Works like a champ
Snapped the OEMs hex stud right off becuase the middle bolt that ties the top of the spring to the tensioner body was designed to lock the spring in place when the bolt was tightened ! This "feature" defeated the ability to adjust the tensioner simply by loosening only the top bolt. This updated design allows the spring to move even when the middle and lower bolts are tightened down. The top bolt must be loosened first, though, but that makes much sense than the original design.

Amazing product
The tensioner smoothly fit in as eliminated the perturbing squeaking noise. All of the other tensioners elsewhere were too pricey while this one was a perfect deal.

Customer Q&A
Ask a question to 1A Auto customers who purchased the product
What brand is this? Warranty? Actual customer results? I just bought another off brand that started rattling in four whole days.
Scott L January 4, 2018
We have a few different aftermarket companies who are based in either China or Taiwan build these parts specifically for us, as our 1A Auto house brand. They are manufactured to the same OEM specifications as the original part that came with your vehicle. If you have any further questions, please dont hesitate to ask.

Dont know the brand but I bought one for my sons Scion TC last year (8 months ago) and it is working fine. He drives back and forth from Houston to Austin all the time for college. It was a chore installing it but once in no problems.

This model is unbranded from an anonymous Chinese manufacturer sold by many vendors.There is only a single manufacturer for this item. Some vendors sell this on 3bay for 25 bucks or less. I installed this item on my RAV4 2.4L 6 months ago with excellent results. Warranty ?! HAH HAH !

Sorry but I dont remember the brand. It comes with the standard limited lifetime warranty and to be honest I have never had to cash in on a warranty for any of the parts that I have ordered from 1A Auto over the last several years. I installed the tensioner pulley in March of 2017 on my 2005 Toyota Solara, after breaking the bottom off the original unit. It is not only still working great but it is working in the -20 plus temperatures that the car has been subjected to lately. The belt runs smooth without any vibration. I wouldnt hesitate to recommend the part to anyone.
