Repl Cyl Sleeve Brodix SBC 4.110 Bore 4.282 OD

The Repl Cyl Sleeve Brodix SBC 4.110 Bore 4.282 OD by DARTON SLEEVES is a precision engine rebuild component designed for serious marine and performance boating applications. If you're rebuilding a small-block Chevy powerplant for high-output duty—whether for freshwater tournament fishing or saltwater cruising—cylinder sleeves are non-negotiable when restoring or upgrading worn block decks. This replacement sleeve fits Brodix SBC cylinder heads and delivers the bore geometry and material integrity required for engines that demand reliability under sustained load and high RPM.

DARTON's wet-sleeve design features a 4.110-inch bore diameter with a 4.282-inch outer diameter, engineered to provide superior cooling and thermal control in liquid-cooled systems typical of marine engines. The precision bore ensures proper ring seating and piston clearance, while the OD dimensions guarantee a tight, secure fit within the Brodix block casting. At 1.93 pounds, each sleeve combines material density with dimensional accuracy—critical factors for maintaining compression integrity and preventing blowby that can degrade engine efficiency and marine performance over extended operating seasons.

This cylinder sleeve is ideal for engine builders and restoration specialists working on Brodix SBC platforms used in performance boats, bass rigs, and high-output marine applications where engine longevity directly impacts your time on the water. Whether you're replacing a single worn sleeve or completing a full short-block rebuild, ensure you order the correct quantity for your specific block configuration. Installation requires precision honing and proper sealing procedures; consult your engine builder or refer to Brodix technical specifications for torque values and assembly protocols specific to your application.
