Designed to restore optimal hydraulic performance in drag-racing applications, this valve and spring kit is tailored to the instant-reaction needs of Pro Tree configurations, ensuring consistent line pressure and lightning-fast trans brake engagement. Manufactured by Coan Racing in the USA, it bolts directly into the Pro Tree valve bodies without requiring additional modifications.
