Cylinder Sleeve BBC w/ Tall Deck 4.590 Bore

The Cylinder Sleeve BBC w/ Tall Deck 4.590 Bore from BRODIX is engineered for serious big-block Chevy engine builders and performance enthusiasts pursuing maximum displacement and durability in tall-deck applications. This precision-manufactured sleeve restores bore diameter and cylinder wall integrity in high-performance builds where factory castings have reached their limits or where overboring requirements exceed safe limits. Whether you're rebuilding a race engine, stroker project, or heavily modified street engine, this tall-deck sleeve delivers the foundation needed for reliable power.

Manufactured by BRODIX—a trusted name in performance engine components—this 4.590 bore cylinder sleeve is precision-engineered to exacting tolerances for optimal ring seal, proper oil control, and minimal blowby. The tall-deck configuration accommodates the extended deck height found in modern big-block Chevy castings, allowing builders to maintain proper piston-to-deck clearance and combustion chamber design. At just 1.95 lbs and compact dimensions (5.1 x 5 x 7.5 inches), the sleeve is lightweight yet durable, designed to withstand extreme cylinder pressures from supercharging, nitrous, or naturally aspirated high-rpm applications. The 4.590 bore size provides excellent clearance margins for serious overbore situations while maintaining robust wall thickness for sustained reliability.

This cylinder sleeve is ideal for engine builders tackling big-block Chevy tall-deck platforms in competition, street rod, or marine applications where cylinder wall damage, previous overboring, or displacement requirements demand sleeve installation. Professional machine shops and experienced DIY builders will appreciate the precision fit required during installation—proper honing, press fit specifications, and deck surface preparation are critical for leak-free sealing and longevity. Verify that your tall-deck block, piston package, and ring set are compatible with the 4.590 bore diameter before ordering to ensure a complete, functional build.
