� 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

The Prescription for Optimum Pressure

Stronger pressure regulator springs raise pressure equal amounts at idle and maximum pressure. Many aftermarket "kit" springs are a compromise, raising pressure too much at idle and not enough at maximum pressures. Larger boost valves, on the other hand, have a "progressive" effect on pressure, changing the rate of pressure increase.

The Sonnax large ratio boost valves and stronger pressure regulator springs are designed to work together. This is an ideal combination: smooth engagements and lower load on the pump at idle, but a greater increase in pressure as the transmission is worked harder.

For a more in-depth look at raising line pressure, read The Prescription for Optimum Pressure in the Sonnax online technical library at www.sonnax.com.

Description
 
Sonnax line pressure booster kit RFE-LB1 is an improved design over a simple resistor circuit. Featuring an integrated chip (IC) circuit and a stronger pressure regulator spring, this new kit delivers 10 psi increase at lower pressure range and 25 psi increase at higher pressure ranges. Only Sonnax line pressure booster kits provide progressive pressure increase which gives you smooth engagements and lower load on the pump at idle, but a greater increase in pressure as the transmission is worked harder. To find out more about how the kits work, and what results you can expect, see Achieving a Progressive Pressure Boost in RFEs.
This kit is ideal for heavy duty and modified vehicles and even stock transmissions when a little extra pressure is desired.
Achieve shorter shifts and increased torque capacity without creating low-speed harshness
Improved clutch holding capacity for increased durability
Progressive pressure increase as driving conditions become more demanding
One kit fits both gas and diesel transmission applications
