For those of you purchased from me, thank you. When you do, I supply a diagram showing with ports are pressure and return.
If you did not purchase from me, Summit cannot give you the same advice that I can.
This box operates on much high pressures which sometimes cause stiff steering at low speeds. To remedy, I sell a specific pump with a higher relief pressure.
I understand 800 is a lot of $. However, it's a one time upgrade for positive on center steering. Rebuilt oe boxes cannot offer the precision feel and faster ratio of the modern box. You really can't compare the 2.
