VALVE TRAIN COMPONENTS are packages designed for different stages of tuning!

PHASE 1
PHASE 2
Reinforced Valve Springs are required for high engine speeds and high loads to allow the valves to follow the camshaft profile and ensures adhering of valves to valve seats. For that reason, these products are designed to suit the high loads that are present in tuned engines. So Titanium is used to help reduce mass in the Valve Spring Retainers. This helps prevent abnormal valve movement such as jumping and bouncing. In addition, our Valve Guides are made from Phosphor Bronze Alloy this helps with improved wear resistance and heat dissipation. The valves are then effectively frees the excessive heat from the valves and transfers the heat into the cylinder head.

In addition to the PHASE 1 setup, the Phase 2 is designed for the next level. This stage will help flow more air-fuel mixture into the combustion chamber with the aid of the 1mm oversized exhaust valves which are included in the set. In addition to increased diameter of valves, the thinner diameter waist shaped valve stems helps with allowing more flow on both the intake and the exhaust sides. This increase in valve diameter brings the valves closer to each other and easily builds up heat which causes cracks in valve seat surroundings. Greater wear resistant and heat dissipation methods are then addressed with the use of Bery Rings, which are made of Beryllium Copper Alloy. These are used to increase sealing properties and heat dissipation which prevents compression loss and cracks by increasing durability.
