Customer Reviews

High quality & excellent customer service Review by Mike J New Mexico
I am 100% satisfied with my purchase of these JBA upper control arms. They installed with ease in my 1st gen Tacoma. They complimented the toytec boss coil overs that I have on my truck and look awesome. Everyone who sees my truck always notices my newly installed UCA’s. If your looking for aftermarket UCA for your Tacoma give JBA a good look when comparing you won’t have any regrets when you purchase from this company. Customer service is top self and I had one of the best experiences buying from this company. Customer service these days is lacking but not with Marlin and his company. I recived an email 3 months after my purchase to remind me to grease my UCA’s and to check in on how the product was holding up. Thank you Marlin! (Posted on 10/15/2018)
