A ton of thanks to Jeremy and the guys in the shop. 6 hours from home. Coming back an a trip from Jarbidge Nv. The Duramax decieded it needed some TLC just outside of Elko. Called Jeremy up just after 1 p.m. He said bring it in. I could tell he had a loaded schedule, but he fit it in and got us back on the road before the end of the day.

NDRP was able to make an appointment quickly for my truck, diagnose issues, communicate with me about the issues, and fix the issues in a timely manner. Management is friendly to talk to and will stand beside the work they do

I was passing through to California and had a fuel leak. I was pressed for time. They got right on it, spent about an hr trying to find the problem but it wouldn't do it again. They didn't charge me for the time spent and were good company while I was waiting. Once I got home it took over 3 hrs for another mechanic to find the problem - so Neff's not finding it in the quick hr I had wasn't a surprise. I highly recommend them. Thanks Neff's!

These guys are the best. We were stranded and needed some work done on our diesel truck. They had us back on the road in 20 mins. Thanks a million to our newest hero friends. If Byron worked for me he’d be getting a sizable raise. We highly recommend. Thanks again. Ron & Jackie

I was over in Elko for the Ruby Mountain balloon festival and as one of the pilots, had an issue with my Ford F-350 6.0, a bad injector and they slipped my rig in front of other jobs to get it in and done. Top notch work, great guys and very knowledgeable. Reasonably priced for the situation too. Thank you, got me back on the road to the event and have not had any issues since (with that).

They did a bunch of elective work to my diesel; new Cold Air lines, Manifold replacement (original was leaking) and such. Great job, good service and kind. I LIKE THAT, just good people!

When you travel for a living your truck and its solid reliable functionality is incredibly important. While travelling across I80 my truck had its first major mechanical failure in the transmission. Jeremy was able to guess at the cause after simply sitting and shifting through the gears. they charged a nominal fee to investigate the precise problem and their findings verified his in seat guess... wow! Transmission needed to be rebuilt and it was not cheap, not their fault, but they were very upfront with costs and very reasonable with their fees. It took a bit of time to get everything in place but I now have my truck back and working great.

Neff's Diesel has my vote of confidence. Good work and thank you.

Other than the long wait to get into the shop (which probably goes to how well respected the shop is) once the truck gets in, things are done well and done on time as promised and at the price quoted. Keep up the good work.

Awesome staff! We were traveling from CA to MT for my husbands work. The turbo on his truck went out while we were en route with a 10k lb camper & 2 kids. They looked at his truck, while allowing us to set our camper up in their parking lot. Not just that but they ordered the part, had it sent overnight, & fixed the truck the very next morning. Also, they went out of their way to argue with the warranty company about paying for the part. We ended up having to pay out of pocket but that wasn't NDRP'S fault! I highly recommend this shop to anyone looking for diesel repair or performance!

Luke and Jeremy Neff run a great shop full of great people and excellent mechanics. Despite their very full schedule last July, they made time to inspect and evaluate my 2004 Ford Excursion Diesel that completely shut down 3-miles west of Elko. My kids and I were stranded, Luke gave us a lift to a local hotel, and they even let me stage my U-Haul trailer at their yard while we figured out what to do with our truck (which was totaled because Wayne's Automotive Center in Sparks, Nevada completed repairs and routine maintenance services so badly that the engine was a complete loss).

The crew at Neff's Diesel go above and beyond. They are merciful to those in trouble and in need, and I believe fair and highly competent. Luke Neff, beyond just being a nice guy, took the time to explain to me what likely happened to my engine and how it likely happened, and he made sure a mom and her kids were not stranded in Elko not knowing what the condition of their vehicle is and was. I will, forever, recommend the services of Neff's Diesel and validate the quality and personal mettle of individuals that work there (Luke, Jeremy, David, and the guys in the shop).My sincerest and enduring thanks to you all.

A lot a time and effort was put into resolving my exhaust manifold issues by this shop.

3 trips in to replace gaskets and even the turbo.. Turned out to be a defective BD replacement manifold , which NEFFs covered under their warranty.

My hat is off to them.. Thanks.

NDRP is my source for Amsoil products, and boy are they quick about it! If they don't have what I need for my next auto/truck maintenance project, they get it for me with outstanding speed. Cheerful, professional, and fast. I couldn't ask for more. The new facility is tops, too!

Great service and quick turnaround. I’m new to the Elko area and so thankful to find a quality shop that does honest work. I brought my truck in for an inspection. They were able to diagnose a few issues that I suspected as well as a few issues I didn’t know about. Staff was knowledgeable and friendly. Will definitely recommend them for any diesel repair needs.

Great work, and great system you have over at Neff's diesel repair & performance. I'm new to Elko and I was looking for a shop to work on my 2010 Ram 3500. I took my truck in cause my turbo wasn't working, they did a diag on my truck and sent me pictures and videos of everything they checked on my truck which was awesome how they kept me posted on what was being done to my truck. As I was waiting for the big ticket $$$ they figured out that all my truck needed was a flash (update) on it's system. They literally saved me a lot of money by being honest and my truck is now running like a champ! Thank you everyone at Neff's diesel repair & performance. I really appreciate your honesty and awesome work. Keep up the good work!

Left Spokane, Wa. pulling 5th wheel with Ford F350. At the end of first day the air conditioning started to intermittently blow hot air. Since it was Saturday , I could not contact repair shop until Monday. Arrived in Mountian Home , Idaho on Monday and called the Ford Dealership. The informed me they could not look at as they were booking into Sept. for appointments. As we were destined for Reno Nevada, I called Elko , Nevada and Reno ,Nevada and the story was the same. On the way to Elko the air conditioning stopped working totally. Scheduled to spent two nights in Elko and stopped by the Ford Dealer , now booking into mid Sept. They give me a list of names of repair shops to try. Went to Neff's and the person on the desk, Jessica, said she could get us worked in. I arranged for a rental car and the owner took us to the airport and picked us up after dropping of the rental the next day. We were back on the road in the time frame planned as we had to leave Elko on Saturday morning due to rv lot availability. We are grateful for the prompt service and the quality of workmanship . As it has been great to have a cool ride in 100 degree weather. Thanks to all at Neff's Diesel Repair.

Took my 2005 avalanche to several maintenance people to take care of the problems I had in the front in none of them was able to professionally diagnose and complete the problem .Neff’s diesel repair is number one in my book .

Traveling through and had a fuel leak on our duramax. Went there when they opened and they put us to the front of the line to have us out before noon. No extra charges for being out of towners or emergency situation. Very pleased with the price. Would highly recommend
