Modified VTC Cam Gear for Honda K-Series Engines

Are you looking to unlock maximum performance and tune your high-revving K-series engine with aggressive aftermarket camshafts? The Modified RBB VTC Cam Gear is an essential upgrade for any serious K20 or K24 build, providing the precise control needed to prevent piston-to-valve contact at high advance angles.

What is the purpose of the Modified VTC Cam Gear?

The Modified VTC Cam Gear is designed to mechanically limit the Variable Timing Control (VTC) advance to a specific, safer angle (30, 35, 40, or 45 degrees). This is crucial for performance engines running high-lift, high-duration aftermarket camshafts which require less advance than the stock 50-degree OEM gear to prevent engine damage.
