Other key parts which are different between the two bumper types include :My original SLK 350 front bumper cover cracked and for around the same price I can buy the 55 AMG bumper cover(which looks better imo) but is it a straight swap ? Or will some work need to be done to get it to fit? I have a 2006 SLK 350 w sport package
A post-facelift (non AMG) bumper fits perfectly on a pre-facelift (non AMG) R171 - see my posting/photos above.It will fit provided the AMG you source is from the same "era" (in your case pre-facelift). Also, your car needs to have the Sport Package already - which you say yours has - otherwise you need a lot more stuff such as the grille inserts and fog lights. But for a Sport Pack car it should be a straight swap.
I'm basing this mostly on the thread by Wolfman (CLICKY!) who did this and ended up having to buy a lot of bits. There is also another guy in that thread who did it and they also said it ended up setting them back over $3K to complete the process properly.A post-facelift (non AMG) bumper fits perfectly on a pre-facelift (non AMG) R171 - see my posting/photos above.
I would be interested to know why there is an issue in fitting, say, a post-facelift AMG bumper to a pre-facelift SLK350? I'm not aware of any differences in the mounting points etc.
Likewise, to my knowledge, the "Sports Package" brings differences in spring height, strut model and torsion bar diameter. What does "Sports Package" bring in terms of differences in bumper mounting?
I've disassembled the front end of all three of my SLKs (two have Sports Package) more than a few times, researched parts ad nauseum, swapped parts etc., updated models etc., and I'm not aware that pre and post facelift have different mountings, or that Sports Package has any impact.
But I'm still learning. :wink:
