  • TITANIUM VALVE RETAINER
  • TITANIUM VALVE RETAINER

TITANIUM VALVE RETAINER

It is required for tuned engine to make a movement part light. The role of a retainer is a stopper for valve springs, retainer needs to be extremely strong and lightweight for reliability and engine response. The JUN Titanium Valve Retainer has been developed with emphasis on both strength and weight in mind. Furthermore, the Type2 valve retainer is performing the special surface treatment. And compared with Type1 (conventional article), wear resistance of it improved very much.

Type 1 JPY71,280yen

Type 2 JPY93,960yen

  • SIDE SILLS FOAMING URETHANE REINFORCEMENT KIT

SIDE SILLS FOAMING URETHANE KIT

This new reinforcement method makes high rigidity feel simply, so that it reverses old common sense. The car which performed urethane body reinforcement can feel the difference, when it get in and departs, you feel a motion of a car. The car which has constructed the roll cage etc. is still more effective. Although there is a difference in the ratio of an effect also by the new car or the old vehicle, rigidity is raised certainly.
