Some are having issues with ride height in the front with these springs what is the Ford Part number for the front and rear? I want to verify that the correct springs are being bought. Do the springs have PN stamped on them anywhere, is their a way to identify them. Is there anything between a Bullitt and Gt that would cause the GT to have a higher height then a Bullitt. Thanks in advance.

 

ther are paper tags on the spring which have engeering #'s on them that I can cross-over. get me those #'s and we'll see what you got

 

Here are the two numbers on the shop invoice 1r3z-5310-ca front 1r3z-5560-aa rear. I dont have the car now so cant check the tags on springs.

 

ok, here goes. 1R3Z-5310-CA is a Bullitt front spring part #. the ID tag should be RED and have FFF on it along wth the stamping # of 1R3C-5310-CB

now on the rear spring is part # 1R3Z-5560-AA, also has a RED tag wth the ID # of RRR and its stamping # is 1R3C-5560-AA

does that help?
