Sonnax T35-ALFY-07 – 1350 Series 6-Bolt Aluminum Adapter Flange Yoke
The Sonnax T35-ALFY-07 is a high-performance aluminum adapter flange yoke designed for increased strength, durability, and reliable driveline performance in demanding applications. Manufactured from high-strength 7075-T6 aluminum, this precision-machined flange yoke provides a durable connection between compatible factory-style transmission or differential flanges and a conventional 1350 series U-joint.
Featuring a 6-bolt mounting configuration with a 94mm bolt circle diameter, this adapter is an excellent solution for converting factory two-piece driveshaft assemblies to stronger, one-piece U-joint-style driveline configurations. It allows the elimination of factory rubber flex discs (giubos) and/or CV joints in compatible applications.
Designed for high-horsepower street performance, drag racing, custom drivetrain swaps, and other demanding applications, the T35-ALFY-07 offers a lightweight, high-strength alternative to factory-style driveline connections.

Important Fitment Information
Verify transmission or differential flange bolt circle diameter, bolt hole diameter, flange outside diameter, pilot diameter, and U-joint series before ordering.
Important: This adapter features a 94mm bolt circle diameter and a male pilot configuration. Not all Dodge, Cadillac, BMW, or other listed vehicle configurations use the same flange dimensions.
On compatible Hellcat applications, this adapter mates to the transmission output flange. In other applications, it may replace a factory CV joint connection on the transmission and/or differential side.
This adapter is designed for 1350 series U-joints. A complete one-piece driveshaft conversion may require additional components, including the appropriate tubing, weld yokes, slip assembly, and U-joints.
This adapter does not fit Dodge Demon or Demon 170 applications.
Custom applications may be possible when all mounting dimensions are compatible. Always verify measurements and driveline configuration before purchasing.
