(1) *Balance Weight for SCJ or CJ428 Applications Only


*Due to the precision of the SCJ and CJ 428 we will provide you with the counter balance weight for the flexplate. However, it will come as a separate piece and will need to be balanced with your rotating assembly to ensure accuracy. This is not a capability we have in house.


Are you using a transmission that needs a shift computer? We offer package deals that include US Shift stand-alone controllers. If have a 6R80 we recommend the Quick 6 stand-alone. You will save $125 dollars off of the cost of your Speed Gems adapter kit.

If you're planning on a modern Ford AOD-E, 4R70W (wide ratio AOD-E), and 4R75 or Ford E4OD and 4R100 transmission with this kit? By adding a US Shift Quick 4 stand-alone transmission controller you will save $100 dollars off of the cost of your Speed Gems adapter kit. 

We have additional options from US Shift. Please give us a call or email us if you're not seeing what you need!
