INDUSTRIAL INJECTION PDM-03513CC.020 DODGE PERFORMANCE PISTONS - 1989-1998 5.9L CUMMINS 12-VALVE - .020 OVER

Stronger, cooler, cleaner combustion for your 12-valve build. Industrial Injection's Coated & Chamfered (.020 over) piston set is engineered for high cylinder pressure and heat. Each set includes pistons, rings, wrist pins, and clips for a true drop-in kit after machining the block to .020. Coated crowns help manage heat and the skirt coating reduces friction and scuffing; chamfered tops ease loading at TDC.

FAQ

The kit includes rings, pins, and clips. Your block must be bored/honed to .020 over and measured for correct clearances.

They feature a thermal barrier crown coating to manage heat and a skirt coating to reduce friction/scuffing in high-load use.

With higher-than-stock lift or tight timing, fly-cutting (.100) is recommended to ensure piston-to-valve clearance.

Use MAHLE HS4068 (upper set) for the 12-valve top end and CS4068 (lower set) for the bottom end.
