I replaced the factory struts because I changed rims/ tires and needed wheel well clearance. Changing them provided 2 inches I needed. I may have the struts backwards(L/R). They were Identical in vertical size. Coil count was lower. Ive read about the upper mount cup being an issue.

 

can you provide more information?
when I did my struts, there wasnt a left and a right. They were both the same.
If your mount is on correctly, you should be able to rotate the entire strut assembly untill it fits.

 

it doesnt matter if it's left or right. they both should fit interchangeably.

 

the regular coil suspension is same on both sides, but different front to rear.

i believe the air suspension units are corner specific though.

 

Can somebody verify this for the air suspension? I have seen a bunch of maybes but no certainty. I am looking at a used air shock locally on Craig's and he doesn't know which side it came from, he is stating it can be used for either. Anybody?
