About Brian Crower

Brian Crower, Inc. (commonly known as BC or #RunBC) is one of the most respected names in the sport compact performance world. Headquartered in El Cajon, California, the company was founded with a clear mission: to fill the gap in the high-performance aftermarket for late-model internal engine components — delivering race-proven quality at prices accessible to enthusiasts and professionals alike.

Founded by Brian Crower of Crower Cams, BC is dedicated to serving the sport compact community with high-quality, affordable, and readily available internal engine upgrades. That philosophy has never wavered, and it remains the foundation of everything the brand produces today.

Engineering Built for Performance

Designed for today's sport compact engines, Brian Crower specializes in stroker kits, camshafts, and valve train components, creating complete performance packages for increased horsepower, torque, and engine reliability. Rather than offering isolated components, BC engineers its products to work together as a system — so every part complements the next for maximum gains on the street or track.

BC uses state-of-the-art CNC grinding to ensure precise tolerances in every part. On the camshaft side, small diameter camshaft grinding wheels on certain BC cam part numbers — including Honda B and K Series, Nissan SR20, and Mitsubishi 4G63 — deliver added valve action for greater cylinder fill rates. The result is a lineup of engine camshafts that can meaningfully transform engine output across a wide range of popular platforms.

Completing the valvetrain picture, BC valve springs by PAC Racing are wound from only the highest grade, super clean, chrome silicone alloy and feature proprietary processing procedures for consistent pressures. These engine valve springs are designed to handle the elevated RPM demands that come with aggressive cam profiles. Paired with BC's engine valve spring retainers, premium grade 6AL4V titanium retainers are 100% RC checked for hardness — ensuring that every component in the valvetrain is up to the task under sustained high-RPM abuse.

Platform Coverage & Proven Results

Brian Crower Inc. specializes in high-performance engine internals and cam regrind services for a variety of automotive brands including Honda, Nissan, Toyota, Subaru, and more. Whether you're building a K-series Honda for road racing, a turbocharged Subaru EJ, or a Mitsubishi 4G63 drag car, BC offers engineered solutions for your specific platform.

All Brian Crower products are rigorously tested and dyno proven to deliver peak performance. Brian Crower stroker kits, camshafts, crankshafts, rods, and valve spring kits have been used in some of the fastest cars on the track today. That track record — built over years in the most demanding motorsport environments — is why BC parts are trusted by builders who need reliability as much as outright power.
