ARP 2342503 Stud Kit

very good quality

I heard about people using the o.e. bolt and they come off because of the high torque. I just put the bolt in gave it one good tighten and 4 months now and still holding

Always great products from ARP! Used on a LQ9

ARP look no further. Fit perfectly on my LS3. Note it’s a 12 point use a 27mm 12 point impact socket.

Top notch quality, easy to install,never needed their warranty.

Its pricey.

Used this bolt on a 2012 GMC Sierra with a Non-AFM 6.2 liter. The vibration dampener installation kit I rented wasnt the correct size and this bolt got the the dampener installed! Hand turned it until I had 6 threads in the crank then drove it in with the impact gun...flawless ( pulled bolt out after installing and threads were still perfect) . Wouldnt buy any other fastener for this application.

Used this on my LS3 with LSA supercharger. I used an ATI super Damper, pinned the crank and added this ARP bolts for peace of mind. Torqued to 200ft/lbs per instructions.

So far it’s been good bought it 3 months ago and haven’t had any issues with it.
