Are all (truck) shocks the same?

So, I'm working on installing a 3" lift on my CJ, and I'm going to need to pick up longer shocks on a budget.

Older Ford f250 shocks look to be about the right length, but are they going to be too stiff for the lighter CJ7?

Part of me assumes heavier vehicle = stiffer shocks, but I can't really find anything to confirm that.

For example, Advance carries "Monroe Gas-Matic Truck Shocks" for both a CJ7 and an f250, and doesn't say anything about one or the other being stiffer.

Gas charged shocks are stiffer. It will take everything you have to compress it, and then it will open back up again. Way too stiff for a CJ IMHO.

I've been running Doetsch Tech DT3000 shocks on mine for a few years and really like them. Hard to beat the $40 price, no matter what length you get.

Never seen them before but they do sound pretty well received.

I know I shouldn't cheap out too much. $40 is probably a pretty good compromise

The valving is different in various shock applications. Yes, the F250 will have differently valved shocks and I'm guessing different sizes, lengths, and eye ends. This is why there are thousands of different shocks out there.

I really hope that quality control has improved or at Doetsch as I ordered a set years ago and one was very different than the other 3. Customer service and trying to get a replacement was a horrible and drawn out experience with the one rep I was going through....When I finally just got a refund, They said that person was no longer there. I would be willing to try them again.

I would remove your current shocks and fully stuff and drop the axles and record the measurements from eye to eye studs. Then use this chart to determine which ones you need. Don't let a generic sales page pick your part number for you.

Well, I ended up with the Monroes after all...
I thought I was going to be able to use my old shocks for a little while, but they turned out to be too short even for on road driving.

So between needing shocks right away, and the $60 they want for shipping on the Doetsch shock, I just decided to cheap out at Advance.

I can post the part numbers I ended up with if anybody is interested, but I just looked through all the Monroe LTs until i found the right length.
They actually feel quite a bit softer than the Superlifts I had, and it came to $68 with tax for all 4. So I'm happy enough for now.

Somewhere much later down the line I might upgrade to OME or Bilstein.

There's really no need to go to high dollar shocks with leaf springs. The shocks are there to control rebound and as you found the $68 Monroes do the job.

Sometime this week I'll take it back on a dirt road where I'll really see how these handle.
Theres a nice wide, but extremely washboarded road near here thats great for testing out suspensions....

After a ride in to work on them though, I'm really happy I saved the $160

BTW, I forgot to mention the Monroes were made in the USA.

As silly cheap as they are, I'd have to put money on them being Chinese. Definitely a nice surprise.
