Where to buy the factory timing belt kit?

I see these kits on eBay, but that always makes me nervous. Is there a trusted vendor that sells the full factory kit (belt, pulleys, water pump, tensioner, gaskets, etc.?

Thanks!

 

RockAuto or Summit Racing.

 

I see these Aisin parts kits, but are we sure that Aisin is OEM? I will pay an additional few hundred for the peace of mind.

 

Aisin is OEM.

 

X2 on the Aisin from Rockauto. It’s the one. Be sure to get the full kit with the tensioners included. Grab a serpentine belt while you’re in there.

 

Buy a new thermostat too. Every Toyota/Lexus V8 engine I've worked on has warmed up way faster and ran cooler with a new thermostat. You need to remove it anyway when doing the timing belt job.

Aisin is OEM for that as well.

 

From the factory, where else man?

Summit is free shipping over $101 right now if I recall. They are always within a buck or two of rockAuto, and often cheaper than legit sellers on scAmazon (the cheaper sellers usually aren’t legit, and even for legit sellers you have no guarantee you’ll get genuine product)
