Aeroflow Small Block Ford Windsor 289-302 2 Bolt with Girdle Main Stud Kit - AF37-2216

Aeroflow Performance main studs are designed to keep your main caps in placed and stop them walking and fretting which can lead to engine failure. These studs are preferred over bolts as they allow you to obtain more accurate torque readings.
These main studs are manufactured from aircraft quality 8740 high tensile strength chromoly steel and cold-forged to ensure molecular integrity within the stud. Meaning these studs are rated up to 190,000 psi making them stronger than Grade 8 and OEM fasteners. All kits come complete with 12-point nuts and hardened washers for an even load distribution and accurate torque readings.
