Industrial Injection 89-93 Dodge 12V Mahle Piston .040 Oversized Coated Tops / Skirts

If you're rebuilding the engine in your 1989-1993 Dodge with the 12-valve Cummins, a quality set of pistons is crucial for getting your truck back on the road reliably. This set from Industrial Injection uses Mahle pistons, known for their solid construction and precise manufacturing. These are .040 inch oversized, meaning they are designed to replace pistons that have worn beyond their standard size, allowing for a fresh bore and a tight seal.

What sets these pistons apart is the coating on the tops and skirts. The coated tops help manage heat and reduce detonation, which is important for keeping your engine running cool and preventing damage under load. The skirt coating is there to reduce friction as the piston moves up and down in the cylinder. Less friction means less wear over time and potentially a small improvement in efficiency. Mahle pistons are well-built and designed to handle the demands of a diesel engine, and Industrial Injection has chosen them for this performance-oriented rebuild kit.

This set includes pistons that are .040 inches larger than the factory standard. This means your engine block will need to be bored to match this size for a proper fit. It's always a good idea to confirm the exact specifications and requirements with your machine shop before ordering parts for a rebuild. Remember, these pistons are not CARB approved and cannot be shipped to California.
