Rear Spring Conversion on Ebay

[jus2rel]

Is this the proper setup to convert the rear to coils and remove the air suspension? If so, why is it so cheap? Isn't the normal price around $200 or so?

What is the difference between using these or the Moog springs others have used?

That is quite cheap. I bought my springs from the same company (except form their actual website) over a year ago and did the conversion, never looked back.

Well, I went ahead and ordered a set. With FL sales tax it only cost me $66 total.

Comparing the Ebay listing to their actual website, the model number is the same as the "regular" spring conversion that normally sells for $179. So that is over $110 discount in price. They also carry a "Heavy Duty" spring conversion on the website but I don't see any hauling or towing in my future.

Well, apparently the seller updated the price, so now it is listed for $99. Thats still $80 cheaper than ordering direct through the website.

Guess I got a good deal due to someones mistake
