Upgraded Power Steering Pump (1 Viewer)

[MK80]

I had a local shop install a Trail Gear 2”x8” HD hydro ram assist and now I need to upgrade my power steering pump. It’s pretty tough to turn the steering wheel/front tires at low RPMs.

The closest thing I could find was when Slee did a SAS on a 100 series LC and they used an 80 series steering box with a PSC high pressure/volume pump. I called Slee and the guy who did the work no longer works there so they couldn’t give me any concrete details. So I then called PSC and they didn’t have much for me to go on either.

So I am turning to the Mud for help. I need a way to turn my system into a high pressure system.

Never seen one - 100 has a different engine than an 80 and therefore a different pump. 80 pump is gear driven so not as simple to swap in a different unit.

Yeah...80 box not 80 pump. PSC belt driven pump mounted to a 100 series V8.

Ahh I misunderstood.

Well I still need help regardless.

Almost everyone with hydro assist on an 80 is using a 1.5” for this exact reason

I hate to do this to you but...

Trail Gear told me to get the 2” when I called asking them about it. Damn.

It’s also trail gear

Didn't that Russian guy with the airbagged 80 recently post about modifying the power steering pump? I can't even find his original build thread at the moment.

A 2" ram is stupidly oversized. Go smaller

In the pump there is a restrictor -- right below the hose connection that i drilled out --

I bought the 1.5” to swap it out.
