Capable of handling over 1,500hp, the engineers at PTG have developed a steel sleeve in conjunction with Darton Sleeves that is made to work with stock or PTG pistons.

All engine blocks go through a scrutinizing process to ensure all tolerances are above OEM AMG standard. These are the follows steps taken to validate the engine block.
- Deck Height and Machining of Deck
- Check Line Hone
- Physical and Chemical Check for any Imperfections or Cracks
- Machine and Install Darton Sleeves
- Electro & Vibration Check for Sleeve Sink
- Precision Hone to exact sizes down to the .00001"
- Line Hone Check & Hone down to the .00001"
If you are looking for the absolute best solution to handle and sustain the highest horsepower levels or if you simply need to repair a damaged cylinder, this is the choice for you.
