This is a brand new pair of (2) HKS Adjustable Cam Gears for Mitsubishi 4G63 Turbo Engines. Other stores show only quantity 1, however this engine requires 2 cam gears. Both the intake and exhaust cam gears for the 3sgte use the same part number as they are identical.
The angle that the stock cams are clocked to when installed at the stock location on factory cam gears not always the most effective for making power with aftermarket cams. Aftermarket cams with more aggressive lift and duration often need to be dialed in a a specific angle to optimize the powerband for your setup. Adjustable Cam Gears are important when installing cams as they allow you to dial in the cam degree for optimum performance.
