Nice bolts
I was hesitant to use ARP because if I use them for one purpose I would have to commit and use them anywhere I can. The bolts looked and felt great and being able to re-use them gives me comfort. I will be replacing any bolt I can with ARP.

Great products
ARP products have replaced every nut and bolt on my build because i am a firm believer in their products. Well worth the extra money spent if you want your high HP build to hold itself together.

2001 Cobra - Clutch13
Awesome product
Great product and recieved it quick . For the price you can't beat this product. If your planning on a rebuild on a 4.6 motor then I def. recommend getting these due to not being able to get the main caps to torque to exact specs simultaneously. My stock bolts kept stretching to different specs so we put these on in a matter of minutes and got the correct torque we needed. I shop around for the best prices for everything. Everywhere else These studs were over ?300.

The quality of the bolt and super thick washer and being 12 point. Looks awesome. It looks great with a ati super damper.. would deff suggest getting this as the factory bolt isnt as strong as this one either.
