  • Rated for 400+ FPS
  • Extremely strong forged Japanese steel
  • Made in Japan
  • Redesigned bevel gear for improved semi-auto response
  • Precision machined, quiet gear mesh sound
  • Perfect pairing with the Prometheus anti-reversal latch and pinion gear
The proven EG Hard Gear series with over 10 years of service are precision machined, made in Japan, heat treated, and forged to the highest standards. Due to such precision machining, you can expect a much quieter gear mesh sound even at higher FPS and fire rates. Tested on the industry standards of a 11.1v 20c lipo battery with a 40k high torque motor on a MS135 spring (400+ FPS), the EG Hard Gear set withstood over 10,000 rounds of continuous usage with no visible wear.

Reliable, precise, and proven.

"Having purchased these gears a few months ago, and I am pleasantly surprised at their performance. These are by far the highest quality gears I have ever dealt with and the R.O.F. is off the charts. Right now I am hitting 40~50 bullets per second, this is WITHOUT a D.S.G. (duel sector gear). When well shimmed, these gears are dead silent and, with proper modifications, these gears will help transform your A.E.G. into a polarstar eating machine. (almost) To help justify the cost, these gears are extremely durable and will last you a lifetime. Overall I highly recommend these gears to anyone making a high-speed build.

"I am running these gears with a Systema m130 spring and a Matrix Godzilla super high torque motor. one of the major bonuses of these gears is that they come with shims (I did a high dollar custom build and didn't wan't to spend extra). The gears shim nicely and I haven't had a problem with them yet.

"Great gears! Very good quality. I was previously using SHS 12:1 gears, which I was getting 39 rps with a shs high torque high speed motor. And when I took the shs gears out the one screw on the sector gear was lose as hell. Which created a wobble and started to kill my bearings. So I popped some umbrella bearings in and these gears with perfect shimming fired it a few times. Noticed it sounded slower so I hooked my gate titan to my phone and I dropped to 29 rps. which I am ok with I guess. I thought from the previous review I'd be getting 40-50 like he said but I dont think that's the case obviously lol. So at least I have some gears that will last and bearings that won't blow up from crappy gears.
