Steering box question - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Do they make different ratios, or are they all the same. Meaning if I bought a new one from a parts store would my truck still steer the same as it does now? I am talking about power boxes by the way.

You have to pay some pretty big bucks from what I understand to get a faster ratio.
The later truck...80-something went to a variable ratio...but then you'll have hose fitting issues.

I'm not really wanting a different ratio box, I was just wondering if they came from factory with different ratios, like say for instance if a truck came with a big block, and one with a small block would the boxes still be the same? I just didn't want to get a new box and it steer harder than the one that is on the truck now!

all ps boxes installed for these trucks are the same regardless of engine/drivetrain combo.

There is a place that can modify your original steeering box to quick ratio.
They also will rebuld your original unit.

Thanks guys!!!

My old box is good other than the lower shaft where the pitman arm hooks up. The splines on the box are worn due to P/O running a used pitman arm on it, sooo it wore the splines on the shaft. I got a new pitman arm and put it on and it helped the problem a little for a while until the splines on the pitman arm wore down, so now it's like it was white line to yellow line drifting to and fro!!!
