High Quality Valves
Unlike our competition, we do NOT modify existing valves in our builds. Instead we use an all new valve with better materials, that do not have common high-heat separation issues.
Crank Gear
Welding
We TIG weld the crank
gear in place to prevent
the gear from spinning,
which throws off timing
and bends all 32 push
rods.
We do NOT use the aftermarket fix of larger clearance bearings in our builds, which causes low oil pressure. Instead we use our own proprietary bearings that allow for perfect alignment.
