Industrial Injection Dodge 12V Mahle Piston .040 Oversized Coated Champ. Fly Cut

These Industrial Injection Mahle pistons are built for Dodge 12V engines and are .040 inch oversized, meaning they are designed to replace stock pistons that have been worn beyond standard bore dimensions. The 'Champ. Fly Cut' designation indicates a specific valve relief cut into the piston crown, which is crucial for ensuring proper clearance with the valves in performance or modified cylinder heads. This attention to detail in the piston crown design helps prevent piston-to-valve contact, a common issue when increasing compression or using aftermarket camshafts.

Constructed with durable materials and featuring a special coating, these pistons are made to withstand the rigors of a high-performance diesel engine. The .040 inch oversize is a common requirement when rebuilding an engine that has previously been bored out, or when dealing with significant cylinder wall wear. Mahle is a well-known name in piston manufacturing, and Industrial Injection has selected these for their ability to handle increased cylinder pressures and temperatures found in modified 12V Cummins engines. The precise machining of the valve reliefs is a key feature for builders aiming for optimal engine health and performance.

When undertaking a rebuild with these pistons, it's important to ensure your engine block has been properly machined to the correct .040 inch oversize bore. You'll also want to confirm compatibility with your specific cylinder head and camshaft combination, especially if you have an aftermarket setup. This set is designed for 6-cylinder applications and represents a solid choice for a robust engine overhaul.
