What is the compression height and pin size for these pistons?

These Mahle pistons have a compression height of 1.304 inches and use a 0.927-inch pin. This is important for ensuring proper piston-to-valve clearance and deck height in your engine build.

What material are these pistons made from and why is it important?

The pistons are made from 2618 aluminum alloy. This is a strong and durable material commonly used in performance applications because it can handle high temperatures and pressures without deforming, which is crucial for boosted or high-compression engines.

Are these pistons compatible with all LS engines?

These pistons are specifically designed for Chevrolet LS 5.3L 325cid engines and are compatible with LS1/2/6 style cathedral port heads. It's always best to confirm your specific engine's head type and displacement before purchasing.
