7/29/2026 Update - RAM 1350 is out of stock - ETA 5 weeks

These two flanges adapt the common 6-Bolt output flange found on many Dodge Charger and Challenger 8HP70 and 8HP90 transmissions to common 1310 or 1350 U-Joints. This is the first step to making a new custom driveshaft, or modifying your current shaft, to work with your new 8HP swap. 

Versions: 

1350: Billet aluminum. Super strong, but more expensive. The ultimate choice. We use these on our race cars, and have never had a failure or weird vibration. 

1310: Cast steel. Budget friendly. Uses smaller 1310 U-Joint that can save space for some applications. 

RAM 1350: Bolts direct to 2wd RAM output flange.
