"They told me they had the grill that I wanted for my F-150 in stock I show up and they said that they don't have it. That i needs to wait about week. I drove all the way from Palmdale. Waste of time waste of gas. Thanks smh."

"This shop has everything for your Truck LED LITE BULBS Very bright they install very friendly workers recommend this place to all Truck owners"

"I bought some head lights and bumper lights for my Chevy s10 light duty truck. All bad the owner saw me putting them on and they wouldn’t go in, they gave me some clips bro my old ones didn’t use clips, he should have offered to return them for another set….long story short one flew off while on a long distance trip….if it doesn’t fit they have to replace them them being a distributor Amazon would have been better thanks a lot Alex one star for ordering a faulty product and offering clips and wires to try to hold them in place"

"I bought a chase light bar from these guys at the Sand Sports Swap Meet. Before running the wires I decided to check the functions using my battery charger for a power source and could not make it function properly. Turns out my charger was not putting out enough voltage to operate the strobe functions. In the mean time they took the time to hook it up and run it through the functions for me. They are very friendly and helpful and I would definitely use them again."

"This company stold $3600. from us. They claimed to be ordering led lights and never produced them and then said china wont give the money back so the owner mark refuses to give us our money back... also found out that they peddle knock offs and sales damaged products... BE CAREFUL WHEN DEALING WITH THESE THIEVES!!! YOU HAVE BEEN WARNED!!!!"
