Dart BBC Cyl Sleeve 4.590 10.200 Deck Height

The Dart BBC Cyl Sleeve 4.590 10.200 Deck Height from DARTON SLEEVES is a precision cylinder sleeve engineered for big block Chevy engine builds requiring exact bore diameter and deck height specifications. This cylinder sleeve delivers the bore accuracy and dimensional consistency critical to high-performance engine assembly, making it essential for builders targeting tight tolerances and reliable long-term operation.

The sleeve features a 4.590-inch bore, 4.740-inch outer diameter, and 6.770-inch height, all engineered to work within a 10.200-inch deck block configuration. These specifications are critical for maintaining proper piston clearance, ring seating, and combustion chamber geometry. The precision casting and finish of DARTON SLEEVES cylinder sleeves ensure minimal runout and wall thickness consistency, which directly impacts ring seal quality, blow-by reduction, and engine longevity. For engine builders working with Dart blocks, matching the correct sleeve to your deck height eliminates guesswork and ensures proper component fit during assembly.

This sleeve is purpose-built for big block Chevy enthusiasts, race teams, and machine shops performing engine rebuilds, restorations, and performance modifications. Whether you are refreshing a vintage engine or assembling a custom big block, verifying the correct deck height specification—in this case, 10.200 inches—is non-negotiable. Using a sleeve matched to your block's deck height prevents issues such as improper piston protrusion, gasket compression errors, and combustion seal failures. Builders relying on DARTON SLEEVES trust the brand's reputation for dimensional accuracy and quality control across the small block and big block Chevy market.
