Carrillo D7020-8 High-Performance Diesel Piston Set 6.6L Duramax .020 Over 15:1 Compression

The Carrillo D7020-8 high-performance diesel piston set is manufactured from 2618 T-61 alloy for structural support and durability, and comes completely hard anodized to withstand turbocharging, supercharging and nitrous. This 8-cylinder piston set features a 4.075-inch bore (.020 oversize), 1.946-inch compression height, and 15:1 compression ratio, making it ideal for high-boost applications on 2001-2016 GM 6.6L Duramax engines.

Advanced Performance Features:

• Forged from 2618 material with tapered pin bosses for increased strength
• Hard anodized coating to withstand extreme heat and provide additional scuff resistance
• Tapered pin boss design fits factory and aftermarket rods, .070 deep valve reliefs, radius bowl shape
• Forged side reliefs and milling to reduce overall weight, lightening the rotating assembly and reducing stress
• Torture tested and withstood 1800+ horsepower at the tires

Complete Kit Includes:

• 2mm coated top ring, 2mm second ring, high tension 3mm 2-piece oil ring
• Heavy duty .285 wall cold extruded chromoly wrist pins
• 5115 steel pins and .082 Kramm Lox
• Radius oversized valve reliefs for increased valve lift

The 15:1 compression ratio is typically used with compound turbos or high-performance single turbo systems due to the increased volume of air these turbo systems provide. The anodized coating on ring grooves and entire piston protects against severe heat, preventing groove wear from increased cylinder pressures and temperatures that could compromise dimensional stability and ring seal.
