more. ### ⭐⭐⭐⭐ 4.0 out of 5 stars fits as shown *by T***N on Reviewed in the United States on June 25, 2024* I got what I ordered, and it fits my machine as advertised. ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars Perfect fit for a Titan extruder (Tronxy XY-2 Pro) *by M***K on Reviewed in the United States on October 1, 2023* I went from a pattern of gaps in my prints to solid, even lines. I didn't realize my extruder gear had worn down on my Tronxy XY-2 Pro Titan. Be mindful that the Idler Arm does not fit the Titan extruder that comes with the one from Tronxy. But this is a turnkey solution for folks who are getting under-extrusion but have checked everything else (bed, hotend, teflon tube, nozzle). --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.com.kw/products/679796085-upgraded-3d-printer-extruder-level-gear-and-idler-arm-groove](https://www.desertcart.com.kw/products/679796085-upgraded-3d-printer-extruder-level-gear-and-idler-arm-groove) --- *Product available on Desertcart Kuwait* *Store origin: KW* *Last updated: 2026-05-18*
