E4OD (89-E93) Driver Adjustable Pressure Riser
* The Driver Adjustable PressureRiser is a control module that is mounted inside the vehicle allowing the driver to switch “on the fly” from no modification to Standard, Heavy Duty, or High Performance. * The Driver Adjustable PressureRiser is ideal for any vehicle that is used partially for towing. It allows the driver to give the transmission the extra holding power needed when towing and adjust the comfort level to the driver’s preference when not towing. * Great for the “weekend warrior” who wants the maximum holding power for his offroad adventures.
