RT-A11-PR - 15B
LML 2011-2015
Pricing: $75.95


For the every day truck. Kit sets minimum pressure and boosted pressure to levels that are a match for stock 400HP and up to 800HP levels adjustable within the kit.

Its not uncommon for customers to say their engine runs better after installing this kit. This is because de-fueling under torque management will be eliminated. The trans will have enough holding power to allow full fuel delivery.


  • Improved Pressure Regulator Valve Function
  • Improved Torque Converter Clutch Function
  • Increased Torque and Horsepower Capability

This kit also includes a Higher Calibration E Shift Spring (Part# RT-A-ES). Sticking E shift valves can cause codes P1711 or P0872.
