From Stock to 1,000+ HP: Darton Sleeves in a Gen 4 LS Block
In this video we’re installing Darton dry sleeves into GM Gen 4 aluminum blocks here at Boostline Performance.
This is a critical step in building a strong, reliable foundation for any high horsepower setup. These stepped sleeves are designed to prevent sleeve drop and handle the demands of boosted and nitrous applications, giving you the strength and durability serious builds require.
Everything you see is done in-house to ensure proper fitment and consistency, so every block is ready to perform under pressure.
If you’re planning a high horsepower build, this is where it starts.
