I have searched over the past few years for this, and figured I might as well try again.  Once again, I have failed.

 

YakAttack accessories are pretty much all black.  With you occasional bare aluminum parts, as well as a few orange.  With all the back accessories that you can buy, why on earth can you not get the GT175 Generation II GearTrac™ 8" gear track in black?  I'm at the point where I might take a knock off brand to get what I am after.  Currently I have the aluminum installed on my kayak, but I want black.  The aluminum clashes with the kayak colors   Sure I could paint it black, but that paint would chip or scratch off.  So that is not an option.

 

Has anyone here seen the black track?

I’m going to make a guess here, strictly a guess as I didn’t look at every pc of gear trac on their site. 
 

My guess is that trac you listed is made from Aluminum. The tracks that you see that are black, green, orange, etc. those are plastic. Either injection molded or extrusions is my guess. Either way, whatever color your raw input is will be your output. 

I guess now that you mention it....all the accessories I have and have seen,  are in black plastic. None in aluminum. I guess that does answer that. 

Have it powder coated black. Durable and looks great.
