ACDelco 19300488 Harmonic Balancer

Perfect fit for my 2007 GMC Sierra 4.8

Installed and works perfect. I only use OE parts for critical engine parts like this. Here's a tip for removing the old balancer: remove the old bolt, grind down the diameter of the flange on the bolt head until it is smaller than the inside diameter of the crank pulley, thread the old bolt back into the crank and tighten snugly, then you can use a 2 or 3 jaw puller to remove the old pulley without the puller damaging the crank threads.

Perfect replacement on my 2006 Chevrolet Avalanche with a 5.3L

Works as it should. No wobbling.

Good quality good value

It’s Genuine GM at a reasonable price. It fits and performs the same as the one it replaced, without the grove mine had worn over 318,000 miles. Would definitely purchase again.

I needed a truck pulley on my LS3 for the type of accessory drive I’m using. This pulley fits and is the right spacing, but it does wobble a little, which is common on some of these.

Part was a simple swap onto my 6.0. It looks great and seems to work as it should. I bought to replace a worn out factory unit that was separating and rusty.

Very good quality product and fairly priced. Exactly as advertised and fit perfectly.

Great product, AC Delco on Amazon makes life a million times easier

direct replacement

Fit perfectly as described

Looked good, but after the time and expense of installing this, it's right back to square one. Do not recommend.
