Skunk2 Ultra BMF TLRC Stage 1.5 Camshafts - Honda B16A/B16B/B17A/B18C

Upgrade your Honda or Acura B-series VTEC engine with the Skunk2 Ultra BMF TLRC Stage 1.5 roller camshafts. Built from billet 8620 alloy steel with advanced roller lobe profiles, these camshafts open and close the valves faster than a factory sliding-style valvetrain, delivering a broader power band and improved efficiency across naturally aspirated and forced induction applications.

Key Features

  • Billet 8620 alloy steel camshaft construction
  • Advanced BMF roller lobe profiles for faster valve actuation
  • Stage 1.5 profile balances street usability with stronger high RPM gains
  • Valvetrain rated stable up to 12,000 RPM with proper supporting components
  • Suitable for both naturally aspirated and forced induction B-series builds

Frequently Asked Questions

Do these camshafts require upgraded valve springs?

Yes. Skunk2 recommends using Ultra BMF TLRC rockers along with upgraded valve springs and retainers to support the higher lift and RPM capability of this camshaft profile.

Can these camshafts be used on a naturally aspirated engine?

Yes. These camshafts are designed to work on both naturally aspirated and forced induction B-series engines.

What is the difference between Stage 1, Stage 1.5, and Stage 2?

Stage 1 favors street drivability, Stage 1.5 balances street usability with stronger high RPM gains, and Stage 2 is the most aggressive profile intended for dedicated high-performance or track builds.

Is professional installation recommended?

Yes. Camshaft installation requires proper valve clearance setting, valvetrain component matching, and tuning, and is recommended to be performed by an experienced engine builder.

No. This camshaft set is not CARB legal and is not for sale or use on pollution controlled motor vehicles in California.
