Adjustable Cam Gear
(Single Row Chain)
Adjustable Cam Gears are the only way to change cam timing on 20R, 22R, 2RZ and 3RZ series Toyota motors and still be accurate. Both single and double adjustable camshaft gears are available from LC Engineering. Adjustable cam gears are generally used to correct camshaft timing after the head has been milled or when the block is decked. Cam gears are an effective way to dial-in a camshaft by advancing the cam for low-end power or retarding the cam for top-end power.
Adjustable cam gears can be used with mechanical fuel pumps by modifying the pump arm to clear the gear locking nuts and utilizing our Modified Mechanical Fuel Pump Eccentric, see Part #: 1021028. If swapping from Mechanical to an electric fuel pump you must use a distributor drive gear spacer in place of the Eccentric, see Part #: 1081025. These spacers are found on most 22RE/RET stock engines since they use electric fuel pumps.
