ARP Main Stud Kit for VW VR6 12V (AAA / ABV / AES) – Race-Proven USA Quality

The ARP main stud kit offers unmatched strength and security for the crankshaft in performance-built VR6 engines. Whether you're running a turbocharger, supercharger, or pushing high RPMs in motorsport – secure crankshaft alignment is critical to engine longevity.

Built for Extreme Loads

Manufactured by ARP (Automotive Racing Products, USA), these main studs are made from 8740 chromoly steel and deliver a massive 190,000 psi tensile strength. Far superior to OEM bolts, they’re trusted worldwide in professional racing engines.

Precision Fit – Maximum Reliability

Each stud is heat-treated, thread-rolled, and centerless ground to deliver consistent clamping force. This ensures crankshaft stability even under extreme boost and high-rev conditions – preventing block distortion or main bearing wear.
