BBM Xtreme Solid Roller Cam XR292R

The BBM Xtreme Solid Roller Cam XR292R from COMP CAMS is a mechanical roller camshaft engineered for high-performance Mopar B and RB-series engines seeking aggressive valve lift and extended duration. This camshaft is designed for enthusiasts and engine builders who demand increased airflow, improved cylinder filling, and peak power output in the 3,500 to 6,600 RPM operating range. Solid roller cam technology eliminates valve float at high RPMs, making this unit ideal for race applications, street performance builds, and naturally aspirated engine combinations where reliable, repeatable valve actuation is critical.

The XR292R delivers 0.582-inch intake lift and 0.588-inch exhaust lift with a 292-degree intake and 297-degree exhaust duration specification, all ground on a 110-degree lobe separation angle. This aggressive profile maximizes volumetric efficiency and promotes scavenging in the combustion chamber, translating to greater horsepower and torque production across the mid to high RPM band. The solid roller design uses precision-machined lobes and hardened steel construction to withstand extreme valve spring pressures and repeated high-load cycles without degradation. The mechanical actuation method ensures zero valve lash variability, providing consistent performance lap after lap or pass after pass.

This camshaft is compatible exclusively with Mopar B-series (small-block) and RB-series (big-block) engine platforms, making it an essential upgrade for vintage Dodge, Plymouth, and Chrysler muscle cars as well as modern restomod projects. Installation requires proper valve spring selection, rocker arm geometry verification, and potentially upgraded pushrods to accommodate the increased lift specifications. Engine builders and serious enthusiasts recognize the BBM Xtreme Solid Roller Cam XR292R as a proven solution for unlocking maximum displacement potential while maintaining durability under sustained high-RPM operation. For sale as a single unit, this camshaft represents the foundation of any competitive small-block or big-block Mopar performance engine build.
