CUSTOMER TESTIMONIALS

Tim W.

The boys over there at R&R just got my 6.4 diesel back up and rocking. She was real sluggish when I brought it there but not anymore. We just took it on a 800-mile trip yesterday. Mega torque. Thanks R&R for making this super duty run like a rocket.

I was having a miss and it turned out to be a cracked head, and they did a complete overhaul. They got it done in about a week and half, which is pretty fast for a complete overhaul! I’d definitely send someone in need to R&R Diesel Truck Repair!

Owner of Redwood Auto Sales –2008 Power stroke Service Truck

This is a pulling truck and it just wasn’t pulling like it used to. They tuned it and serviced it and apparently all the fuel filters were plugged and it had to be several things, but it has never run this like before! We went from having no power to twice as much power. We prefer taking our stuff to someone who knows what they’re doing. Our truck was there for about 24 hours and it was ready to roll! We are happy with R&R Diesel!

We work the snot out of this truck. The head gaskets were going and had 200,000+ miles on it. I was so impressed. The truck has more power than it ever had! It has better fuel economy too. I have never gotten service like that before!

I heard an ad on the radio and thought I would give them a try. I hadn’t had any luck going to two other places before. I was having electrical problems and they actually came up with two solutions I’ve never heard of before. I haven’t had any issues since and it's up and running again. I would definitely recommend R&R Diesel Truck Repair!
