This transmission crossmember kit fits both our 8HP and DCT rear transmisssion mounts, and are now avaliable for purchase separatley.

 

Both the rear mount and crossmember offers great flexibility with the slotted holes, and can be used with many different adapter plates on the market. 

CNC machined out of billet aluminium and anodized. 
Comes with needed installation hardware.

 

Note:

You need to weld in thread bosses (or nuts) to fit this crossmember to the oem tunnel rails as the stock GT86 crossmember location is not suitable. We reccommend to weld in additional 1,5mm  reinforcement plates around the new threads.


Please note that all of our crossmembers are specifically designed for installation exclusively with either one of our 8HP Ultraflex mounts or DCT mounts. They are not compatible with OEM transmission mounts. If you do not have a Ultraflex mount we higly recomend getting one for a straight bolt on experience.

We cannot confirm or deny compatibility of our transmission crossmembers with products from other vendors, as fitment may vary depending on their design and specifications. For the best results and guaranteed fitment, we highly recommend using an HPR rear transmission mount, which ensures that the crossmember will align and perform as intended. 

Ultraflex mount compability:

  • 8HP Ultraflex N57/N63
  • 8HP Ultraflex B57
  • 8HP Ultraflex BMW 45/50/51
  • 8HP90 Ultraflex Dodge

great product and leaves a great shine. The Poli Glow doesn't go as far as the video states and it depends on condition of RV, boat...This is a great product but takes more to get a great shine!!

poli glow shine
its works great .when applying more coats the shinier it gets i used on several old boats because the florida sun bakes the jell coat right off and no wax made can withstand salty seas , so why not ,, when you apply use the mit and don't gob it on .. nice and easy and recoat in five minutes when you get to about five coats you will be amazed.looks like new .. just a tip also after about a year or so and you want to re apply,, go to your local hardware store and get a gallon of high strength or non diluted floor stripper and put in spray bottle and use to remove old poli-glow also great for cleaning stubborn stains [ i use full strength ] just spray on and brush with a scrub brush and rinse ..and let dry and re apply ,, its also works on car faded bumpers ,, also never use harsh cleaners it will cause streaking the best thing i have found for cleaning the boat after poli glow was put on is car wash from auto store with wax or not it seems not to hurt the shine . it reminds me of mop an glow,,.

Poli Glow used on bottom portion of the picture
Just put it on 21 foot RV, was impressed with the shine. Key is to make sure the applicator is moist. I periodically dampen with water. Realizing it wasn't going to revive the stickers. Question is How long it will last? What will it look like after it rains? Pictures attached, bottom portion was done with poli glow on June 7,2026 and I have just under a half of bottle left. Maybe I will update once it rains or how long the shine last.
