CPP 500 or Ecklers Saginaw 605 Power Steering Kit

I have a 64 ss with factory power steering and I've searched up several kits one CCP and uses a 500 Series gear,
another kit from Ecklers uses a 605 gear box and seperately another offers a drag link with pitmanarm & idler arm for use with 605 gear box.
Has anyone had experience with either?

The CPP 500 is a reworked 605 Delphi (formerly called Saginaw) power steering gear box. The rework was done to allow the "500" box to be bolted onto a Tri-Five Chevy directly without an adapter or mounting bracket. It is called a "500" because Delphi sued CPP over a trademark infringement on their 600 series of gear boxes. Even though Delphi also makes a number of 500 series manual steering gear boxes there was enough difference that Delphi's lawyers left CPP alone with only a name change.


The CPP500 is manufactured but only partially machined in China. There have been a lot of complaints about the poor machine work quality and reliability issues if you research the issue on line.

used a 'kit' fromEckler's that uses the Delphi Borgeson 600 box. Yes, it steersquicker and feels more precise than the original 4 1/2 turn lock tolock original box. There are a couple of things that Iencountered though that you need to consider.
1. The stop to stop was reducedgreatly (less that 3 turns), however the turning radius increasedbecause the stops in the box limit the travel of the pitman arm toosoon ....at least in this application.
2. The box itself mounts higher onthe frame and this results in the pitman arm being about an inchhigher than originally. The result is a greater angle from driver'sside the drag link to tie rod than the passenger side resulting in aslight change in steering geometry on the driver's side compared tothe passenger side.
Does it matter? Yes. Thisincrease in drag link - tie rod angle will mean the to getproper front-end alignment, the driver's side tie rod will have to beadjusted significantly longer than the passenger side furtheraltering left to right steering geometry. This WILL result in someoccasional bump-steer and handling will be affected to some degree. How bad? That depends on what you find 'acceptable'.
There really is nothing wrong withthe original steering other than it being soooo s-l-o-w, but....there is at least one company that will rebuild your steering boxwith 'quicker' gears. "REDHEAD steering gears" (www.sreetinggears.net) will rebuild your Saginaw box with new gears that will quicken your steering down to as much as 2 1/2 turns lock to lock ...AND the cost is less than $400 plus the core. (I just spoke with them.) This is a MUCH easier and less expensive way to go. ...a simple remove and replace job. ....NO 'rigged' 'conversion' non-stock parts.

Tie rod raised like that will introduce bump steer as well.

Call Dan at Lares. They rebuild any steering gear part for any vehicle in-house. If you are wanting to eliminate the slave cylinder system, I believe they have a set-up for that too for less than the aftermarket vendors.

Contact at Lares Corporation

Personally, I won't buy anything from cpp again. One conversion of their chinese crap is all I need.

No the steering gear box is self contained (ram is inside the box).

Not sure what you are asking. The original poster wanted to loose the power assist ram, the hoses and the extra long steering gear box and replace it with a more modern one that offers road feel for one, as well as faster turns with variable ratio steering not found on the 1953-'64 power assist steering.

Are you attempting to repair your existing power assist that uses a hydraulic slave ram attached to the frame of the car to steer or are you going to rip the stock steering out and replace with aftermarket parts? If you need original steering parts they are offered as reproductions on Corvette sites as the Corvette and the full size used the same steering in 1964.

You are going to need all of the parts that are applicable to a 1958-1964 B-body (Impala) as your car has unique suspension components that dose not play nice with most aftermarket upgrades.

Lack of the ability to fully adjust your steering geometry is just one issue reported by others on this board who have used a mixture of stock and aftermarket parts.

You need to find a copy of the instruction sheet and order any missing parts from the vendor that put the kit together (such as tubular A-arms, long ball joint studs, modified tie rod ends, or idler arms that might be required).
