Yes, for the same reason why they don't offer the Pro with KDSS: it's made in Japan. Bear with me.
It's made in Japan at the Tahara plant, which is one of the most automated factories in the world. The 4Runner is likely its most mature assembly line there, since the truck has been around since 2009. It's also the one with the smallest throughput (units sold). Changes in integration (yes, including adding more paint colors) disrupt the 4Runner's tightly run assembly and takt times, on an export-only vehicle that is already at the mercy of import tariffs. Just adding paint colors is probably enough to shave profit margin down to unbearable levels. The Pro is the exception, and they charge dearly for the new changes (up again by $3500 this year). By contrast, pickup production is in San Antonio with 2 shifts and in the case of the Tacoma, more demand than supply. They have no tariffs and by extension, a more comfortable profit margin.
For the same reason, they do not install Pro suspension or any other trim pieces on the 4Runner in Japan- it would disrupt a mature and optimized production process. All Pro trucks (4R, Tundra, Tacoma) start with the Off Road model and then are changed by a TRD task team AFTER the assembly is complete. In the 4Runner's case, after it arrives port-side in the US. This is justifiable for a small volume of units that command a vastly higher price, such as the Pro.
When Toyota reviewed the man-hours required for the Pro upgrade task team, they still have to make sure there is a comfortable margin. It is my assertion that the complete disassembly of the KDSS end links and extra cylinder manipulation would kill this margin. Thus, no KDSS availability on the Pro.
uke:. In addition to the black wheels, black chrome and back door handles/mirrors, they also paint the lower portion of the front/rear bumpers in black as well as the rocker panels. I had to get the pics from Toyota Canada in order to get a better look at it.
