ARP 2342503 Stud Kit

ARP is top shelf high grade bolts, nuts, and others high strength easterners. Their USA history is second to none. The 12 point socket fit perfect. I will never use cheap parts for items like crankcase bolts. I chased the threads to ease the installation. I used a balance beam torque wrench snug this bolt on a 2000 silverado 2500 4WD. The truck runs fine. I replaced the oil pump, hoses, water pump, front crank seal, oil pressure screen, oil pan gasket, oil pump p/u tube and added a new coolant thermostat. All this was just part of regular maintenance in light of any the oil pan gasket needing to be replaced. I had nothing better to do so I replaced a bunch of other parts.The truck will probably reach 300K miles shortly then it will time for a new vehicle. I will be sad to see my Bessy go away when she hits 300k.

worth the money

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.

One star off just because of the price. Close to 30 bucks for one bolt is pushing it in my book. But I have never had a single problem with ARP and their stuff is top quality. Install was a breeze and it even came with a small pouch of lube for the threads.

Great upgrade for any ls engines I would Highly recommend it for ANYONE that has to replace the crank bolt or hamonic balancer

holding my balancer on quite nicely

It’s a good bolt

A must have over the stock GM torque to yield bolt, especially if your installing a aftermarket damper (harmonic balancer). Just be ready to torque it to 235 ft-lbs!

washer is to big for ati dampners. you must have it turned down

best bolts in the world
