Heavy-Duty Piston Set for High-Performance Builds

When you're putting together a serious 12-valve Cummins build and need pistons that can take a real beating, the Industrial Marine Big Bowl Race Pistons are built to answer that call. Designed specifically for 1989–1998 RAM 2500 and 3500 trucks, these .020" oversized pistons aren’t just a rebuild item—they’re a major performance upgrade engineered for high-horsepower, high-boost setups where reliability is non-negotiable. One of the first things that stands out about these pistons is the .100" fly cut valve reliefs. If you're running a big cam with higher lift, you know clearance can become an issue fast. These pistons solve that right out of the box, giving your valves the breathing room they need without sacrificing strength or durability. It’s a small but critical detail that shows these were designed with serious builds in mind.

Built with High-Quality Components

The pistons also feature chamfered tops, which help prevent swelling at high temperatures and reduce the chances of scuffing the cylinder walls under heavy load. That translates to smoother operation, less wear over time, and better longevity even under aggressive driving or towing conditions. It’s the kind of extra protection you want when you’re pushing more fuel, more air, and a lot more power. Up top, you’ll find a thermal barrier coating specifically designed for high-output applications running nitrous, turbos, or superchargers. This coating helps retain heat inside the combustion chamber longer, improving combustion efficiency, boosting torque, and ultimately squeezing more horsepower out of every drop of fuel. It’s a performance edge that’s especially valuable in racing or heavy competition settings where every advantage counts.

Coated Design

The skirts of each piston are coated in a ceramic composite that handles extreme pressure—over 350,000 PSI—and continues to lubricate even at temperatures beyond 1600°F. This coating drastically reduces friction and wear during high-load, high-speed operation, helping your engine stay strong and smooth even under the toughest conditions. Plus, with a cured film thickness of .001" or less, there’s no need to adjust piston-to-wall clearance during installation. Each kit comes complete with six pistons, along with rings, wrist pins, and clips, making it a true drop-in solution for a complete bottom-end refresh or performance build. Whether you’re setting up for drag racing, sled pulling, or just building a monster street truck, the Industrial pistons give you the confidence to push harder without second-guessing your parts.
