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
  • 8HP7X Ultraflex Dodge

Sturdy, high-quality components
Color: Vivid Orange1, Size: 16pcs
Well-made reamer and plug inserter, as well as the 10 plugs, and the accessories. Even the pouch is high quality. Included instructions are very clear -- just be sure not to insert the plug with too much force, or you'll put the entire plug thru the hole. It's so much easier for a simple in-situ scooter tire puncture repair, where removing the tire can be much more time-consuming than removing a car tire. Including the high-quality little water/soap solution mister is a thoughtful feature. I highly recommend.
