14 metal teeth piston NARROWED RACK

Rack width is narrowed to 6mm from 7mm. 

In some setups depending on piston rails in the gearbox a 7mm could scratch your cylinder. People used to taper the rack themselves to prevent this issue but in 2026 we prefer to stock 6mm wide racks instead. A rack width of 6mm will not scratch your cylinder. Losing 1mm also drops weight which is important for high speed builds.

This is what we run for most builds when you request a custom aeg build or upgrade.

We can super glue or jb weld rack to piston upon request, which of the 2 adhesives you want to use just let us know.
