Is there a way of making the powersteering on a third Gen less sensitive?

When I used a GM pump and Mustang rack on a hot rod project, I got the same results - too sensitive.

I solved the problem with a kit, something like this:

Here is another alternative:

Went and saw a powersteering specialist and had a talk to them, they recommended getting the steering box rebuilt with more modern internals to give the steering for feel. He recons those kits you mentioned are no good for what I'm trying to fix and will eventually damage the steering box because all they do is starve the box with less fluid. Your application was different to mine.

I would like to know also. The ps in my 72 is super sensitive. There is no feel for the road at all.
My 72 is super easy to steer. Seems easier than my last 71 but it could just be me. I also have 4" front runners on it so that may be why it steers so effortlessly. I put it sideways that way I have more feeling for the road.:D

Take the pressure valve assembly off of a 85 and up monte carlo ss or simular trans -am or z/28 and that should do it. Basicaly all it is, is a slightly smaller diameter hole in the valve.

Not to overlook the obvious, this can also be caused by incorrect frontend geometry/alignment. Too little caster and not enough toe can cause sensitive steering.

Let's look at the information we have. Everything on your car is stock factory and in good condition. Obviously NOT ALL cars like yours is having the sensitive issues, or GM would have done something way back when to correct it. So if the frontend is in good condition and "your" car is too sensitive, I'm guessing alignment may be a big help. Go to someone very experienced in frontends. He hopefully will listen to your issues and "adjust" accordingly and not just say your car is in spec and leave it at that.

Before I'd do the restrictor valve for something should not need one, I would have the frontend checked out by a good frontend man and then see what you have. And only then if necessary, look at other items for correction.

Good luck.

More toe in, a smaller steering wheel diameter and a Lee 12 to 1 steering box have all worked well for me....

When I get my car aligned, I have him set the toe to close to 0, once home, I adjust the tie rod sleeve a 1/4 turn at a time till I get the feel I like...

Well also lack of feel was always a issue with the older p/s systems as they were all over boosted,but...If it feels twitchy provided all the suspension is in good working order,too much toe out will cause that. Too little caster makes it feel real easy to turn but also makes it have a tendency not to hold its line aka wander or pull. Ive seen with radial tires novas like more positive caster than the fact specs. Remember these cars were setup to run with bias ply tires wich had more rolling resistance ect. I used to set them up with about a 1/8" toe in about 2 1/2 to 3 1/2 deg of positive caster with maybe a half degree less on the drivers side to compensate for road crown. Never had any complaints and the cars always felt more stable and had better feed back.

I had the same problem.Called a company inquiring about their steering products.Told them my problem of sensitive steering. I was told to increase the caster because of going from a bias ply tires to radial tires required more caster. Told me to save my money and do this.

That's exactly how I have my 64 Pontiac set up. It made a world of difference!

I'm not sure what your pump looks like but if you use the flow control valve that's the same as 2nd gen you can add washers to reduce pressure. Look at the end to the right. There are 3 washers under the hex fitting that has the small screen. There are 2 washers next to the valve and they are about a
64th thick. Each washer reduces the pressure a little more. This valve is set for a 66. The washers may be a little tuff to find. Good luck.
