Description
Aeroflow SBC 350 2-Bolt Main Stud Kit (Large Journal)
High-tensile 8740 chromoly main stud kit engineered to prevent main cap walk and fretting in Small Block Chevy 350 engines.
Overview & Performance Benefits
Engineered for high-stress street and competition builds, the Aeroflow Performance AF37-2200 Main Stud Kit provides superior clamping force over OEM cap bolts. Manufactured from aircraft-grade 8740 chromoly steel and cold-forged for high molecular integrity, these studs resist main bearing cap flexing, walking, and fretting under extreme cylinder pressure.
Using studs rather than traditional bolts yields far more accurate and consistent torque readings during bottom-end assembly by avoiding rotational friction against the engine block threads.
