Pro Comp ES9000 Shock Information and Specs

[Walking Eagle]

If shocks are not supposed to take the weight of the vehicle, they'd be designed the exact same way as steering dampeners. Steering dampeners dampen movement, but have no preference for being open or closed. Shocks want to be fully extended, some more than others.

Non-gas charged shocks don't want to be fully extended - they are just like steering dampers.

Gas charged shocks want to fully extend - and there is some force there as you hold them at ride height (and why they can be a pain to install) - and obviouslly that force is going to effect ride height - to some degree, though it's usually very little - and extra 50lbf at each corner doesn't do much to 6,000 lbs

So I e-mailed Pro Comp today and got the following info. They responded to my e-mail in less than an hour! (Sent at 11:37, responded by 12:12!)

These are the recommended shocks by Pro Comp. The first would be a set for a stock height vehicle, the second would be a set for a J spring(ish) lifted vehicle with 315's (these might be slightly long and need the bump stops spaced down a bit, it's your job to check that! ). All of these should be a straight bolt in option.

Guh.

What is the 927xxx application for?

The shocks I ordered, the fronts are for older F150's (pre-'78?), the rears appear to be generic.

[edit] The front 927530 is over a full inch longer fully extended, the rear about 1/4". They both have slimmer bodies than what I ordered. I am curious about valving, but expect their valving to be pretty generic acorss the board.[/edit]

The set of non-gas charged shocks that were in my truck originally want to be fully extended. They are easy to compress, about on par with the OME's. They extend slower than the OME's do, and both of those combined are nothing compared to the Pro Comp's.

I've read several accounts of people installing non-gas charged shocks as a steering dampener....and then wondering why the vehicle wants to pull left/right.

To be true it has a lot to do with the shock design, but I haven't (personally) seen a shock that acts like a steering dampener. I suppose you could get adjustable shocks and set the preload to 0 if you wanted that.

As far as the 50 lbf at each corner....I guarantee you that the Pro Comp's were much more than 50. The easiest way to compress them was by leaning my full body weight on them. They were not fun to put on the truck, and I was sore for days afterwards.

Even still, as you said, it's not much of an effect. How much? Apparently a half inch. ;p

Valving should be the same. Pro Comp uses a variable valving as opposed to a fixed valving, and it's the same across the board for all of a series of shocks.

These are simply Pro Comp's recommended shocks for those applications. Meaning that they should bolt straight in. The shocks you ordered may or may not work better for you, and you may need to swap bushings or do a little fab work for it to all come together.

I simply wanted to offer up some shocks that should bolt straight in for those who wanted an option without any fab work, swapping bushings, etc.

As far as the shock body size goes, there's advantages and disadvantages to both.

The 2.36" body shock will hold more fluid than the 2" body shock for the same length. The more fluid you have, the more heat it can take. But it's also a larger shock which means perhaps harder to fit.

A longer 2" shock compared to a shorter 2.36" shock will probably have about the same amount of fluid in it, so if you're getting a longer shock it's probably not a big deal.

Now if you're looking at something like a 1.5" body shock...that might be a problem.

I found the 927XXX pro comps in Calgary. They were ordered out of the US by one of our brothers there who totaled his rig and never got them in. After a quick conference with Ebag, I bought them and will be putting them in my LX.

I will take pics and post what I end up with. I also grabbed some front bump stops from a 60 series diesel at the scrap yard today .. they bolt right in! Just need to get some extensions fabbed up. Can't wait .. this looks like a great way for those of us on a budget to get decent shock for out OME springs. Thanks again Ebag!

Specifically you have the shocks recommended by Pro Comp.

Guess we'll see how good of a recommendation those are!

I put my Pro Comp shocks on today, initial impressions are favorable but I'll wait a few weeks and a couple of wheeling trips to come to any conclusions.

Ebag these shocks are much easier to compress by hand than the stock replacement Bilsteins!

Just a data point: 4WPW has Energy Suspension hourglass shock bushings P/N9.8108G 3/4" ID that are a direct fit for this rear shock on the 80 and cost $5.

Jeeez. Do you need a jack to put them on then?

Sweet. Added to the first post.

Got a chance to do some trails yesterday with these shocks on and I am quite pleased. Ebag I didn't get a chance to really stretch them out and check lengths etc as the trails were very very slick. But the ride is very good, on the gravelly roads leading to the trailheads and on the trails. At slow trail speeds, the suspension was very supple and compliant, a lot less pitching than w/ the Bilsteins, yet no slamming or violent pitching.

Going back out next weekend and will have a better chance to work them and cycle the suspension, checking for restrictions etc., and generally getting a better feel for how they perform.

I rode along. The combo with the FOR and those shocks was Luxury. I was very impressed with the ride. I will be there to check out the total flex next week. I'm expecting things will go well.

What, no pics?

I have my Pro Comps in as well. I agree with the above statements. Very smooth on gravel and NO jarring in changing terrain, even at decent speeds. I haven't done any measurements either, but will do and post soon. I have also done some decent corning at speed and there is no sway or lean to speak of. For half the money of OME .. In this novice's opinion, a great shock that performs very well.

My rear shock set CAME with the correct bushings for the rear in the box! Just popped out what they came with and stuck the other set in.

Another big thanks to Gabe for doing the ground work and getting us into these shocks!

 

[little_joe]

Very happy with the shocks!

I am very happy with these shocks! I realize they are not for everyone, but in combination with the FOR springs, the ride is right where I want it onroad and offroad.

Got another full day on the trails yesterday and initial impressions hold - excellent stability yet supple. The suspension feels so much better and it cycles effortlessly. I just wish the front end on the 80's had more travel. It does appear I'll have to drop the bumpstops a bit as even w/ the 295's I got some rubbing in the rear wheelwell/frame.

I get a slight bit of progressive sway onroad when turning, likely more due to no swaybars front or rear. However, it is nowhere near as pronounced as the full-height FOR's w/ Frankie's shocks and swaybars on each end; and it feels more stable than OME 2.5" w/ OME shocks.

 

[Ebag333]

The orientation of the lower mount does concern me a tad but only time will tell. Let us know in a few months time frame, how the shocks are doing. Good bang for the buck factor!

Cheers.

Been a few months, and was actually under the truck yesterday fixing my exhaust leak. Checked the shock mounts, still looks like new.

 

[Kaoscruizer]

rear shock blown!

One of my rear shocks has a leak, fluid and dirt all over it. Guess I got a bad one cause all I have done is some bush roads with my rig since the new shocks were put in. Gotta order a new one today .. still lovin' them!

 

[Kaoscruizer]

WOW! .. customer service at it's best!

Just to keep you Pro Comp users updated, I emailed Pro Comp this morning and explained my situation. I told them that I bought the shocks new in box from a fellow MUD member and that I only had them on for 2 months before one rear shock blew. I asked if they could find a way to warrantee the shock, even though I DIDN'T have the invoice. Here was the response about 45 minutes later:


Good morning. We have 2 ways to do the warranty on the shock. First you can purchase a new one from us and we will bill you and ups the new shock to you. When you have swapped the shock you can return it to us for credit. The second way you can do the warranty is to send us the shock back first and when we receive the shock, we will send you a replacement at no charge. Please let me know which way you would like to proceed and we will get you handled.

Thanks for supporting Pro Comp products.

The bushings used. They are different sizes for different sized bolts.

 

[ravencr]

Gotcha...anyone know the bottom rears should be for our rigs?

I don't think that Pro Comp has a 14" travel shock with the correct bushing already there.

Check the first post for a bushing you can buy and press in.

 

[ravencr]

k, thanks. I missed that...my long post scanning ability is slacking...

Anyone have a long term update of these shocks quality? Get what you pay for, or still surprised they're working so well? How's the compression dampening in comparison to rebound dampening?
