No, those are the higher pressure PR valves I said to avoid. The 2nd one is just an oversized version, notice the part number ending O/S?
The one I meant is this;
It's to raise the pressure by way of the boost valve circuit. That is a better way to do it, but it's not compatible with their older higher pressure PR kits, which come in the ZIP kit. They sell a simple quality replacement PR valve, that's the one to get to use with the above LB1 boost kit. Be sure you choose the parts for your model 4R, pre-98 or 98 up models.
