Differential repair service near Riverside, CA

Excellent service. Prices are way better than taking it to a dealership and these guys know what they are doing. They even solved a break issue that the dealer couldn't figure out. Den G. Newport Beach, CA

Friendly and quick service.

Always warm and friendly, excellent service. Like the new outside seating area, for waiting if necessary.

Great shop very helpful quick service highly recommend

Overpriced with a "can't tell me sh*t" attitude. Maybe their great on old cars but as for my wife's 2010 Challenger they caused more issues then fixed and charged me 1/3 more then anywhere else to do it. Brought my car in for springs, struts, alignment and to go through and make sure everything was right. Did a motor swap and the shop before didn't tighten the lock nuts on my adjustable suspension so wanted it all gone over. Guy was mouthy from the start and bitched about the job the whole time. My front ball joints we're missing a lock plate (found out later), really obvious but they didn't say anything and put it back together anyway. Also missed my rear craddle bushings went bad even after bringing it back to them. This is a huge issue and made the car unsafe to drive, they said it was all good though. I call back and kind of question their knowledge since these basic and obvious issues were missed to which I was hung up on. My advice, find another shop and save yourself the agony.

I bought my Pontiac brand new in 1988. 277,000 miles later it's starting to have a few problems, especially with the fuel injection and passing smog. IS&R fixed its current issues in one day and charged far less than I had expected to pay. Good work done quickly for a fair price. Now I'm trying to decide which of its other problems to have them look at next. Craigs great to work with as well!!!
