SEMA 2025: New SBC Camshaft Lineup From AFR

Air Flow Research (AFR) used SEMA 2025 to spotlight something many Small Block Chevy builders have been waiting for. The company, known for its industry-leading CNC cylinder heads, rolled out a new series of SBC camshaft profiles built to match the airflow, RPM range, and character of AFR’s Eliminator CNC and Enforcer As-Cast heads. Engine builders have long paired AFR heads with aggressive valvetrain setups, and AFR has now filled that gap with its camshaft designs produced in partnership with Andrews Products.

By releasing these grinds as a complete system solution, AFR ensures that SBC enthusiasts get a combination engineered to work together from the start. Both Stage 1 and Stage 2 cams are retrofit hydraulic roller designs built for high RPM performance, track-focused engines, and serious street combinations. Each profile is backed by dyno data gathered through AFR’s in-house development program.

Premium 8620 Steel Construction

One of the standout updates for this new SBC camshaft series is the move to 8620 steel cores at no additional cost. This material upgrade strengthens the cams for high RPM conditions, power adder work, and demanding street builds. AFR highlights the core’s hardness and stability, noting that it improves consistency in the grinding process and enhances long-term wear resistance.

AFR’s decision to standardize 8620 on every cam position makes these profiles reliable choices for builds that see frequent passes, long session times, or heavy throttle. Heat-treated surfaces maintain durability without sacrificing ductility, a balance valued in both professional and hobbyist racing environments.

Stage 1 SBC Camshaft Details

The Stage 1 cam (P/N 6015) was designed to complement AFR’s Eliminator CNC heads while maintaining broad high RPM capability. Duration at .050 lands in the 22X/23X range, with lift reaching the 0.53X to 0.54X area when paired with factory 1.5 rocker arms. Switching to 1.6 rockers bumps lift to approximately 0.56X intake and 0.58X exhaust. A 112-degree lobe separation angle gives this SBC camshaft a responsive but stable personality suited for track-focused engines.

This cam is compatible with computer-controlled applications, requires valve springs, and features a three-bolt gear attachment.

Stage 2 SBC Camshaft Details

For builders who want a bit more power, Stage 2 (P/N 6016) extends the intake duration into the 23X range while keeping the same 112-degree lobe separation. The lift increases slightly to 0.54X with 1.5 rocker arms, matching the Stage 1 exhaust lift and offering more intake area. With 1.6 rockers, lift rises into the 0.58X territory on both sides.

Like Stage 1, this SBC camshaft is designed for high-RPM strip applications and uses the same retrofit hydraulic roller format with premium 8620 steel.

A Focused Expansion Of AFR’s Valvetrain System

With these camshafts, AFR extends its commitment to helping builders get the most from their Small Block Chevy combinations. The profiles are engineered specifically to complement AFR head designs, giving builders a proven, dyno-tested path toward consistent power production.
