Poorly labeled description

screw head is not the same size as OEM. I will not buy any other outlet just to use this product. This must be clearly stated in the product description. I returned the item and bought the bolt from a Chevy dealer for $12. Wasted time with that.

Pros
  • replacement parts
Cons
  • I vaguely remember

Quality clasp 36mm

This is ARP, the quality is as expected. I'm just writing this review to let people know that after my purchase in November 2020 they are now shipping an updated part number that includes a 36mm 12pt head, exactly the same as the factory bolt.

Pros
  • Country of origin: USA
Cons
  • No instructions

Not the same as OEM

Head diameter is smaller than OEM. There is no washing machine included as before. Called ARP and didn't get a satisfactory answer as to why the head has gotten smaller and whether I can use the original disc or should I buy an ARP disc. They didn't call me back with an answer as to whether a smaller diameter head would affect the clamping force of the bolt.

Pros
  • Package Weight: 0.53lb
Cons
  • Hard to tell
