my ram assist has slowly been leaking and is getting worse and worse. looking to get a new ram. as of right now, i have a 1.5x6. PSC sells a 1.5x6, 1.75x6, and a 2x6. sometimes when i'm jammed up in the rocks, not even the ram will allow me to move. just wondering if going to a 1.75 would help any in the rocks, or does the toyota ps pump not supply enough pressure for it? also, i don't want it to be any slower in response than what the 1.5x6 has. will i benefit any going to a 1.75x6 or maybe even a 2x6 or should i stick with the 1.5x6?
