The BRODIX BBC Cylinder Sleeve delivers precision bore restoration for big-block Chevrolet engine builders demanding exacting tolerances. This steel sleeve is purpose-built for BRODIX aluminum engine blocks, providing the foundation for cylinder wall integrity in high-performance applications. Whether you're repairing a damaged bore or preparing for a stroker build with increased displacement, this sleeve maintains the dimensional accuracy that proper ring seal and piston clearance require. Engine builders working on competition motors or street performance projects will find this component meets the demands of serious horsepower applications.
BRODIX engineers this cylinder sleeve with a 4.590-inch bore diameter and 7.625-inch height, dimensioned specifically for big-block Chevrolet architecture. The 4.725-inch outside diameter and 0.067-inch wall thickness provide the structural rigidity needed under sustained high-load conditions. Steel construction ensures consistent thermal expansion characteristics and resistance to the cylinder pressures generated in forced-induction or nitrous applications. The sleeve's machining tolerances allow for proper interference fit installation, creating a secure bond with the aluminum block material. This design approach addresses the challenges of maintaining bore geometry in lightweight race blocks where thermal management is critical to engine longevity.
This cylinder sleeve serves builders working on dedicated race engines, bracket cars, and street-strip machines where bore damage has compromised the original cylinder walls. The sleeve-and-block combination offers the weight savings of aluminum construction with the durability of steel cylinder surfaces. We stock BRODIX components alongside our full selection of parts and accessories for builders completing comprehensive engine projects. Pair this sleeve with quality machine work from a reputable engine shop to ensure proper installation and final honing for your chosen piston package.

This cylinder sleeve is designed exclusively for BRODIX aluminum big-block Chevrolet engine blocks. It will not fit factory cast-iron blocks or aluminum blocks from other manufacturers. Always verify your specific block casting number and sleeve pocket dimensions before ordering.
The sleeve arrives with a 4.590-inch bore diameter. With a 0.067-inch wall thickness, there is limited material available for overboring. Consult your machine shop about maximum safe bore size based on your target piston diameter and required wall thickness for your application's power level.
Proper installation requires professional machine shop equipment. The sleeve is typically pressed or shrink-fitted into the block's sleeve pocket, then bored and honed to final size. This is not a DIY procedure—precision tooling and measurement equipment are necessary for correct installation.
This listing is for a single cylinder sleeve sold individually. For a complete V8 engine rebuild, you will need to purchase eight sleeves. This allows builders to order only the quantity needed for partial repairs or complete block sleeving projects.
