Looks like the bilstein's you found will work great. Bolt them on and move on.
This is exactly why I trust ORD as they have done the research and testing. I don't believe that they charge that much more to give you a product that they have found good results with.I would love to know what the actual valving is in the ORD shocks also. I emailed BILSTEIN a while back asking them for a suggestion on my rig. Here is my question and their response. Not trying to add confusion but rather try and come up with some answers.
Email inquiry:
I have a 1970 K5 blazer with a 4” lift kit and am looking at putting longer travel shocks on it. I have come up with a couple of options based on the amount of travel I am looking for but am trying to figure out what valving options to go with. I know you sell a kit for the 73 and up K series blazer and trucks with part numbers 24-187077 in the front and 24-187084 in the rear but there is no information on the valve rate. From the research I have done it looks like potentially 255/70 on the 24-1870077 and either 255/70 or 170/60 in the rear 24-187084. Am I on the right track or way off.
Thank you,
BILSTEIN’S Response:
Hello,
I would recommend a 360/80 for front and rear, this would be closest to the valving in the vehicle specific 4600 series part numbers 24-009232 front and 24-192941 rear.
Thanks for your inquiry
I would love to hear some more response from any one who has done the research also.
I looked up Your part numbers they sent you for the front and it came up as stock length replacement shocks. The rear came up as a lift shock though. I’m not sure they looked at you lift amount just what fit a stock truck in the front.I would love to know what the actual valving is in the ORD shocks also.

I dont want to spill the beans.What part number did they sell you? What is your application or specs?
Did I spill said beans? I don’t want to cause drama.Should I delete my post?I dont want to spill the beans.

That is an old part number which doesnt cross to my current numbers.
They are 5 dollars more to buy from ord than other retailers. Why waste the time. Just make a call and get the right stuff.

But if it isn't what you want..Because you can buy the 12” shocks for my application for $67.95 elsewhere with free shipping. (4wheelparts on eBay) but the valve rating is 255/70 on part number 33-185569 not the suggested 360/80. That’s $30 cheaper per shock.
I want to buy from ORD, they nor anyone here has made any comment as to why? Just because isnt a reason.But if it isn't what you want..
If you had something that you did the research on, would you give it away for free if it was part of your income or business? That wouldn't put food on the table..
