The MELLING CSL1126 is a stock-replacement cylinder sleeve built for engine rebuilders who need to restore a worn or damaged bore to factory spec. It carries a 4.500-inch bore, a 7-3/4-inch overall length, and a 4.470-inch inner diameter, with a 4.690-inch outer diameter that drops into a properly bored block. Cast from iron and ground to tight tolerances, this liner gives shops an economical way to recover a cylinder without scrapping the casting. It fits straightforward rebuild work rather than high-performance applications, making it a practical choice for anyone working through our engine parts catalog.
MELLING manufactures the CSL1126 using centrifugal cast iron, a process that produces a dense, uniform grain structure throughout the wall. The sleeve carries a wall thickness of 0.094 inch (3/32 inch) and a Brinell hardness rating of 241 to 293, giving it the strength to handle press-fit installation and the wear characteristics expected of a stock liner. Per manufacturer specifications, these liners are held to tolerances as small as one-half of one-thousandth of an inch, and the outer diameter is finished with centerless grinding for true roundness and consistent dimensions sleeve to sleeve. That consistency matters when you're fitting a liner into a freshly bored block and want a predictable interference fit. It pairs naturally with a fresh piston ring set during a rebuild.
Reach for the CSL1126 when a cylinder has been scored, cracked, or bored beyond serviceable limits and you want to save the block. After the bore is machined to accept the 4.690-inch outer diameter, the sleeve is pressed in and finish-honed to match your piston and ring package. It's a stock-grade liner, so it suits daily-driver rebuilds and restoration work rather than boosted or race builds. Match it with the right cast pistons and round out the job with components from our engine bearings selection for a complete bottom-end refresh.
The CSL1126 has a 4.500-inch bore, a 4.470-inch inner diameter, and a 4.690-inch outer diameter. Overall length is 7-3/4 inches (7.750 inches) with a wall thickness of 0.094 inch (3/32 inch). These figures come from manufacturer specifications and let you confirm fit before machining the block.
No. The CSL1126 is a stock-replacement grade liner intended for quality rebuilds and restoration work. It carries a Brinell hardness of 241 to 293 and is built for daily-driver and standard rebuild applications rather than boosted or competition engines.

Yes. The block must be bored to accept the 4.690-inch outer diameter, after which the sleeve is press-fit into place and finish-honed to match your piston and ring package. This is standard procedure for any press-in cylinder liner.
