Looking them up myself, it appears this should be the part number info you should have:

Sub Model: F150
Tonnage: 1/2-ton
Location: Front
Wheel Drive: 4WD
Inches of Lift: NO LIFT


Front RS5000 High-performance Shock
SKU #:
1JA 492819
Mfr. #:
RS5233

I am wondering if they didn't send you these:


Sub Model: F150
Tonnage: 1/2-ton
Location: Front
Wheel Drive: 2WD
Inches of Lift: NO LIFT


Front RS5000 High-performance Shock
SKU #:
1JA 492821
Mfr. #:
RS5235

Other than having to do it again, they do offer a guarantee that they fit or your money back...Years ago I had to order shocks for my 75 F250 4x4 and ended up having to do them by custom order, as the ones they claimed would work had the wrong mounting... Also were too short... Aside from all that, welcome!
