Mahle 42216CP Engine Piston Ring Set

Overview

MAHLE 42216CP is a premium engine piston ring set built for shallow groove applications with a 3.7798-inch bore diameter. It combines carbon steel, cast iron, and stainless steel ring materials with a plasma-moly face coating to support controlled friction and oil management in the engine.

Compatible With Chevrolet Silverado 1500, Chevrolet Suburban, Chevrolet Tahoe, GMC Sierra 1500, GMC Yukon, and GMC Yukon XL applications listed below. This part number, 42216CP, is a fitment-specific replacement for select 2014-2022 GM trucks and SUVs.

Key Features

• Premium-grade piston ring set for engine rebuild and repair work
• Plasma-moly face coating for reduced ring wear under operating load
• Carbon steel top ring, cast iron second ring, and stainless steel oil ring assembly
• Standard oversize configuration with shallow groove sizing
• Engineered around OE-driven requirements for friction control and oil consumption management

Detailed Description

MAHLE 42216CP is designed for engines that require a standard-size piston ring set with shallow groove dimensions and a 3.7798-inch bore. The ring package uses a carbon steel top ring, cast iron second ring, and stainless steel oil ring assembly, along with a plasma-moly face coating to support stable sealing performance and wear resistance. In GM applications such as Chevrolet Silverado 1500 and GMC Sierra 1500, this ring set is matched to the fitment data for 2014-2022 model years, with additional coverage for Chevrolet Suburban, Tahoe, GMC Yukon, and Yukon XL. The 42216CP part number should be verified against the engine build and ring groove specification before installation.

MAHLE piston rings are developed around OE requirements and focus on lowering friction, controlling oil use, and extending service life. That engineering approach is reflected in the 42216CP ring materials and coating selection, making it a practical choice for engine service where dimensional accuracy and ring design matter.

What It Helps Address

• Excessive oil consumption caused by worn or incorrect piston rings
• Loss of cylinder sealing during engine rebuilds
• Increased friction from aged ring surfaces
• Compression issues related to ring wear or mismatch
• Service replacement needs for shallow groove piston applications

Installation Notes

Confirm bore diameter, ring groove style, and engine specification before installation. The fitment data includes Chevrolet Silverado 1500, Chevrolet Suburban, Chevrolet Tahoe, GMC Sierra 1500, GMC Yukon, and GMC Yukon XL applications, so the 42216CP should be matched to the exact engine configuration listed for the vehicle. Clean ring grooves thoroughly and inspect cylinder condition during engine service.

Quality Assurance

MAHLE positions this piston ring set as a premium component built to OE-driven standards. The 42216CP reflects the brand's focus on friction reduction, oil control, and longer service life in engine applications.
