Built for Big Injectors and Even Bigger Power

When you're running a serious build on your 2004.5–2007 6.0L Powerstroke, the stock high-pressure oil pump simply won’t keep up. That’s where the RCD Thumper II comes in. Designed for trucks equipped with 225CC injectors or larger, this pump is built to handle what other HPOPs can’t. It delivers 30 percent more oil volume than the original Thumper I and supports up to 300CC conventional injectors, making it one of the highest flowing single-pump options on the market. If you’re chasing big horsepower numbers, this upgrade gives your injectors the oil pressure they need to maintain consistent power under heavy throttle, high boost, or extended pulls. Whether you're building a competitive race truck or a heavily modified street rig, the Thumper II provides the support system your engine needs to perform at its peak.

Engineered for Demanding Builds and Long-Term Reliability

What sets the Thumper II apart isn’t just the output—it’s the attention to detail in the design. RCD internally ports each unit for improved oil flow, modifies the housing for proper camshaft clearance, and installs a high-displacement cam to maximize performance under load. These pumps are remanufactured to exacting standards, using all new check valves, heads, and shafts to ensure durability and long service life. This isn't a universal, one-size-fits-all part—it’s purpose-built for high-horsepower applications that demand more from every component. And while it installs as a drop-in replacement, this pump is anything but ordinary. It’s not recommended for builds running smaller than 205CC injectors, which says a lot about the level of performance it's designed for. Backed by a one-year warranty and a reputation for dependable power delivery, the Thumper II is a must-have for any 6.0 Powerstroke owner who isn’t afraid to push their setup to the limit.
