Block Guards help prevent catastrophic engine failure. Blockguard is a must for turbo, NOS and supercharged applications.
Our blockguard is custom design using computer Aided Drafting for precision and CNC milled from 6061 Aluminum, and are proudly made in the China.
Using a block guard on your engine turns your open deck into semi-closed deck with machined coolant passages that promote critical coolant flow especially where the cylinders join, other brand block guards may create destructive hotspots around cylinders, and increase the chances of engine failure.
Our block guards are machined to be slightly oversized to compensate for the cylinder walk flaw common in open-block designs, and to ensure a water tight seal around each cylinder when pressed in your block.
