Ok,

Here is the Ford Spring Charts For the Mustangs NON SHELBY only. First off I got these Direct From Ford this is Not Normally Available to Dealers. Ford Has a Real Hit and Miss Listing For Springs as they do Not Specifically List Springs by Application. They Simply List Coupe or Vert and Spring Code by Number and Color. These Two Charts Show Front Springs and Specs #5310 and Rear Springs and Specs #5560. I have Gotten a Lot of Requests for BULLITT Springs Because people Like the Ride Height. It is Possable that your Stang May Have All or 2 Of the Bullitt Springs already on your Car Depending on How it is Optioned. To Check Look for the Tag as Shown on the Spring Charts. Front Will Be Orange ID# Sgf Rear will Be Light Blue ID# SAR. Of Particular Interest is the Column CHECK LOAD. The Lower the Number the Softer the Spring and The Opposite The Higher the Number the Stiffer and or Taller the Ride Height. Also Note on the Rear 5560 The Wire Diameter. The 11.9 is Coupe the 11.5 Vert. As Far as the Bullitt Struts they were Only Used on the Bullitts so for the Ride you Would Need to Purchase the Bullitt Struts.

 

Updated. Front Spring Color is Orange ID#sgf

 

the chart is somewhat hard to read / even when enlarged .....

but we do appreciate you posting it.

its the first solid info on Ford Springs that I've seen posted anywhere.

so, how do you interpret the 'Rate' column?
