High-Performance Engine Reinforcement with Darton Sleeves

When pushing your GM LS-series engine to the limit, block integrity is paramount. The Darton Sleeve Modular Integrated Deck (MID) cylinder sleeve is the industry-leading solution for high-horsepower builds, providing the strength and durability required for forced induction or high-compression applications.

Technical Specifications

  • Bore Size: 3.985 inches, precision-engineered for optimal ring seal.
  • Height: 5.800 inches, providing full-length support for the piston stroke.
  • Material: High-tensile strength steel for maximum thermal stability and wear resistance.
  • Design: Modular Integrated Deck (MID) design to improve head gasket sealing and block rigidity.
  • Wall Thickness: 0.170 inches, offering a robust barrier against cylinder wall deformation.

The Darton MID system is renowned for its ability to turn a standard LS block into a bulletproof foundation for extreme performance. By replacing thin factory cylinder walls with these high-grade steel sleeves, you eliminate the risk of cracking or distortion under extreme boost or nitrous loads. This is a critical upgrade for any serious engine builder looking to achieve consistent, reliable power. Whether you are building a track monster or a high-performance street machine, these sleeves provide the peace of mind that your block can handle the heat. For all your engine component needs and expert advice, look no further than GGCRACING.
