PowerPack Forged Piston Set

This set of Mahle PowerPack pistons is engineered for the 2.8L 24V VR6 engine, offering superior strength and performance over OEM components. Precision forged from 2618 alloy, these pistons feature a low expansion rate aluminum construction. Mahle has incorporated forged side reliefs and a slipper skirt design to reduce overall weight and minimize friction, contributing to improved engine efficiency. The pistons feature ultra-flat ring grooves, which are crucial for promoting excellent ring seal and preventing micro-welding during the break-in process. Additionally, every set comes with Mahle's exclusive Grafal skirt coating. This coating not only acts as an anti-friction layer but also provides impact-absorbing qualities, which help to reduce piston noise and decrease stresses on the piston skirt, enhancing durability. With a bore of 81.5mm and a stroke of 90.3mm, these pistons achieve a 9.0:1 compression ratio when used with a 164mm rod. They are designed to be used with 20mm wrist pins, so ensure your connecting rods are compatible. This complete set includes rings and pins, making it an excellent choice for enthusiasts seeking increased strength and a lightweight piston solution with an OEM fit and finish.
