AEM Tru-Time Cam Gears Mitsubishi Eclipse GST GSX 4G63T 89-99
AEM TRU-TIME Adjustable Cam Gears increase horsepower and torque without having to change the camshaft(s) and are must-have items for engines that are milled, forced induction, high compression and/or utilizing aftermarket competition cams. Our gears enable users to match cam timing with their vehicle's tuning state by advancing or retarding the cam profile in one-degree increments via true laser-etched markings. Precision-cut gear teeth ensure no premature wearing of the belt surface and AEM's anodizing on the gear teeth is lab-test proven as the hardest anodizing process on the market.
AEM TRU-TIME Adjustable Cam Gears are available in a multi-spoke, five-bolt design for most vehicles and our classic full-faced, three-bolt design for select applications. Five-bolt cam gears have an ?8??? in the suffix (23-8XX), and three-bolt cam gears have a ?6??? in the suffix (23-6XX).
Legal in California only for racing vehicles which may never be used upon a highway.

About Manufacturer: AEM Electronics
When racers and enthusiasts buy AEM performance parts, they are getting the finest engineering, highest quality and best value our industry has to offer. Look no further than our products for proof. AEM created the first stand-alone programmable engine management system that uses a factory wiring harness, and was the first to introduce a gauge with a built-in wideband UEGO controller and gauge readout in one unit! More recent innovations include our Water/Methanol Injection Systems, which provide the ultimate combination of performance, quality and value for gas and diesel race vehicles, a complete line of digital and analog display gauges, and the X-WiFi module, which allows users to view critical exhaust data wirelessly on virtually any WiFi enabled device. In addition, the recent release of AEM’s Series 2 EMS with AEMTuner interface software represents a major evolution in features and ease of use from the original.
