Product Description
SET OF 10
These main bearing cap bolts are a higher bolt class (grade) than the regular L and NAPS-Z bolts, and can replace the OE bolts
The higher strength bolts can be torqued to a higher than stock torque value (60 lb/ft), but if you want to run the higher torque, you must align-bore the main bores at the higher torque
If you torque to the higher value without doing this, you will oval the bearing bores and lock up the crank
The Nissan Motorsports catalog reads as follows:
H/D MAIN CAP BOLT
These heavy duty bolts are constructed from a higher grade material,
which allows a 50% increase (to 60 lb/ft) in the torque setting
Heavy duty bolts are marked with a small "12"
