If I am blacking out the engine on my Slim, do I need this part as well as Rocker Box Cover (part #17620-99)?

Hello KCGrant, Yes you will need 2 bases and 2 rocker box covers for your model and year in order to complete you look. Before you purchase the part please verify fitment for your model and year. Good luck with your project.

Wrinkle or Texture black

I have a 2015 Street Bob and the stock rocker box covers are the same black as the crank case and i believe that is "Texture Black" not "Wrinkle" like the primary, transmission and Cam cover. If i'm correct "Texture Black" is almost like a flat black wrinkle and "Wrinkle Black" is like gloss wrinkle correct? So my question is are these rocker lowers "Wrinkle" or "Texture Black" to match the uppers?
Asked by: justinryan
Hi Justinryan, The Rocker Box Lower Housings are a "Texture" black to match the uppers. Thank you for your question.

Do these come as a pair or separate?

Asked by: dubbers
Hi dubbers, Sorry it's not so straight forward. These are sold seperately (one unit per package), two being required. Hope this helps!
