BC adjustable cam gears deliver the easiest way to dial in more horsepower and/or torque without getting underneath the valve cover, disassembling the engine or dealing with onboard electronics.
🔩 Built for Power, Precision, and Reliability
Each BC8830-1 Adjustable Cam Gear is CNC-machined from billet 6061-T6 aluminum, ensuring perfect balance, lightweight strength, and resistance to deformation at high RPM. The outer gear ring is anodized for durability, while the included ARP fastener bolts provide superior clamping force and long-term reliability — even under race-level stress.

These gears are engineered to handle the demands of high-RPM, high-boost environments — perfect for 2JZ-powered Supras, Aristos, IS300s, and custom swaps.
BC gears are CNC machined from aerospace grade, 6061-T6 billet aluminum for ultimate tensile strength. Easy to read, laser etched face features micrometer style markings for precise adjustment (up to 10 degrees in each direction) and quick tunability.
🔧 Installation & Tuning Simplicity
Installation is straightforward for any experienced tuner or engine builder. The BC8830-1 gears are designed to bolt directly to factory 2JZ camshafts using the included ARP hardware.
Installation Overview:
-
Remove the factory cam gears.
-
Align and install the BC8830-1 adjustable cam gears.
-
Torque ARP bolts to manufacturer specifications.
-
Set cam timing to baseline, then adjust ± degrees for desired performance.
-
Verify timing with a degree wheel and tune for maximum efficiency.
Always perform final tuning on a dyno or with a professional ECU calibration to extract the full benefits of adjustable timing.
Each hub is held down by six ARP made, Grade-8 hex bolts for maximum clamping ability. Hard anodized finish prevents premature surface wear.
🧠 Why Adjustable Cam Gears Matter
Stock cam gears lock you into factory timing — great for reliability, but not ideal for tuned or modified engines. The BC8830-1 Adjustable Cam Gears let you unlock performance hidden within your 2JZ’s valve timing map.
Performance Benefits:
-
✅ Fine-tune powerband for turbo spool or high-RPM gains
-
✅ Optimize intake/exhaust overlap for forced-induction or N/A setups
-
✅ Increase horsepower and torque through advanced cam timing control
-
✅ Correct timing after head machining or aftermarket cam install
-
✅ Improve throttle response and engine balance
With just a few degrees of adjustment, you can dramatically alter your engine’s character — from street-smooth to track-ready.
