BBC Hydraulic Roller Cam XR282HR-10

The BBC Hydraulic Roller Cam XR282HR-10 is designed for serious big-block Chevrolet builders who seek reliable, street-responsive performance without the complexity of traditional solid-roller setups. This hydraulic roller cam is ideal for engine builders aiming to balance power gains with drivability, providing the efficiency of roller technology combined with the forgiving nature of hydraulic lifter systems.

Hydraulic roller cams operate using oil pressure to automatically adjust lash, which eliminates the need for frequent valve clearance adjustments that are common with traditional flat-tappet designs. The XR282HR-10 profile is optimized for mid-range torque and top-end horsepower, making it versatile across a wide RPM band—perfect for street applications where smooth throttle response is as important as peak power. BBC's precision manufacturing ensures tight tolerances on lobe profiles and base circles, reducing wear on the cam and lifter surfaces while promoting consistent valve timing throughout the engine's operating range.

This cam is specifically designed for 1965-and-newer big-block Chevrolet engines (427, 454, and related variants) equipped with hydraulic lifters, making it an excellent choice for restomods, street cruisers, or weekend warriors looking to unlock their BBC's true potential.
