Regeared Stock 16 Taco TRD 4x4 to 4:88 + rear diff locker: Found this place on craigslist and wanted to know if they were legit. So far, all the customers that I met have told me how much the workers knew their stuff and how affordable it is. I checked out other reputable shops and price cannot be beat!!! I just realized its family operated! Awesome! I spoke with Carlos whom is the manager. He always picks up when I call!! Excellent customer service. First time around I was reluctant to have my differential lockers done as I kept researching on the pros and cons of it. Came to check out the place. Carlos was kind enough to take his own time (after hrs) to educate me on the ARB lockers and re-gearing if I wanted to lift and bigger tires. If it were not for his time to explain to me how important it was to regear, I would have ended up down the line paying labor twice for doing regearing separately. Carlos is the man. When it was the day for the service, I met a guy who had a tricked out wrangler and told me how he drove all the way from downtown LA to come to this place because of how affordable it is. The mechanic told me it would have been around 4 hrs. Hiccup in the vendor brought incorrect gear size to the front diff which led to total of 7 hr job. Not Premier’s fault at all. I saw how they work. Miguel is the man for the Job! Highly recommend it. Take note, if you are a DIY kind of guy (if you can DIY fluid changes...) this is the place. (Installed air compressor and air line my self for the locker) Let Premier do the heavy lift and technical stuff for you. Keeps costs down! Love it!! Would totally come back for future technical/heavy upgrades!! (Suspension/lifts) in the future!
