5150 Xtreme Duty Cylinder Sleeves, also known as cylinder liners, are centrifugally cast, ductile iron cylinder sleeves.

Benefits of engine sleeving include:

• Increased bore size: Sleeving your engine gives the opportunity to increase bore size for higher displacement and increased engine capacity, resulting in more power and torque
• Increased strength: Iron sleeves are stronger than alusil when subjected to high power, high stress applications, making the cylinder wall much less likely to crack under high performance conditions
• Custom cylinder wall thickness: With the ability to install a thicker cylinder wall, prepare your engine for high performance modifications including high boost applications
• Improved heat dissipation: By transferring heat more quickly and efficiently, sleeved engines are able to better withstand the higher temperatures associated with high performance applications
• Improved engine longevity: By reinforcing critical areas and transferring heat quickly and efficiently, the risk of catastrophic engine failures under high stress applications is greatly reduced
• Compatibility with performance modifications: sleeved blocks are better equipped to handle a wide range of high performance modifications such as high compression pistons, aggressive cam profiles and big boost

Priced per set of 8 sleeves. Perfect in combination with CP-Carrillo/5150 Pro-Xtreme Forged Piston Sets!
