6448 Hot Racing 45#Steel 50T 1 Mod Hardened Steel Spur Gear for Traxxas 1/10 E-Revo 2.0 VXL 1/5 X-Maxx Maxx 1/7 XO-1 (50T)

I have been running this 50T spur gear from Hot Racing in my X Maxx all summer long with perfect results. It's worth mentioning that I show my models no mercy! I removed the TRaxxas motor mount pin system and manually adjust gear mesh. I also have the Hot Racing metal motor mounts that help reduce flexion. I also employ the Traxxas metal motor mount bolt washer kit that allows me to really crank the bolts down lowering the chance of movement. Finally, I modified the OEM motor shaft to accept Arrma "D" shaped pinion gears. You just need to file the flat spot on the motor shaft back towards the motor a couple of millimeters.These things combined give me excellent spurt and pinion gear lifespan.

Great quality, fit perfectly on my XRT. Very strong it has held up to a lot of bashing with zero issues. Would buy again

Love hot racing products. This is a huge upgrade from the stock steel spur gears

I’m not entirely sure these are actually hot racing brand. I bought one here on amazon and another from Amain Hobbies. The Amazon one has not hot racing packaging and comes with generic hardware. The amain hobbies one came in actual hot racing packaging and came with 12.9 grade hardware. I also noticed they look slightly different in the machining. The one from Amain hobbies has a wider tooth face and overall looks slightly higher quality. Now maybe it’s just different packaging because Amazon buys in bulk and it’s just from a different batch. I’m not sure, so far so good and I have stripped it. But if I have issues I will update this review.TL,DR so far so good, much better than stock. but I’m not 100% sure these are genuine Hot Racing brand.

Nunca sobra tener este tipo de repuestos siempre los vas a necesitar en este tipo de monster car

Great product works perfect thankyou

Showed up on time and this is a great gear if you’re running mod1 , they pair great with ProTek pinion gear . Have that set up in 2 of my stock motor C-Maxx’s with max6 ESC’s . Very strong even have a 20/54 set up in my 6s MAXX with a Max6 in it

*** UPDATE 3/23/24 *** I am retracting my last submission. Unfortunately, I think quality control or material has gone waaaaay down since the pandemic. I ran the gears for the second time with a complete total of 30 minutes. No jumpibg, smooth throttle, as I am experienced I understand how to avoid rookie mistakes. This is plain bad management. Their cratmanship has gone way down. Although Virtavon is very expensive for what we are buying, at least it lasts. I bought 3 vitavon sets totaling $175 just to have spares and I have yet to see a single mark on a single tooth. Save your money and buy Vitavon. Or avoid Traxxas altogether.(Old review and doesn’t apply any longer) - What can I say. Hot Racing is one of the best. Literally drove my brand new XRT out front on the road, completely babying it and 15 minutes into it, screech, gears gone. lol. It’s a direct replacement for the XRT and has been amazing. Honestly I immediately took out the stock gears and ran those. No issues yet. Traxxas should be embarrassed by allowing such crappy material in a $1000 car. Not an arena fan but at all but neither of my kratons have done that.
