Show original supplier description
The Tomei Adjustable Cam Gear is crafted from Duralumin, offering both lightweight construction and exceptional strength, finished with a vibrant red anodizing. This sliding-type cam gear allows for precise timing adjustments using its integrated degree markings, enabling tuners to optimize the engine's power band for enhanced performance. Engineered for the 4G63 engine, these adjustable cam gears are compatible with Mitsubishi Evolution models IV, V, VI, VII, VIII, and IX. However, a crucial note for Evo IX owners: this gear does not replace the MIVEC intake cam gear. For the MIVEC Evo IX, only a single Tomei gear can be used on the exhaust cam, as the factory intake cam gear must be retained. This ensures proper functionality of the variable valve timing system. These cam gears are available for purchase individually or as a pair, providing flexibility based on your specific tuning needs. Their durable construction and adjustable nature make them a valuable upgrade for performance-oriented builds seeking to fine-tune engine timing.
