"Heavy, 23 grams for the piston alone, but fine for most builds. No issues, surprising for an Angel Custom internal part.

"Strong piston, i like it
Important dont fit on krytacs gearboxes!
by Jeffrey C. on 09/27/2018
"Note this piston has 14 teeth minus one tooth (one being shaved off), it only has 13 teeth for the sector gear to pull on so you need to shave off the last tooth on your sector gear to use this piston. Other than that this piston is one of my favorites for extreme speed or franken torque builds. If you want something else than SHS then go with this but be warned this piston may not fit in all v2 gearboxes because of the guides on the side may not mesh with the guides within the gearbox. I know this because it wont fit in my XR-5 gearbox but the SHS pistons fit in it perfectly. All in all, this piston is a good choice for any build, This can fit in APS silver edge gearboxes and many more it was just the CSI gearbox in the XR-5 I found it wont fit.
