Absolutley Awesome

The Tekno pinions are absolutely awesome. They have a larger set screw so you can get them nice and tight and the steel is VERY hard. I ran one on my Serpent SRX8e that has a steel spur gear for over a year, and the pinion has minimal wear.

Go to Gears

Great pinion gears. I have a 16t and an 18t for my Kraton EXB and they aren't showing any signs of wear, even after the pinion slid back on the motor shaft and machined a nice hole in my motor mount. I'm going to say that if this pinion gear slipped, any other pinion would have and it was not the fault of the pinion. The grub screw feels solid and won't likely strip anytime soon. These will be my go to pinion from now on.

I run these with Tekin motors in my EB48 and SCT410. The picture really doesn't do this product justice as the teeth are sharp and aggressively beveled to allow for a precise mesh. Get one of these and try it, you'll be switching out all of your mod 1 pinions to Tekno after using one--trust me.

Replaced Kraton 6s V5 pinion with this after it chipped. M2.5 grub screw really lets you torque this thing down with confidence.
