Supertech VW 2.0L ABF Rally GrA 83mm Bore 3.3mm Dome Pistons - Set of 4 (895052-50) (Excl Rings)

If you're building a high-performance VW 2.0L ABF engine for rally or racing, these Supertech forged pistons are a solid foundation. They're designed to handle the increased stress and heat of demanding applications, giving you the reliability you need when pushing your engine to its limits. The 83mm bore size is specific to the ABF engine, and the 3.3mm dome height is engineered to work with specific compression ratios, so it's important to match these with your cylinder head and camshaft setup for optimal performance.

These pistons are forged from high-strength aluminum alloy, a common choice for performance applications because it offers a good balance of strength and weight. Forging makes the piston material denser and more resistant to deformation under extreme pressure and temperature compared to cast pistons. The 83mm bore is the standard size for the ABF engine, meaning these are intended as a direct replacement for the stock bore size, though they are designed for the rigors of performance builds. It's important to note that these pistons do not include piston rings, so you'll need to source those separately. Ensure you select rings that are compatible with the 83mm bore and the piston groove dimensions.

When installing these pistons, proper clearance and lubrication are critical, especially in a performance engine. Always refer to the manufacturer's installation instructions and consult with a qualified engine builder to ensure correct assembly and break-in procedures. These pistons are sold as a set of four, ready to be installed in your ABF engine.
