Perfect fit!!!
Was really worried about the quality of this product since at all the auto parts stores I checked, this part was $400. But it looks well made, looks the same as the original and fit perfect on my 99 lexus gs300. Thanks!!!

Perfect Price and Fit
I have a 1999 Lexus GS300 and called the Lexus Dealership for a price. They wanted almost $500 for this item. I did a google search and found this website. I'm sure glad that I did. I ordered online, added overnight shipping and received it the next day. What great service! I installed it myself with absolutely no problems and two weeks later. My car runs smooth. I just ordered all of my ball joints for my vehicle without paying an arm and a leg. Luckily I know how install these items on my car saving me tons of labor costs. I highly recommend 1A Auto parts.

Purchased for my 01 Lexus GS300
Purchased for my 01 lexus gs300.... the car was making a loud very concerning screech when the AC would be turned on, when reversing, or when making sharp turns. Took it to three mechanics who all said harmonic balancer/crankshaft/pulley. I purchased this part due to prior satisfied reviews and took it too a mechanic who made the replacement for $260 overall cost of repair was $311 , thankfully... if I would of gotten part from lexus my total repair costs would of been around $600 . Thank you so much to 1A auto. My vehicles loud screeching noise is gone and I can now use the AC which is nice! The car is no longer shakky or making any noises whatsoever. That embarrassing noise is gone for good! ??????????

Perfect quality.
Came in on time and does it job exactly right. Definitely worth buying it here instead of paying $400+ at an auto store. It was difficult putting it on my IS300 (2JZ-GE), but only because it was pointed towards the front so I had to remove the radiator fans, radiator, air condenser, and grill before getting to my old harmonic balancer. I was satisfied with the performance after.
