Billet Aluminum-Steel Sleeve Cylinders

 The OEM cylinder heads are cast .These engine cylinders are CNC machined from billet aluminum and feature additional fins and fin surface area to provide the added cooling capacity desired for all racing applications. The steel sleeves provide enhanced performance by maintaining a more rigid and consistent bore shape, improving ring seal and increasing cylinder life under harsh racing conditions. Specify proper cylinder size and case bore/spigot size by part number with exact size required (because there are size variations on each part number) with an email along with order.

*** NOT AVAILABLE AGAIN UNTIL  8/ 1/2017. Sorry for the tease, these are made on a limited run. A small deposit will insure your order. Send us an email for details.
