Wiseco Volvo S60R B5254 -13cc Dish 1.2008x3.2874 (83.5mm) Custom Pistons SPECIAL ORDER

What you get in this special order kit are five custom forged pistons from Wiseco, designed specifically for the Volvo S60R's B5254 engine. These aren't your average pistons; they're built from 2618 aluminum, a material chosen for its strong tensile strength, making them ready for the demands of serious racing and performance builds. Each piston features a -13cc dish, an 83.5mm bore, and a 30.50mm compression height, with a 0.9055-inch pin diameter. This set is intended for European 2.5L 20V applications.

Wiseco puts a lot of thought into these pistons. They're forged and machined right here in the USA, ensuring a high level of control over the manufacturing process. You'll find precision ring grooves, an anti-detonation groove, and other features aimed at improving ring seal, which is crucial for consistent power and engine health under stress. The crown of each piston is fully machined, and they come with an ArmorGlide skirt coating. This coating helps reduce friction, resist seizure, and even makes operation quieter, all while handling heavy to severe duty performance applications. The design also includes forced pin oiling to keep the wrist pin properly lubricated.

Because these are custom pistons, they are a special order item and are not CARB approved, meaning they cannot be shipped to California. If you're building a high-performance Volvo engine that needs to handle serious power and stress, these Wiseco pistons are a well-built option designed for that purpose.
