I said I would be in to get it in a few hours. She did have it set aside for me, but it was only half of the part I asked for. When I asked if she had the other part she said she didn't know but I could look over there. When I couldn't figure it out I said I would check what I had in my car (to see if I had the other part) and when I looked back at her she was rolling her eyes at the other employee behind the counter while saying okay.

I have a 2019 Tacoma Off Road and Carlos D. over at Go Big helped me solve suspension and tire…read morerubbing problems I started to have and was offering solutions that suits my set up and driving needs. I worked with Carlos throughout this whole process and I'm glad I did because he knows his stuff and the details when it comes to suspension systems. His customer service work ethics are 10/10. I needed a rebuild of Icon 2.5 coilovers and some new all terrain tires. After the rebuild, the shock itself started leaking and Carlos told me to bring it back asap so they can fix it at no charge and make it right. At that time I decided I needed some new tires and they set me up with the new Falken AT4s. After the installation of new tires, alignment, and rebuilt shocks, i started having tire rubbing issues from the increased tire size. Carlos offered a re-alignment to increase the caster even more from what it was originally set at to try and minimize the rubbing at no charge. The alignment was done and the rubbing came back when driving on certain roads so Carlos said to come back again. At this time, he offered to realign again at no charge, but also recommended a cab mount chop to alleviate the problem for my suspension system and tire size specifications. I decided to take his recommendation and went with the chop. I'm glad I decided to go with the chop because it made the most sense and they did a great job with the welds and paint job. I appreciate Go Big's work and shout out to Carlos for his dedication to making the job done right and offering solutions when things don't always go as planned. The solutions Carlos offered were cost efficient but also the right solutions for my driving style and set up. 10/10 customer service and 100% I'm a returning customer. Thanks Go Big!
