GT1R Crank Bolt

No. This is a massive M18 bolt designed specifically for the aftermarket GT1R Bryant crankshaft. It is too large to fit the threads of a factory R35 crank.

Due to its size and the clamping force required, this bolt must be torqued to 350 ft-lb. This is significantly higher than factory specs to ensure the damper stays secure.

The larger M18 diameter offers vastly superior tensile strength and clamping load capacity, which is essential for preventing the harmonic damper from shearing off in 2000+ HP engines.

Achieving 350 ft-lb of torque requires a heavy-duty torque wrench and a mechanism to lock the flywheel or crankshaft securely so the engine does not rotate during tightening.

This bolt is specifically sourced for the thread pitch and snout depth of the GT1R Bryant crank. Using it on other cranks (like Sonny Bryant or Winberg) requires verification of thread size and depth.
