TKX for the Generations: Article by Jim Smart
Slip Yokes
In many cases, converting to a TREMEC TKX or T-56 Magnum will also warrant minor driveline modifications,
such as upgrading to our 31-spline aftermarket slip yoke.
Built to OEM standards, they accept 1330-style U-Joints and are designed to handle the torque
from one of the powerful 5 or 6-speed manual transmissions.
