I just installed the PSC Big Bore Cylinder Assist Kit - SK291. The install of everything minus the cylinder was pretty straightforward minus the fact that PSC doesn't send any instructions - only a diagram, which if you hook up according to the diagram results in the cylinder extending when making a right hand turn. That resulted in a nice mess swapping those hoses around.
That setback is minor in comparison to the main issue I have. This kit ships with very nice quality crimped high pressure hoses for the cylinder. One end has straight fittings and the other end has 90 degree fittings. It's impossible to get the 90 degree fittings on the gear box so that means they go on the cylinder. The issue I am having is that the high stiffness of the hoses combined with 90 degree fittings is pushing the cylinder forward and the hoses into the space between the pitman arm and track bar. This will result in a pinch when making right hand turns. I ran the hoses from the gear box through the transmission cooler lines and over the track bar as this seemed the most efficient route but results in the hose pushing I just described. If I tried routing the hoses outside of the cooler lines I think I would wind up with a hose shortage at full droop and the hoses want to push themselves back into the pulleys of the engine under normal conditions.
I have tried multiple combinations of adjusting and routing these hoses and nothing seems clean and efficient. I have no idea why PSC would go with 90 degree fittings on these hoses versus a 45 degree bend. All the photos I have seen show cylinder hoses with a 45 degree bend on the passenger side and a straight fitting on the driver side. This would work. These 90 degree fittings on these very stiff hoses do no work as far as I can tell. Below are photos of my current install. I still haven't tried to road test this as I just don't like the way the hoses are routing themselves basically. Does anyone have photos of these exact hoses installed on your rig? The spiral wrap is something I added to provide protection and does not increase hose stiffness.
