Hi, I have a 2005 f150 4.6V8 RWD with 119.000 miles. Its an XL "Workhorse" model. The VIN is 1FTRX12W45FB53348. I ordered a set of KYB SR4078 complete strut replacements however KYB says these struts will not fit a heavy duty suspension. I'm not the original owner of the truck and when I looked up the original sticker info for my truck it said it has Heavy Duty front and rear shocks. Will these KYB replacements I ordered fit? There's not a lot of info out there on the XL/Wokhorse model. The original sticker says it has the "workhorse" package (whatever that is??). It's a very basic model truck, so I can't figure out why it would have a heavy duty suspension. Thanks in advance for the help.

 

Here is a link to FordETIS it gives you an AS SHIPPED list of equipment installed on your truck after you enter your VIN.

I noticed it lists DUAL H/D front shocks, so perhaps what you've ordered won't fit. A call to the dealership parts counter to get some more info might yield a part number you can use to get an interchangeable part number
