- P-Series Performance Design: Specifically engineered for high-revving, high-stress applications, this series exceeds the capabilities of standard Original Equipment (OE) bearings, offering a superior margin of safety and longevity for performance builds.
- Critical Engine Component: As a connecting rod bearing, its function is vital: it supports and lubricates the connection between the connecting rod and the crankshaft, actively reducing friction and absorbing the enormous dynamic forces of the engine's power stroke.
- High Load-Bearing Capacity: Built to withstand demanding conditions, this bearing is suitable for a wide range of uses, including motorsports, heavy-duty utility, and high-output street performance.
- Undersize Precision Fit: The .25MM undersize is a key feature, indicating it is designed to fit a crankshaft journal that has been repaired by being ground 0.25mm smaller. This precision fit allows for optimal oil clearance, which is crucial for maximizing engine performance and lifespan.
- Direct Replacement for 6.7 Powerstroke: While it is a direct fit for the 2011-2024 6.7 Powerstroke engine, its P-Series designation makes it the preferred component for performance and rebuild applications that demand more than an OE part can offer.
- Engine Crankshaft Undersize (in.): 0.010 in.
- Engine Crankshaft Undersize (mm): 0.25mm
- Bearing Material: AL-5
- Dowel Pin Hole: No
- Narrow Bearing: No
The Clevite CB-1953AP-.25MM P-Series Undersized Rod Bearings are not just replacement parts—they're an essential upgrade for any 6.7 Powerstroke (2011-2024) application. These P-Series performance engine connecting rod bearings are engineered for the rigorous demands of high-performance engine builds, whether you're dominating on the racetrack, tackling heavy-duty workloads, or optimizing a street performance machine. A connecting rod bearing is a foundational component that sits between the connecting rod and the crankshaft, tasked with a critical job: supporting and lubricating the rod while reducing friction under the immense forces of combustion. The P-Series design provides a significantly higher load-bearing capacity and superior durability compared to standard stock bearings, making them the ultimate choice for engines that experience high RPMs, extreme stress, or heavy loads. The .25MM designation confirms their precision fit for a crankshaft journal that has been ground 0.25mm undersize (approximately 0.010 inches), allowing you to salvage a worn crankshaft and create the tighter, more precise clearances demanded by a true performance build.
