Large ratio boost valves provide higher pressure incrementally and when it is needed the most. The combination of these springs and valves in a Sonnax kit gives you the best of both worlds: a modest pressure increase at the low end, with a high-end pressure that is equal to or greater than that of other aftermarket “kit” springs.Kits available for either early (long) or late (short) style boost valvesAchieve shorter shifts and increased torque capacity without creating low-speed harshnessImproved band and clutch holding capacity for increased durabilityProgressive pressure increase as driving conditions become more demandingAll the benefits of increased line pressure without overloading the pump at idleSimple and affordable drop-in solution with no special tools or reaming required.  Parts ship daily from our distribution center.FREE SHIPPING on US Orders GOT QUESTIONS on your specific Year/Make/Model?
