i need to replace my worn out 5100 series bilsteins with another set. three places i contacted said the part number is changing from be-5-6681-h5 to be-5-6681-h6. but nobody could tell me if the part number change meant the shock design,etc was changing. anybody have any info?

 

found a retailer that sound the valving is changing, hence the part number change.

 

be on the look out for yellow bodied Bilsteins.. I think they are top of thier line. Also, I though Bilsteins were warrantied for life..
