SBM Thumpr Hyd. Cam 287TH7

The SBM Thumpr Hyd. Cam 287TH7 from COMP CAMS is a high-performance hydraulic roller camshaft designed for serious small-block engine builds. This camshaft is ideal for applications requiring aggressive power delivery and reliability, particularly in demanding conditions such as elevated boost pressures and high-RPM competition environments. Users who depend on precision mechanical systems will appreciate the importance of camshaft selection in defining engine character and responsiveness.

The 287TH7 designation indicates a hydraulic roller design optimized for street and strip applications. This camshaft delivers controlled valve events with minimal lash variation and reduced maintenance compared to flat-tappet alternatives. Hydraulic roller technology effectively absorbs shock loads during valve operation, which protects valve train components and enhances longevity, making it a critical choice for high-stress tactical or field applications.

This camshaft is particularly beneficial for small-block engines, including LS and SBC variants, and is suitable for street, marine, and competition applications. The cam's geometry and lobe profiles are calibrated for 287 degrees of duration at 0.050" valve lift, producing a broad powerband that supports both aggressive acceleration and steady throttle response. COMP CAMS' commitment to manufacturing precision ensures that this camshaft meets the demands of performance enthusiasts.
