Got my 2015 sahara lifted today. Had a great experience. Staff was friendly. Big thanks to John. He was very knowledgeable in walking me through everything. I called a few different times before my appointment and he was very helpful. I would highly recommend them. Thanks John and Transonic Customs team.

Last year I purchased some wheels and tires from them back when they were in Montclair. Some of the wheels started flaking. When I came into their new shop they were very welcoming. I told them my issue and they were very quickly to help me out. The vendor that made the wheels were being a little difficult, but Transonic smoothed it out to where I didn’t have to worry about it. They gave me Awesome customer service! I am now a customer for life!

I had received a lift kit for my 2013 Jeep JKU for Christmas. Floyd was great! He was friendly and professional and wanted my business. He gave me the best price in town for installation. Other shops in the area treated me like they were doing me a favor and quoted higher prices. The job was done quick and clean. They even boxed up my take-​off parts and put them in the back without asking. I definitely recommend giving him a call when you need work done for your Jeep or Truck! I will be going back for future upgrades!

Want to give a big applause to the technicians/​staff that worked on my 2012 jeep jk. Well organized, clean, and professional environment. I had many options to choose for my installment, but TRANSONIC CUSTOMS hands down was the best one.

Great installation, great people, and great service after the sale. I was having trouble with my satellite antenna and they made the 2+ hour drive to my place to fix it. Then they helped me reconfigure some settings on my Alpine while they were there. I will use these guys again.

Friendly employees that provide great customer work here. I brought in my 2014 Jeep rubicon to see what they had for the vehicle. They had a great selection of items for the jeep. I purchased a lift, wheels, tires, headlights, front bumper, rear tire carrier, and a minor stereo upgrade. I could not be happier with the service and the prices. I recommend this establishment if you have a jeep or any other car for that matter.

Hawthorne, CA
Did not have a good experience here. Called about wheels they had for sale was told they were available. I told them I’d be there with in 2 hours because i lived 2 hours away and was told to come. About an hour in a half in to it i get a text telling they sold them. When I called to talk to them and explain that I was on my way like we agreed I was told «he had cash in hand and it didn’t matter I couldn’t wait for you because it was money in front of me. «
Yes never got to do business with them but would never go back and would not recommend this place to anyone. They are only worried about money and then selves. They have no consideration for other or potential customers.

Great experience with transonic. Worked with Junior and the owner. Extremely trustworthy and fair pricing for work done on my truck. Had a volant cool air intake done on my 2014 toyota tacoma. Only took them 45 minutes to install and now my truck sounds and runs even better with the intake. Thanks for the work transonic and I’ll be back for future work. Highly reccommended!
