OEM lower pressure plate modded to accept 6 bolts to better distribute clutch pressures during install and use. This will greatly assist during installation of heavy duty springs and will prevent breakage due to lack of support. This mod will require a 6 hole spring lifter plate such as kevtek, drow, or chimera. Swapping the lower pressure plate does require a special socket for removing the oil spinner and clutch assembly. Only 3 bolts are included, you will need to reuse the 3 stock bolts! I recommend no more than 8nm of torque with a 1/4” torque wrench or the mounting pegs may strip out.
