Piston Ring Set, 92mm, 2 X 2 X 4, for Aircooled VW

OVERVIEW

When it comes to rebuilding your air-cooled Volkswagen engine, the integrity of your combustion seal is everything. These Grant 92mm piston rings are engineered specifically for enthusiasts who demand longevity and consistent compression out of their high-performance or increased-displacement builds. Whether you are running a classic Beetle on the street or a rugged sand rail in the dunes, these rings provide the critical barrier needed to prevent blow-by and ensure that every ounce of power generated in the combustion chamber is transferred directly to the crankshaft. Grant has been a staple in the VW industry for decades, and this G1295 set continues that legacy by offering a precision fit that handles the unique thermal expansion characteristics of air-cooled cylinders. Don''t let a weak seal compromise your engine investment; trust a brand that has been powering Volkswagens for generations.

This specific ring set is designed for the popular 92mm bore size, a favorite among builders looking to increase displacement to 1835cc or 1914cc without moving to the more extreme 94mm bores. The 2mm x 2mm x 4mm configuration is the standard for many aftermarket 92mm piston kits, providing a robust surface area for heat dissipation and superior oil scraping. By utilizing high-quality materials that resist tension loss even under the intense heat of a magnesium or aluminum crankcase environment, these rings help maintain a clean burn and significantly reduce oil consumption. This is vital for the longevity of your Type 1 engine, especially in high-load scenarios. When you choose Grant rings from Appletree Automotive, you are choosing a component that has been proven in the most demanding environments, ensuring your VW stays on the road and out of the shop.

PRO TIPS

1. Precision Ring Gapping is Non-Negotiable

Ring gapping is arguably the most critical step in your engine assembly process. Even though these are high-quality Grant rings, you MUST check the end gap of each ring inside the specific cylinder it will be living in. For a 92mm air-cooled application,
