Quick Overview



Sonnax hydraulic line pressure booster kits contain stronger pressure regulator springs and
large ratio boost valves designed to work together to provide progressive pressure increases as
driving conditions become more demanding.
Our pressure regulator springs are approximately 10% stronger than OE and more conservative
in impact than other aftermarket “kit” springs. 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.
• Kit fits all 6L45–6L90 applications
• Achieve shorter shifts and increased torque capacity without creating low-speed harshness
• Improved band and clutch holding capacity for increased durability
• Progressive pressure increase as driving conditions become more demanding
• All the benefits of increased line pressure without overloading the pump at idle
• Simple and affordable drop-in solution with no special tools or reaming required
