Sleeved block

Sleeved block

All blocks are sleeved with our in-house custom designed flanged, double-thick, sleeves and installed with a proprietary nitrogen shrink fit process, insuring proper contact is maintained between engine block and cylinder sleeve allowing for optimal heat transfer to the engine cooling jacket. All blocks come with machined decks with proprietary finish and all bores are semi-finished to allow STD bore size

With over 4000 sleeves installed and zero sleeve failures, rest easy knowing your engine has the best protection available.
