InlinePRO M-series M11 Extreme Duty Head Studs Accord Civic Si RSX TSX K20A2 K20A3 K20Z1 K20Z3 K24A

Our K20/24 M-series M11 Extreme Duty head studs are made from the highest quality American steel that have gone through rigorous testing and treatment. These are not prone to hydrogen embrittlement like the L19/H11 material and it can be handled without worrying about failures. 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
