The Modify Modular Speed Up Gear Set for Ver.2/Ver.3 is a drop in gear set that is good to go right out of the bag. The gears are held together and fall right into place, this item comes with metal bushings, and no shimming is required. This is the best way to change the gears in your Version 2 and 3 gearbox and save time on shimming. This is a "High Speed" gear set, which means that the gear set is designed for low power springs.

I have several set of these Modify modular gears, in high speed and high torque, as well as the SMOOTH series of Modify gears, also in high speed and high torque.
Awesome gears, if you have a 100% Tokyo Marui compatible gearbox. Most cheap Chinese cloned guns don't....they copy the Classic Army/Systema reinforced gearboxes (which, by the way, have the reinforcement in all the wrong spots - by the spring guide and around the bushings/gear axle holes. Anyone who's ever repaired a broken gearbox knows they only break in 2 places: either the cast metal pin that hold the trigger block in place snaps off from pulling too hard on the trigger, or they crack right at the front around the cylinder windows from an overpowered spring, dry-firing, or the extreme cold. Gearboxes never break at the rear, or around the bushings...). Additionally, many cheap Chinese cloned guns do not have true 6mm bushing holes...the tolerances are more open (6.1mm) because of sloppy quality manufacturing QC. Modify does sell a 6.1mm bushing kit for those of you trying to install these gears in older cloned Chinese mechboxes, like the first run JG's.
You need to use these in a real-deal Tokyo Marui gearbox, or any other one that does not have all the fake-ass reinforcement crap on the inside. Once you have that sorted, these gears are excellent (although not as nice as the modify SMOOTH-series gears). Mine have lasted well over 100,000 rounds pulling a Modify MS100 spring and using an 11.1v 20C lipo pack.
- Never shim again!
- Excellent quality gears
- Very fair price for what you get
- Only fit in actual TM-style/non-reinforced gearbox.

For: Modify Modular High Speed Gear Set for V2/V3 (6mm Gearbox)
It's a great idea, but it doesnt fit in my reinforced SRC gearbox, in the picture you'll notice that at the bottom left there is part of the metal piece that connects everything together sticking out...well, inside my gearbox (and just about every other gearbox i've ever owned) there is solid metal between the spur gear and the back of the gearbox/spring guide, making it impossible to place the gear set inside at all. Looks like now i have to pay extra money to buy a new gearbox shell that is compatible with this gear set.
Great concept if you have a lot of money to spend on Airsoft, like me ; )
Doesn't fit in certain gearboxes - making it a waste of $80
Some of you may know that I have been working on my airsoft guns for approximately five years now. From AEG's to GBB's. I've always had a reason to repair or upgrade a few guns here and there. I've been playing Airsoft for about six years now. I usually prefer the fast paced CQB games, but I do play Milsim games when asked to. I started playing airsoft at a place called Airsoft Playground before Tac City North was around. On days that I do play, the most common type of Airsoft Gun I see on the field is an AEG. A lot of people, back then, were not very knowledgeable on the internal of an Airsoft gun. To start off, different airsoft guns have different versions gearbox. However, the types of parts inside are all the same. One of the most important parts is the gears, which operate the internal of the airsoft gun.
Airsoft GI sells a wide variety of gears from different companies suitable for your limits and desires. To those just looking to increase the durability of your gun, Echo 1 Performance Gear Sets have different ratio gear sets from speed to torque. Continuing up the ladder, for those that are looking to increase both performance and durability, Siegetek gears are the way to go. The type of material Siegetek uses as well as the precise specification of every tooth spacing and diameter on the gear shaft are what give them their name. Siegetek, former RiotSC, has manufactured gears for some time now but it is only recently that Airsoft GI has finally carried these amazing products. Whether, you want a high speed setup or a designated marksman rifle that shoots at 600+ feet per second, their selection of gears can handle them all. The only downside is that currently, they are only offered to airsoft guns that use a Version 2 or a Version 3 gearbox.
Don't think Echo 1 and Siegetek are the only two brands that I would recommend. Airsoft GI carries gears from manufacturers such as Modify, Bravo, and Prometheus, which are great gears as well. Some manufacturers such as SHS, X- Hightec, Combat Squad, etc. also manufacture great gears; however, in my opinion, they are not as well made as Siegetek. Once you have decided what gear set you want, next is the installation. For those that are just beginning to learn to upgrade their gun, its important that you find a qualified technician, whether its a recommendation from a friend or a store tech and you trust. The techs at Airsoft GI are highly qualified for any work done to any gun.
When I work on my airsoft guns, I try to depict the best way to achieve maximum efficiency while maintaining my desired velocity and rate of fire. I would choose a gear set with a given ratio to calculate an approximate rate of fire output on a certain Lithium Polymer battery. I would then polish my gears to reduce friction between the shafts and bearings. By polishing those critical areas, any grease and lubricant applied will be evenly distribute along those surfaces, and prevent them from going to unwanted places.. I use a different lubricant for the compression parts, but that will be another article..
In conclusion, by determining the right set of gear and reducing as much friction on the surface as possible, you could achieve a reliable,
long lasting setup. But most importantly, unless you are working on your own guns, itís important that you have the right technician for the job. I am Marq, be safe, and get out and play airsoft.
Please Note: Please be respectful and do not use any profanity. Any questions regarding the removal of the orange tip will be deleted.
Would it work?
Would these gear be able to pull an m120 spring if a super high torque motor like the Tienly Gt-35000 were installed? Thanks.
