LS Harmonic Balancer Installation Tool Crank Pulley Install Tool 551141 Compatible with GM 1997-UP V8 LS1 LS2 LS3 LS4 LSX LSA LS6 LQ4 LQ9 with Thrust Bearing & Wrench Flats

$65 -$100 dollars to maybe rent a kit from auto part store.. only to get home and realize it doesn't work for your car!!!! Happened 3 times before I found this tool. 2007 gm sierra classic v vin 4.8L. Super simple use. 1 minute after opening box the harmonic balancer was re installed with no fuss. Great price, great quality, perfect fit, and I didn't have to argue with the high schoolers at parts house.

Works great with some high pressure grease, but didn't come with any instructions. Easy enough to figure out. It is one time use on the thrust bearing, maybe that should earn it a 4 star but it's cheap enough to replace the thrust bearing only when needed. Possibly operator error because I used a cheater bar and put some weight on it to make sure the pully was completely set. 5 stars either way and makes install super easy and tool removal is even easier! Threads fit 2011 silverado 2500HD 6.0 perfectly

Worked as advertised. I have used it multiple times. It works great.

Great tool at a good price.

Works on an ls1/ls6 as should, but don't expect to get more than one use out of the bearings. It comes with two, but I've done two installs and both broke. Go out and buy 6 more washers so you can get a wrench on there without the main nut being inside of the balancer. Thread the tool as far into the crank as you can, then hold the end with a small wrench (13mm if I remember), and use a 24mm to push the balancer on. If you use a socket and turn the main nut, you will be turning the entire tool, forcing it further against inside of the crank.

This Harmonic Balencer Installation Tool , made installing the harmonic balencer an easy job. A must have tool if you have install the Harmonic Balencer. I'm very happy and pleased with this tool.

Awesome super easy tool to use. Do not risk stripping the threads in your crankshaft, buy this type of tool, but for your specific application. This one I used on a 2002 Chevy Suburban 2 WD 5.3l Vortec. Easy peezy nice and easy!

Great tool , arrived fast and worked perfect. Lubed the outer bore and anti seize inner bore on the balancer and lightly lubed tool threads. Installed tool finger tight , snugged with a 12mm backed off a hair and walked the nut down with a 24mm while holding the tool stud with the 12mm. Walked in no issues, tool felt smooth and sturdy.

fast delivery works fantastic

Broke inside my crank while installing the pulley. I checked the force required after extracting it with a torque wrench and it broke while tightening at only 90lbsft. Avoid wasting all of your afternoon with this. Wrote a message to the seller and never heard back.
