Evo 123 - AEM - 4G63 Tru-Time Adjustable Cam Gear (Black)
Dial in your 4G63 cam timing
The AEM Tru-Time Adjustable Cam Gear lets you advance or retard your camshaft timing to optimize power delivery on your 7-bolt 4G63T. By moving the cam timing in precise increments, you can recover power lost to head milling, match aftermarket cams, and tune your powerband to suit your turbo setup, all without swapping camshafts. The black hard-anodized finish gives it a clean, durable look under the valve cover.

Why it matters on your Evo 1-3
The CD9A / CE9A 4G63T responds well to cam timing changes, especially once you add boost, a milled head, higher compression, or aftermarket cams. A quality adjustable cam gear gives your tuner the room to find more horsepower and torque from parts you already have, helping you optimize spool and top-end power for the way you drive your Evo.
Fitment
Mitsubishi Lancer Evolution I, II and III (CD9A / CE9A), 1992 to 1995. 7-bolt 4G63T 2.0L turbo.
