Sonnax 6-bolt adapter flange yoke kit T33-ALFY-04 is an ideal upgrade for '05–'19 Ford Mustang driveshafts. Specifically designed to bolt up to 95mm bolt circle diameter pinion flanges, the Sonnax yoke allows elimination of the OE CV joint. When used with a stub and slip assembly, it makes it easy to also eliminate the rubber giubo (sometimes misspelled as guibo) or "flex" joint, converting a two-piece driveshaft into a one-piece, U-joint style driveline.

Combined with Sonnax tubing and weld yokes, this unique flange dramatically increases strength and durability while reducing future maintenance costs. This yoke is also very helpful when swapping a modern muscle car engine and transmission into an older street or hot rod, allowing the link to be made between the modern driveline and older chassis.

  • Precision-machined for excellent fit and balance
  • Helps eliminate the troublesome giubo and/or CV joint(s)
  • Ideal for chassis swaps
