Is there any info available on adjusting acr shocks. There is nothing in the service manual and I have searched this site and the other and can't find much. I would like to soften up the settings if possible. I even bought the tool but don't know where to start. Here is a pic of one of my fronts.

I have a copy of the ACR shock guide. I got it off the Viper club website in January 05. I can e-mail (or fax)it to you tommorrow if you want me to. I will try and scan it into the computer and print photos of it tonight but I have not had any success recently in getting my photos to show up on this website. Let me know. :laugh:

they have 2 different ACR shocks, yours are the koni "rattlers" they call them that because they rattle, but its normal.

Do a seach on here for KONI ACR shocks, and I think you will find plenty of information on them. They came on 1999 to 2000.5 ACRs.

You would think there would be info here, but I have searched and there is nothing I can find on adjusting them.

It's funny I've had two of these cars with no rattle what so ever. I too have the guide if he doesn't come through. What ever you do, make sure you clean that dirty shock completely spotless before you do anything! You will destroy the threads on the shock housing. Also do not force the rebound adjusters. Clean and lube if necessary.

I would like to thank Ninjaviper for refaxing me the info twice today, since my fax machine ran out of ink in the middle of his transmission and I had to run to staples to get some ink. In the mean time, from studying his papers, I have located the info online in a "scoobies" gallery here-
ACR Shock Info

Thanks

lol, hate to call you both morons.. but you received a manual for the Dynamic Suspension shocks, NOT the Koni's that are on your car. Had you wanted the manual to a set of shocks you dont own, I could have easily sent you a copy of mine (2002 ACR).

Good luck, try again, you need the 1999-2000.5 manual.

If the info looks like what you are referencing in "scoobies" gallery,it does NOT pertain to your shocks. Your car is equipped with Koni shocks.

Jcoopacr2000, yes the shocks are rebuildable. You should have them rebuilt immediately. I believe Dan Craigin told me they should be rebuilt every 16,000 miles. Failure to take care of your problem now may result in complete shock replacement. Unless $4,000 a shock is no problem for you! I believe Koni has two factory locations where they can take care of that for you. Go to the Koni website for further details. Better yet if you have the Mopar extended warranty, take it in. I have an issue with my front right shock leaking, and I do have the warranty.

Yea Guys, you are right. I thought maybe Dynamic Suspension made the Koni shocks. Anyhow I still appreciate Ninjaviper trying to help, and Camfab- I got your fax today with the Koni info, thank you very much. :headbang:

$4,000 a shock? Is that 100% accurate? That's insane. :eek:

The Koni shocks can be rebuilt by either:
http://www.koni-na.com/
http://www.truechoice.com/

If I'm not mistaken, the Dynamic brand is not rebuildable. If a Koni shock can't be rebuilt, replacement is around $900 from either Koni or True Choice.

Shocks are NOT covered under "extended" warranty, but it may be covered under the factory warranty.

Synfull - adjusting is done by rotating the adjustment discs, located in the window of the top eye (top portion of the shocks). You only need a steel pin, a small drill bit works fine. The upper disc is for Bump (compression), and the lower disc is for rebound (extension) adjustment. Rotate the discs according to the markings on the top eye. It is marked with plus and minus signs. You should hear it click when you're making the adjustments (never use excessive force). The discs need to be rotated 180 degrees to go from minimum to maximum adjustment (there's a total of 7-8 adjustments I believe).

This should be real interesting, I was told the shocks are covered under my extended warranty by DC Performance. I will find out for sure tomorrow. Additionally I just reviewed my extended warranty paperwork,there is no shock listing in their exclusions sheet. It's nice to know that those shocks are attainable through Koni directly because they sure aren't $900 at the dealer. My question would be if they are valved exactly as they are when purchased from Dodge.

Not quite true on a couple of counts. First, the Dynamic Suspension shocks are rebuildable. The Newman-Haas race team uses their shocks and you can contact them at Dynamic Suspension Contacts . The guys in IL can rebuild them for usually less than $200/shock.

On my 01 ACR 3 out of 4 Dynamic Shocks leaked at one point or another and all three were replaced under my extended warranty.

Hope this helps.

The Konis are simple to adjust. The bump and rebound adjusters are stacked discs, located beneath the upper shock bolt, with holes in them to insert a small drift punch. One adjuster is bump, the other is rebound. (I don't know which is which)

The window in the top spring retainer will undoubtedly be full of sand and road grime. First, _Put On Safety Glasses_. Next, blow them out with compressed air. Then, spray with brake cleaner and follow a dose of WD-40. Insert the punch (or an allen wrench) and sweep them back and forth to free them up. Be sure to count how many clicks it takes to get to the limit of 8 clicks for each adjuster. Keep a little notebook in your console so you remember what the shocks are set at, then experiment a click or two either way on each adjuster and make notes about how your handling changes.

The spring seat adjusters should also be brushed, blown and sprayed clean before changing anything. Put a reference mark on the shock and adjuster so you know where you started and ended, then write that info in your little notebook too.

Wow.. so much wrong information in 1 post (adjustment info is prob right).

1.Dynamic is rebuildable, and if you go to their website, they will give you the only US location allowed to service them.
2.The shocks ARE covered in extended warranty, since I am already at 58k miles and I had one changed last month, I have BEEN in my extended Max Care warranty for a while now.

So when should they be rebuilt? Someone mentioned in here that every 16,000 miles they should be rebuilt.

I'm calling BS on this one too. I have gone as much as about 50k on a single dynamic shock and about 20-30k on others and track my car a good number of times at VIR. Fortunetly for me, the leak often, so I get them replaced under warranty. But there was NO disserable difference from the shock they replaced with 50k miles on it, with a brand new one. So if they leak replace them, rebuilding at 16k... nah... unless you have money to blow...

thank you so much for giving the correct information on this deal. i looked up the link you povided and called them on the phone. they said that they can rebuild dynamic suspensions shox for $200 each. the shox is built in a way thay is not readily serviceable so what they do is install a schrader valve and now the shock can be rebuilt to stock spec or whatever spec you desire. all this for only $200. this is way cheaper than $4,000 a shock. F-that. so with that said i know where i will be sending my front two shocks that are leaking.

Jon, the info regarding rebuilding them was per Dan Craigin. If you think about it, you've had three of four shocks go bad. Rebuilding may just be precautinary to prevent shock destruction after a seal failure. Many guys here may not service their cars, thus not noting heavy fluid loss. Guys without the extended warranty should be listening. Anyway thanks for confirming extended warranty validity, I'm calling today.

If anyone wants a copy of the KONI user's manual, I will try to post it to my gallery later today.

Sure, just saying, save the cash, let the warranty work for you. If you have only THOUGHT about a max care warranty, I urge you to commit now. It alone will save you a ton of money, on shocks alone.

Its nice to see those nice new gold shocks and springs every time I look under my car, and know that my paultry $1800 extended warranty has paid for them, a new diff, a water pump, new 1/2 shafts, wheel hub, stereo headunit, power steering pump (soon to be installed), new A/C compressor (soon to be installed), a few interior pieces too, among other things I am forgetting....

Get an extended MaxCare warranty.. you'll be "shocked" if you dont ;-)

Dodge should have gone with Penske, but Dynamic was making strong concessions to them with the French-run GTS-R program. A front-line racecar will probably rebuild and revalve shocks at least twice per race meeting, so they never run long enough to start leaking. I've had Penskes on my car for about 4 years and never had an oil leak or nitrogen pressure loss. The quality of the Dynamic units on the ACR has been abysmal. Plus, they're oversprung and/or under-damped.

...but they look good... :rolleyes:
