I am trying to determine if the ABS bikes have a different lower fork section than the non-ABS bikes?

I am getting ready to purchase some powder coated lowers. I checked the H-D site and they only listed one part number and it did no specify ABS or not.

If all the ABS and non-ABS are the same, how far back in years are the forks interchangeable?

 

My 09 parts book shows 46496-00A and 46498-00A for the sliders, so you're good. No reference to ABS on the page

 

Yep, they're the same.
