Our K20/24 M-series M11 Extreme Duty main studs are made from the highest quality American steel that have gone through rigorous testing and treatment. We use a true beam design all the way through the length of the stud (it's not necked-down or undercut like others) resulting in better clamping force and torque values. "Only settle for the Best!"

The kit includes:

-M11 studs

-M11 washers

-M11 nuts
