I could tell it wasn't made by the original designer since they took the logo off inside the head and the blue used was lighter, but it still looks terrific.
Chris L.
Part was ok but required some modification to make it work
Eric H.
Easy to install, look great, and so much more stable than the original stacks on the figure! Totally worthwhile upgrade!
Tobiáš Č.
Incredibly disappointed. The tolerances are not even close to working, even after excessive sanding down it's still like a solid 1-1.5mm bigger than it has to be, damaged my figure when trying to loosen the tolerances to make this work, the thing itself also broke apart very quickly and 2 of the joints look like they are even missing a pin??? Can't even return my figure to it's original state due to the piece that was being replaced breaking due to how fragile & thin it is when removing the pin. I had high hopes for this and they certainly did not live up to the expectations.

The prices were great and the product was amazing and makes the figures look great

As always the shopping experience at TFSafari was top notch. This upgrade kit completely remedies the OEM smokestacks issue with a much, much better set. I highly recommend these, your SS86 Optimus will thank you.

Product is as advertised and looks so much better then the original plastic ones that broke on me, I highly recommend getting this if you have a 86 ss prime
Anthony Z.
Nice pieces to fill in the gaps.
Bobby L.
Nice upgrade for Prime here, less swollen than the stock head to give OP a certain amount of gravitas that he was missing.
andy t.
it is amazing i can't believe how easy it was to install and replace. Now he looks complete 10/10 would by another upgrade kit again

Removing pin was tricky but installing part was easy.

Gap fillers make a huge difference a few had to have glue applied but not a big deal. All three purchases were a great improvement to this Prime.
Garth R.
Color matches well, fit perfectly, does not hinder transformation, and fills that annoying gap nicely, well made!
Bobby L.
Grest puece that solves a glaring problem with the original piece
Bobby L.
Great set makes a big difference to the look of the toy
Jinwoo K.
Looks great. Easy to install.
Yong K.
A badass looking head for prime! It gives him a more manga/Japanese media representation look to him which totally holds its own next to the other options already available.
Recommended especially with TF Safari’s great service!
Anthony G.
It completely fixed the issues that came with the original smoke stacks and the upgrade kit looks so much better on 86 prime
Jon R.
Came on time and well packaged! Parts fit perfectly and zero complaints!
MOSES L.
The color match is spot on it anddoes look better than most upgrade hit head kits out there.
Mr. o.
