Seeking Gen 2 ACR facts

[sparkrn]

As a Gen 2 ACR owner I am naturally curious of what all makes my car different then the standard GTS. Below is a list of items that make up the original ACRs. If you could add to the list or correct it, please do so.
-BBS one piece wheels
-Factory K&N air filters
-smooth tubes
-5pt harness
-1999 Koni shocks, 2000-2002 Dynamic suspension shocks (both adjustable w/ supplied wrench)
-Fog lights deleted
-Radio deleted
-AC deleted
-ACR badges on both sides of hood
-ACR nameplate on counsel unless a 2002 FE car which has the FE # nameplate
-Option of Comfort group which includes Radio and AC

The next two items I am not sure about.
-stiffer springs
-10qt oil pan instead of 8.5qt.

If you can elaborate or correct this list please do.

- ACR Oil filter adapter

And yes:
1. spring rates are stiffer. On my 2000 ACR (DS shocks) the rates are: 50​​0 lbs​/​front - 1100 lbs​/​rear
2. 10 qt oil pan

How is the adaptor different and for what reason?

10 qts oil pan is not ACR specific but rather year specific. my 00GTS has it

The standard adapter by passes the oil cooler at idle to help with the AC. The ACR version doesn't have the valve and the oil has to go through the cooler.

The Koni's were on the 2000 model year until mid year. I believe it was possibly March or late Feb builds when they Dynamic shocks were used. The stiffest springs were only used on vehicles with the dynamic shocks. Also the Koni's equipped vehicles did not come with a spanner wrench. As mentioned the ten Qt. pan was a 2000 model year upgrade across the Viper line.

So your saying that the springs were stiffer with the DS shocks then the Konis? Is the 500F/1100R lb. statement seem to be correct as far as you know for the DS, and would any one know the spring rates with the Konis. I sure wish Dodge would have stayed with the Konis, I've never heard a good word on the DS shocks.

Does anyone know if the 10qt oil pan was any earlier then 2000. Apparently this is for ACR and regular GTS cars. Before the 10qt pan was it a 8qt or a 8.5qt pan.

Sparkrn, I looked but couldn't find the spring rates, spend some time on the VCA site and I'm sure you'll find the answer, or call Jon B at PartsRack.

As to the switch from Koni's, the price!! Similarly the G4 guys would rather have Moton's then KW's, and, cost is why there aren't belanger headers on the ACR-X.

Best wishes, would love to own your FE-ACR!! Mike

Thanks for the information, I bought this ACR about about 4 years ago with 172 miles on it. I think I have the only set of DS shocks that haven't leaked out yet!

[Patentlaw]

Per the shop manual, it is ok if they leak some. That is normal. People go all crazy when they see it, but they were designed that way.

I wouldn't bet that the gas charge hasn't leaked out, though. Not good if you take the car for HPDE days. Also note that it is highly recommended to change the rear springs from 1100 lbs to 800 or 850 lbs. The ride was much better after I changed mine. Bought from Jon @ partsrack.

Viper Gen 2 spring rates:

96-02 Non ACR's spring rates were 225 front and 450-500 rear
99 ACR's ACR that uses the KONI 2812 damper has 400 front, 700 rear, 2.25" ID racing springs.
00-02 ACR's use Racing Dynamic Dampers and 500 front and 1100 rear

[Kari_Lindstrom]

...some more spring rates ;):

2003-2006 SRT-10: Front: 200 lb/in, Rear: 500 lb/in
2008 SRT-10: Front: 210 lb/in, Rear: 525 lb/in
2008 ACR: Front: 514 lb/in, Rear: 1085 lb/in
Competition Coupe spring rates are 1,100 front and 1,500 rear

[RTTTTed]

The oilpan change was for the "Creampuffs" My 01 has the larger pan and my 99 has the smaller pan.

The Koni shocks were nick named "Rattlers"

The a/c and radio delete were called the "Hardcore package" and are very rare

The BBS were forged lightweight racing wheels in place of the forged stock "5 spoke" wheels. All stock wheels were forged one piece after they discontinued the welded cast aluminium wheels mid 1997.

[Bill Pemberton]

AC delete was not called a Hardcore Package, that is pertinent to the Gen IV. There were very few with the A/C deleted as noted, maybe 9-10 each year. The DS shocks were not designed to leak , they were a veritable problem from the beginning and many were replaced under warranty. Dodge switched to DS due to the constant complaining from Viper owners about the rattling noise, which was common with Koni's back then, but the guys that tracked the cars loved them -- high tech for back then. One of the reason 99 and early 2000s are sought after, they have the Konis.

I wonder if the shock change had anything to do with an agreement Dodge had with Koni/DS as the Neon ACRs ran Koni adjustables from 97-99 and also switched to DS adjustables in 2001.

[Camfab]

The 2812 Koni is a great shock that's still available from Koni, however the shocks on the ACR were specifically valved for the Viper. Numerous calls to Koni tech has yielded me zero info. on any of the shock specifics. I wanted to buy a spare new set from Koni but no one I spoke with had any tech on them and basically told me I had to source them from Dodge. If you've priced these from Dodge you'd understand why I don't want to go that route.

[46hemi]

2001 AC delete cars are the rarest with only 4 being produced that year.

[sparkrn]

IVR Shows 1999 -9 cars w/out comfort package,00=17, 01=4, 02=8. Those gotta be some misreble hot cars.

The ACR/radio delete was a weight savings. Race cars use "cool suits" and their advantage is that they don't shut off when you step on the throttle. LOL

Mine is red too, but I was wondering if the white stripes make it faster or slower?

All that extra weight from the white stripes would have to slow it down! ;)

[MalingatorGTS]

My AC doesn't work, and even with an upgraded stereo and door speakers, it's tough to hear it over the exhaust...does that count??? :stickmen_burningsti

I do need to replace the AC O-rings and recharge my AC. Other than this typical maintenance problem, the AC has always worked great on my ACR.

[blownrunner]

One thing to remember about the acr shocks is that the chrome piston is exposed and attracts dirt. The dirt gets into the oring area and causes leaks. The service manual i think states to keep this area clean. Race parts also come with higher costs and more maintenance. My acr shocks ' pistons ere really dirty in the rear and dried up oil was on the lower control arm. Since I cleaned up the shaft leaking seems to have stopped.

Plus it increases the drag quotient.

It's my experience that race type parts are made to be pounded on pretty hard but they need maintenence. They tend not to be "install and forget" type of parts. They can take more extreme force/heat/stress but they need maintained,,cleaned, even rebuilt more often. I believe due to tighter tolerances. You get better performance but less room for error, so to speak. This is obviously a generality but it makes sense with the shocks.

Also, FWIW, I don't think I have ever seen a Gen II ACR with no radio/ac in person. Seen one pop up for sale here or there, but never in person. I could see that being a real collector piece if it's real and didn't just have the radio/ac removed.

Year, asking price?

[drewsss]

It's in the classifieds. Being red, the "very fast" descriptor is debatable. :rolleyes:

Oh whatever. Be careful with that joke, it's an antique.

Hey, if it still works, go with it, right Jeff?

It does still work, I hope...:witless:
