Supertech VW 2.0L ABF Rally GrA 82.5mm Bore 3.3mm Dome Pistons - Set of 4 (895052-00) (Excl Rings)

In this set, you get four Supertech 82.5mm bore pistons designed for the VW 2.0L ABF engine, specifically for Rally Group A applications. These pistons feature a 3.3mm dome, which is crucial for achieving the desired compression ratio in a performance-oriented build. They are forged from aluminum, a material known for its strength and light weight, making it ideal for the stresses of racing or high-output street use. This set is sold without piston rings, so you'll need to source those separately to complete the assembly.

The forged construction means these pistons are significantly stronger and more durable than cast pistons. This is essential for engines that will see high cylinder pressures and temperatures, such as those found in rally cars or heavily modified street machines. The 82.5mm bore size is specific to certain engine configurations, and the 3.3mm dome helps control the combustion chamber volume. When rebuilding or upgrading your 2.0L ABF engine for demanding use, these pistons offer a solid foundation for improved performance and reliability under stress.

It's important to note that these pistons are not CARB approved and cannot be shipped to California. You will need to ensure you have the correct piston rings that match the 82.5mm bore and the specific ring groove dimensions for these pistons. Proper installation, including careful measurement and assembly by a qualified mechanic, is critical for the longevity and performance of your engine.
