At performance gear they are professional with outstanding service professional personnel over the top mechanics great customer service was outstanding I recommend performance gear for any of your transfer case transmission standard transmission differential service in the area of Southern California....

He saved me from having to buy a whole new axle housing. His craftsmanship is of the highest quality. I highly recommend.

Good quality work at a fair price. Had gearing 1 air locker and a limited slip installed. Works great. Make an appointment.

I was overcharged 500.00 when I picked up my rear-end. I played like I dont know what the parts costed and he said it was for parts when the price if the parts is what the whole job costs. On top of that job took way too long I do not recommend this business and its sad because I was referred.

Took my 99 Mustang GT for a gear and pinion upgrade ended up changing axles and different the owner gave me a good price for the work than any other shop took 1day to do the work very happy with the installation I would recommend this shop they have reasonably price

I recently purchased a 1930 Dodge coupe and brought it to Tom for a differential service and limited-slip upgrade. Super impressed with the honest feedback, responsiveness, and fair prices. Tom is great at managing customers expectations. Do not hesitate to bring your car or differential here!!

Tom is very knowledgeable and did a great job swapping 3.73 gears into my mustang. I would recommend you come here
