Amazing accuracy, and superb quality! I bought the EVOLT here, and it exceeded all my expectations. Highly satisfied!
The head shape has been optimized to improve operation during air intake, fuel efficiency, airtightness during compression, exhaust efficiency, and durability. It uses excellent POM material that is rich in fatigue resistance and wear-friction characteristics, and has excellent self-lubricating performance. Furthermore, by equipping a thrust bearing, which was thought to be difficult to install in that space, it eliminates twisting during spring compression and maximizes performance. This is an essential item for internal customization.
