Blew my cummins 12 valve 60 miles east. While I was sitting on the highway for 3 hours I did my research....I choose accelerated Diesel ....great decision...real personal guys, no there stuff, no bullsh_t, I went with a long block, new everything, they scheduled me on time and just finished 2000 mile trip...no leaks..

Traveled from Washington State to South Dakota. About 60 miles into my 1300 plus mile trip, my Duramax engine developed a high pitched whine/whistle. They investigated and found a missing bolt from the EGR valve. Did a makeshift repair that got me home with no problems. Thanks for being an honest repair shop and not taking advantage of a stranded traveler!!!

Great shop, they diagnose and fix only whats needed and they do it fast and wont rip you off. 10/10 reccomend!

I never write reviews. However, in this case I must. The people were so nice and friendly. I was on a cross-country move and everything went wrong with my truck. They got me in quickly, diagnosed everything, and completed the repairs in a timely manner. I hope I can find a place where Im moving that even comes close to the level of service I received at Accelerated Diesel Service. Thank you to everyone who helped!!!

The truck with the sign for this company was speeding on Durango and leaving everyone in a cloud of black smoke. Seems like a bad business move.

Herod and his team were top notch!

If you want knowledgeable diesel or gas experts to get your rig running right, you gotta go to these guys.

I was traveling in the area from out of town and my truck broke down. This shop was awesome with getting me in, even though they were already busy. They fixed the issue quickly which turned out to be a minor fix. Great communication and honest shop. I would highly recommend!

Coming through on a cross country tour and discovered our 2003 Duramax Diesel in our Silverado was losing oil. They quickly diagnosed the problem and made specific offer in terms of cost and timeline. They were upfront in saying that they couldnt get to it for another 1.5 days. Then, 1.5 days later, they did the work exactly in the time predicted, even after letting us know that it could take a little longer. Price exactly as predicted. They documented what they found along the way on the bill. We were off on our way same day as work started. No problems since. We had an *excellent* experience with these guys! Thanks so much.BTW, having a huge camper (Lance 1121) on top of the truck was no problem in their shop. Plenty of clearance, including using a lift.

Great service and reasonable price...

HIGHLY RECOMMEND!We were traveling trough town on a road trip from California and in need of some help. We showed up at Accelerated Diesel after visiting two other shops. They took us as a walk in and had one of their knowledgeable technicians look at our truck. We were back on the road within an hour! These guys know their stuff and had exceptional customer service to boot.

Awesome service! Had my turbo replaced sooner than I expected! Not only great service but very reasonable cost. Cheaper than the dealership.

Great service techs at a fair price. Highly recommend this place.

These folks saved my Vacation. We were visiting Mt. Rushmore when our truck broke down. Nobody else in town was even willing to look at it, too busy (Sturgis week). These folks not only worked me in, they were able to diagnose and repair my engine the same day, on a Friday afternoon yet. Not only saving my last day on Vac, but also saving me an extended weekend in Rapid City staring at hotel walls. Could not be more grateful and the quality of their work.

Hands down the best diesel shop in western South Dakota!! Ben and Jared were very informative about what was going on with my pickup and always help me to understand what needs to be done to fix the problem.Very honest and fair priced shop.I know that I can take any vehicle to them and they will get it fixed correctly and in a timely manner. Thanks for all of your great work accelerated!

Great place always friendly people and helpful

Took two of my trucks to them, one with fuel problems and one with clutch problems. They fixed them both, reasonable price and fixed right. Would definitely recommend, theyll be my go to shop.

The staff at Accelerated Diesel are excellent. I have taken my F250 there several times for a variety of things and have found them to be efficient, honest, and fairly priced. I highly recommend them to anyone in need of a great mechanic! My pickup has been running like a champion ever since.

Professional and fair priced. I would recommend them.

The only shop I bring my vehicles too. The guys are honest and straight forward with your vehicle. They treat it as if it where there own. Call and keep you informed on what needs to be done before they start racking up a bill with out informing the owner. Top notch service.

These guys are the best diesel shop around!

I never got either name of the gentleman that helped us today but I will say they we very professional and were able to look at our truck as soon as we brought it in! Thank you!

We had our 08 Dodge Cummings worked on here and we were very pleased with the service. They had our truck done faster than we expected. If they quote you a price they will stay with that price. They dont try to sell you stuff you dont need. Very professional and friendly. I would definitely recommend them especially if you have a diesel!

I was from out of town and they fit me in quickly. Did good work at a fair price.

Traveling to Custer when out 7.3 diesel started acting up. Called them at 8 in the morning, pulled in at 830, and were being helped at 831. My husband is very particular about who works on his truck, but these guys were so thorough, knowledgeable and nice that he felt comfortable right away that they knew what they were talking about. These guys are true mechanics, not people to throw parts at a problem. Spent over an hour diagnosing our truck and the bill was much lower than we expected. Highly recommend to anyone in the area!

Great customer service. I had my Ford Super Duty towed to their shop, they said it would be two weeks. They had me up and running in less than one.

Excellent diesel (pickups)shop. Very efficient and fast.

Came came into sturgis this year truck wasnt driving good, got into town and accelerated diesel said bring it in. Really they were busy but they called the next day and truck was fixed. Real honest people!

Unbelievable service, hoping not to return but if I lived in Park Rapids I would trust my diesel to them!! Thank you

Great people to work with if u need your vehicle fixed

They diagnosed a coolant loss issue on my duramax and had it done ahead of schedule and at a great price. Highly recommend them

Fit me in on a super busy day to help me out while over 800 miles from home. Thanks for the great service and for fixing my emergency quickly and efficiently!

Great shop great work

Accelerated Diesel was recommended to us by someone who has had really good experience with them. We dont live in the area but stopped here while traveling across country. We went to Ben at Accelerated, desperate for help with a badly smoking pick-up with a new tuner. He figured out the problem (unlike everyone else wed talked to including the shop that installed our tuner in NC) and got it fixed by working with the tuners manufacturer. He got us back on the road in a truck which is performing like it should. We cannot thank him or recommend him highly enough!

Awesome experience, came in at 1100, my truck had an odd knock only at at specific conditions and one of the employees came out and checked it out and drove it around, told me what I figured, it was not a normal sound, and within 4 hrs later, I had an injector replaced and was driving the truck, all without an appt, great people very professional and couldn’t have been quicker, and at a very reasonable price. Highly recommend this shop for repairs, will definitely be using them for any major repairs in the future

We have had Accelerated fix three different vehicles for us and have been extremely happy with their work every time. Ford F450 with a 6.0, Ford F650 with 5.9 Cummins, and an Isuzu NPR.

We broke down in Custer State Park in the middle of a big storm with thunder, lightning, rain and 50-75 mph wind gusts. Jerod quickly diagnosed and repaired our car for a fair price and we were back on the road again.

I was traveling through town on work and had to bring my truck in. I was on a very tight schedule. They took care of me immediately without an appointment, and everyone was professional, friendly and I was back on the road within a half hour. If you are looking for a place to bring your vehicle - this is it!

Great service . They got us taken care of in no time fair price, and they had a cute puppy to play with while we waited Thanks again

This is an Awesome company we was traveling and developed overheating problems with a Duramax diesel everyone said it was a Head gasket problem which wouldve been big bucks the folks at accelerated diesel diagnosed it with a dirty radiator and needing to replace the clutch fan which was under a $500.00 fix. We had eight children with us and all I can say is a big THANK YOU to Eccelerated Diesel you was able to help us complete our vacation and made eight children very happy. 👍

Saved my tail with a new transfer case for my truck which broke on the back half of a two week roadtrip. These guys not only saved me thousands on the part they also repaired the truck for a fair and reasonable rate in labor.

Good mechanics getting to be more of a wait to get in

Great honest guys fair price the maintenance is worth the wait

Great people and work

They have a small shop, but eager to help trouble shoot a problem. Unlike other shops that want a shop fee before they will help you.

I deal with Jerod and the guys at Accelerated Diesel. Great bunch of guys, want power and performance these guys are the one.

Quick service, decent customer service for this area, fair prices.

Good service

Great customer service!!!
