This a set of 2 180 KSI connecting rod bolts. These are as strong as the stock rod bolts but have the Torx Plus drive system to make them easier to install and torque. They are 7/8″ long so they can engage all of the threads in the connecting rod. They will stick out a bit on the other side but still clear the engine block on a standard stroke crankshaft. They use a T27 Torx wrench.
