This is a performance kit for 212cc Non-Hemi Predator engines, built for modified-class kart racing. It centers on a .308 high-lift racing camshaft with extended duration, for modified engines targeting up to 7000 RPM. The cam needs upgraded valve springs and reinforced valvetrain components, and the kit includes 26lb valve springs.
The rotating assembly gets a 3.308" heavy-duty connecting rod with a bearing set. A GX220 70mm flat-top piston kit with rings and wrist pin raises the compression ratio. A lightweight machined magnetic flywheel reduces rotational mass.
A gasket and seal package is included for a full rebuild-level seal, along with an F7TC spark plug and a magnetic drain plug set. The kit is recommended for modified racing applications only.
