Brand: Automotive Racing Products (ARP)
ARP High-Performance Series Flywheel Bolts are forged from aerospace-grade alloy steel and heat treated to 180,000 psi strength rating. The threads are rolled (not cut) after heat treating (not before). This process costs a bit more, but it results in bolts that far exceed the strength of OEM bolts.
This set includes six 7/16-20 x 1.0" bolts with 12-point heads and a packet of ARP assembly lubricant. Fits Chevrolet 90° V6 & 265-454 V8s with 2-piece rear seals and Ford 289-460 V8s.
