Can anyone tell me the spec. of the Stock Coil Springs on the SRT6.
The front spring has snapped on my car so it failed the MOT (I am in the UK).
I have tried to get a new spring but failed so far, Chrysler UK are trying to find out when they can get some for me.
If I can get the dimensions of the springs and the compression lbs, I have found a company that can make some for me, until then my car is off the road...

 

From the SRT page-----Engineers achieved this objective by increasing the Coupe’s spring rates to 451 pounds per inch in front and 480 pounds per inch in the rear. Roadster spring rates are 431 pounds per inch in front and 491 pounds per inch in the rear -- over 100 pounds per inch stiffer than the base Crossfire coupe and roadster. Many on here have cut the springs to lower the car---You may want to buy an used set and do this---Just a thought---Jimmy

 

just a thought mate but you could give ACD a look www.chryslerbreakers.co.uk they had a few crossfires in before christmas, not sure about srt but you might be lucky, a few members went there in october and they were very helpfull, just mention ukcrossfire club....chris

 

Thanks Chris,
I've tried them plenty for the na cars but nothing for the SRT6.

 

Thanks Jimmy,
If I can get the physical dimensions of the spring now (Height, outside diameter and gauge) I can get a new pair made, as I haven't been able to get any new or used ones in the UK.

 

Check with Needswings, he may have a lead on owners that have upgraded to aftermarket springs. You may also consider giving your non broken spring to your supplier.
BTW what is the built Month, Day, Year of your car on Label on driver's side door?

 

Thanks for the suggestion, I will try to measure my spring first. The car is locked up in a friends garage at the moment, I will get back to you with these details, when I go to it next.

 

I have found a German company, that also supply in the UK, they can cross check manufacturers and supplied me with a spring the next day for a fraction of the cost with Chrysler. if anyone needs a spring Email them at this address uksales@suplex.com.

 

http://sd.site88.net/xf/2005_crossfi...ts_catalog.pdf opps, front spring not rear Page 8 appears there aRE 3 DIFFERENT PN"S FOR SRT 6 COUPE FRONTS

check parts info, appears that all have the same part # 0510299aa FOR REAR

Page 217

 

Would it be best to replace BOTH the fronts to be certain of a MATCH?

 

The Chrysler dealer wanted £90 for 1 spring (if they can get one, I have been waiting a month for them to tell me when they can get one) suplex UK are supplying 2 springs for £76 Including next day delivery. So I am changing both....

 

I got the front spring part number from the crossfire parts list (OE 05102297AA) and Googled it, a lot of vendors showed up so I've ordered a pair for £68.50 (for the pair). Interestingly the part number refers to the springs for the SLK320 on which the crossfire is based.
I'll let you know how it goes when they arrive in the next few days.

 

I was led to believe that the CF springs were stronger than the SLK320.

 

"The Coupe’s spring rates are 451 lb./in. in the front and 480 lb./in. in the rear, while the Roadster’s are 434 lb./in. in the front and 491 lb./in. in the rear, compared to 303 lb./in. front and 337 lb./in. rear on the original Crossfire Coupe and Roadster models."

I thought the slk was higher spring rate since they where heavier.

 

I have not studied the springs in any detail but I heard they were different, the SLK being a softer ride.

 

I had to change front springs again, and I compared to SLK320 (R170) springs. All dimensions are exactly same and looks just fine under the car.
