Cylinder Sleeve 4.0820 Bore 6.875 OAL 4.052 ID

The Melling Cylinder Sleeve CSL1155 is a precision-engineered cast iron sleeve designed for AMC V8 engine rebuilds and performance restoration. With a 4.082-inch bore diameter and 6.875-inch overall length, this OEM-specification sleeve restores worn cylinder walls to factory tolerances, enabling proper piston-to-wall clearance and ring seal integrity essential for compression and combustion efficiency.

Manufactured from cast iron with a 0.094-inch wall thickness and 4.052-inch inner diameter, the CSL1155 cylinder sleeve delivers the hardness and thermal conductivity required for sustained high-heat engine operation. The 4.272-inch outer diameter provides the proper press-fit surface for secure installation in the block bore. Melling's casting process ensures dimensional consistency across the sleeve length, critical for piston travel and ring wear patterns. This single sleeve replaces one damaged or worn cylinder, making it ideal for selective honing jobs where bore damage is localized rather than systemic across all cylinders.

Engine builders and machine shops rely on Melling sleeves for AMC V8 restorations—whether rebuilding a Javelin, Hornet, or Gremlin performance engine. This sleeve suits both street and light competition applications where core engine integrity is non-negotiable. Proper installation requires honing to final bore size after sleeve press-fit and adequate cooling time to ensure block-to-sleeve metal bond integrity.
