Expand Your Driveline Upgrade Options with a Sonnax Adapter Flange Yoke

Sonnax NMRA NMCASonnax adapter flange yokes make it easy to convert a two-piece driveline to a one-piece, U-joint-style driveline - an ideal upgrade for a wide range of modified performance vehicles. New for 2021, the company's popular 3-bolt adapter flange yoke is now available with a special spacer that adds 8L90 and 10L80 transmissions to its original lineup of 6L80, 6L90, TR6060, '05“'06 Pontiac GTO and TR3160 (manual) applications. Each adapter flange yoke is precision machined from 6061-T6 aluminum for excellent fit and balance, stronger than the OE cast steel yokes and lighter in weight. Combined with Sonnax tubing and weld yokes, these unique components dramatically increase strength and durability while reducing future maintenance costs. They're the ideal choice for drivers struggling with the troublesome guibo and/or CV joint(s) in modern muscle cars or for doing drivetrain swaps and retrofits in custom street rod/hot rod applications. Available in multiple styles and bolt configurations, adapter flange yokes are the latest driveline innovation from Sonnax America's #1 source of performance aluminum driveshaft components. Learn more about the new 3-bolt adapter flange yoke kit T35-GMFD-01K and other Sonnax components at Since this is a custom part and may fit more models than noted above, contact your performance or driveshaft specialist for help speccing out a build.
