2342503 Harmonic Balancer Bolt for Chevrolet Gen III/IV LS1 LS2 LS3 LS6 Small Block 4.8L / 5.3L / 5.7L / 6.0L / 6.2L Engines (Except LS7)

Used this harmonic balancer bolt on my 2000 Vette when I replaced the balancer because I read the OEM bolt is a torque to yield bolt. That means you torque it once and that’s it. New bolt isn’t ARP quality but can’t beat it for the price. 24mm 12 point socket for those of you wondering what size socket to use.

This is a great product, and the price is excellent as strong as ARP boat and half the price. Great product works well torque well and it holds great.

As another person stated, the washer won't even fit on the bolt, it stops where the threads end. Just got it today, will be sending it back tomorrow. I figured it was crap, but for the money I figured I'd check it out. Not going to trust it on a motor I just put $4k into. DO NOT BUY THIS!!!

I wasn't so sure about using something other than ARP, but I always like to try and give the new guy a shot. Well this was one of those times that it was worth every penny. It sure looks like ARP and the packaging and quality are very very good. I would use this brand again, as a matter of fact I ordered a set of their head studs as well.

worked perfectly

Willl score higher when I get it on, should say socket size in info.

Haven't ran the engine yet but the washer center hole was not big enough had to drill out other than that seems to do it's job

Easy to install, just torque to the specified spec (235 ft-lb). You’ll need a 1 1/16 12-point socket. Don’t make the same mistake I did and order a 24mm! (That is the factory hex bolt size)
