Quick ratio steering question

[Corts60]

Hey guys,

I'm getting ready to tear the front end of my '78 down and rebuild all the steering and suspension components. While I'm there, I was thinking of replacing my power steering box with a quick ratio one from classic industries P/N P27512.

Does anyone have any opinions or thoughts about if this is a good idea for a street truck or a better vendor to go through?

Thanks in advance!

I had sourced a Flaming River one for my Silverado SS a few years back. Talk with the techs there and they can even customize one for your intent (street, auto-x, 4 wheeling, etc). If I remember right, it was somewhere around $500-$600 for the custom ratio I wanted. A lot more than the one you posted about from CI. I wonder what the differences are for the '77-'79 vs other years though.

Flare fittings vs metric o-ring fittings

I definitely am not looking to spend that kind of money. I am just wanting a good box that will help snug up the steering

Is it the lines only that are different, or are the pumps also different?

There's a guy in Springfield, MO that can do whatever you want to your existing box--around $200. Power Steering Specialties. Great guy and work.

The mounting is different. Ours mount outside the framerail, most all others mount inside. Ours are 808's all the 12.7 boxes are 800's so the inner parts wont interchange either. Lee will make a 12.7 808 but wants about $800.

The fittings on the box are different. The fitting on the steering pump is different as well but it can be swapped for either style easily. The lines are different as well between o-ring and flared end

OK, so does anybody see a problem with making the ratio tighter? Would it be better to drive or worse?

Depends if your stuck behind a smart car in the city or driving the auto bahn.
There's a local company in my state called redhead steering that can adjust steering feel in the steering box and you can also shim the power steering pump to give a little less pressure and drill the output to give more flow. This will help feels as well
