Street Cars – Race Cars – Drag Racing – Road Racing
Simply the BEST way to protect your High Horse Power block from cracking!!! The Cylinder Support System is a proven method of strengthening open deck engine blocks while maintaining OEM integrity. It prevents cylinder cracking, walking, and bellmouthing. Unlike traditional aftermarket cast iron sleeves, the support ring is made from aircraft grade 6061-T6 aluminum. This material will actually pull post combustion heat away from the chamber, decreasing intake charge temps, unlike thick cast iron which tends to heat soak because of poor heat transfer properties.
No Sinking – No Leaking – No Mainline Distortion – No Overheating
The Cylinder Support System process is NOT to be confused with the industry known “blockguard.” Why? Because it does not rely on the loose tolerance and taper(draft angle) of the factory casting. The Cylinder Support System process involves precisely machining the water passage, to accept our precision machined billet 6061 support rings. Our precision fit gives equal support pressure around the cylinders from the top of the support ring to the bottom of the support ring. Even the most finely filed/sanded blockguards cannot compete with the precision of our high quality CNC milling machines.
