Overview
As a long time builder of high FPS setups, I’m used to working with Torque Up (TU) and Infinite Torque Up (ITU) gear sets, both Helical and standard. When I decided to build yet another high FPS gearbox I decided to try some of the newer brands.
SHS is one such brand. Since their introduction in 2008-2009 they’ve made a name for themselves as a quality manufacturer. So when I saw a ITU 32:1 gear set for a low $20 USD I figured it couldn’t hurt to try them since most ITU gear sets cost nearly $100 USD.
Externals Review
Externally there’s never going to be much to say about a gear set. Anything can look nice, but the quality is what counts.
However, a few things can be noted about the gears.
The spur gear and sector gear are both clearly marked as SHS and the gear ratio 32:1, meaning every 32 turns of the bevel gear is equal to one turn of the sector gear. This is an extreme gear reduction ratio meant for creating high torque and strength at a loss of speed. A high speed gear set for instance might be a ratio of 16:1.
Internals Review
Without costly testing equipment it’s hard to test the true durability of the SHS gears, however most websites claim to withstand a modest M140-M160. A basic visual examination shows the gears to at least appear, on the surface, to be well machined and cash. I was especially impressed with the bevel of the teeth to allow for more clearances between the gearbox or other gears’ surfaces. Each gear seemed to be solidly assembled.
Performance
Initial testing was done with a Guarder SP150 (Guarder’s equivalent of a SystemA M150). The initial shot was clean and smooth. The gears shimmed easily and sounded smooth upon pulling the trigger. Since they are standard and not helical gears they are a bit louder than normal, however, they were still a good bit quieter than I was expecting.
Long term testing is required, but I am impressed by SHS quality.
Editor’s Note 2017: After 5 years and countless rounds, the gears are still holding up to a SP150 and haven’t needed any serious servicing since the installation.
Final Thoughts and Upgradeability
When it comes to ITU gears I generally prefer the Helical gears as they are stronger and less likely to break due to the design of the teeth. But I have to hand it to SHS, their non-helical gears are just as good.
Externals Score: 10/10
While it would be cool to see fancy colors flying around in a gearbox, the base fact is these are work parts. So there’s not much to mark up or down.
Internals Score: 10/10
I hesitantly give them a 10 out of 10, but as of the initial testing period the SHS gears feel and perform solidly. Until they break I will gladly give them the maximum credit possible.
Editor’s Note 2017: A 10/10 is well deserved for the quality and price.
Overall score: 10/10
For the price there is no better ITU gear set. At $20 USD their prices can’t be beat. They say you get what you pay for, and if there’s any truth in the saying you can expect early failure. However, the SHS seem to be well manufactured and able to take the punishment of extreme performance. So for now it gets top marks. But again, further test is required. An extended update will be provided as testing continues.
