I asked around in my Jeep group for recommended places for re-gearing, and was told about Premiere West Gears. For starters, the recommendation came from a highly reliable and knowledgeable guy in my Jeep group, but I still did my research and even called another shop. Another shop, that quite frankly, I would have trusted too, but their price was 37% higher than Premiere West. After reading all the reviews and also taking into account that being in business, you won't be able to please 100% of the clients, 100% of the time, but if you're able to please a very high percentage, then to me, that's the real deal. As these guys were working on my re-gear (Jeep XJ, 4.10 to 4.56), I was able to step into the garage and watch, and ask a few questions. They pointed out to me that the copper air line for my front locker was pinched. I examined it up close and decided that it needed to be replaced. Fortunately, Miguel said that there was enough time to get the part before his guys were done with the job. I thought, if I could pull this off by getting the part, I won't have to pay labor again to open up the differential to replace the copper line. I called on my little brother and he picked up the part at a local 4WD shop in Riverside, and delivered it within an hour. That is true customer service, not being nickeled and dimed for a little extra work. I had the Jeep out the very next day to Dishpan Springs and it performed flawlessly with the new Revolution gear set. Fyi these gears don't require the typical 500 mile break in period. Thank you Miguel and your shop personnel for being so accommodating and reliable. I will use these guys again if the need arises.
