I worked with Justin, I'm from out of state and the transmission went out on my RAM, they had a built transmission on hand, and were able to swap it in on the 26th and have me back on the road by the 27th. My truck runs better than it ever has now. If you want your diesel pickup fixed right in a timely manner this is the place to go.

I had been traveling across the state to have my previous work done, they were great, but I needed to get established with a local reputable shop. I know Jake and Justin and their reviews are awesome so I went in to get established and have them check over a few things. I was very impressed with their customer service, honesty, and timeliness. I’ve since had other work done and still have the exact same positive thoughts towards the shop. I would highly recommend this shop to anyone that needs regular maintenance or performance upgrades. I wouldn’t quite eat off the floors but it’s pretty stinkin clean shop and they are busy busy.

I recently purchased a used Chevy Cobalt and being a single woman, I needed to take it somewhere I could trust. Jake did a top to bottom inspection on my car before purchase and gave the car a thumbs up, said it would be a solid purchase and I would only need to get some new front brakes eventually. I went ahead with the purchase and the car has lived up to his expert opinion and it has been a gem! I went back to Jake and had him install the brakes at a later date and just like before, he was professional, kind and efficient! A great deal, great price and you cannot beat the expertise. I highly recommend Jake and his crew!

Really great shop! Really great team of people! Jake and his crew did an amazing job on my 2006 Ford f250 6.0l. I had some injector problems and they replaced them fast and at a good cost! Then few months later I blew a transmission and I called Jake and he told me tow it down and we will get it fixed right away! I loaded it on the trailer and brought it to him. We talked about transmissions and pricing and he helped me alot! Him and his crew got it done really fast timing and even did a over check of everything for me! Really honest crew and willing to help get anything done Great! Great crew to have any type of diesel engines done by! Jake and his crew will always be my diesel guys!

Had a 2004 f350 6.0 (diagnosed) from them. Told them truck just stop running on the road will turnover but not fire. They sent me a massive list of all this stuff wrong with it saying it had no compression needed new motor. Turns out it was two o-rings on two injectors and an egr valve. They quoted me 26k for an engine. Spent 600$ truck runs fine. Another rip off group of mechanics don’t take your diesel here if you can help it. They claimed the motor had no compression charged me 700$ for new battery cable ends and a (diagnostic). Scam artist.

JBJ Diesel offers exceptional customer service. The team in the office and the crew in the shop are incredibly helpful and knowledgeable. I have faced numerous issues with my 2014 RAM 3500 6.7 Cummins, and they have provided excellent support while assisting me with some of my DIY motor work. Tony is a pleasure to work with, and I highly recommend JBJ Diesel for anyone seeking a top-notch diesel shop.

They do great work. Had a 1991 international 4900 that they did work on. Work that was done was clean and professional. I will be taking my truck back for maintenance and repairs.

Fantastic shop, highly recommend, my go to guys. I had my truck at another shop and it sat for months with promise after promises of getting it fixed. JBJ fixed it in a manner of hours, communicated the entire process with me and recommended additional proactive repairs. I won’t be taking my truck anywhere else JBJ is saved in my phone and I’ll be referring them to anyone I know with a diesel.

Just cause someone’s name is Terrell on Google doesn’t mean that’s there real name. Yes you did work on my vehicle and yes you scammed me and yes I’m writing another review. You guys quoted me 26k for a new motor and it was 600$ in parts truck ran fine. So no you didn’t work on a (Terrell) truck but you did work on an 04 f350 your records will show that very recent. Do not go to this company they are scammers 700$ for new battery cable ends which I didn’t need and a massive list that amounted to a new motor totaling 26k. Please go somewhere else they are not honest or must not do there due diligence to be 100% sure they are quoting you with what’s actually wrong with you’re diesel.

Clean, professional , friendly, the best experience I've had working with a shop. Drove 7 hours from out of state to have hydraulic cam and lifter setup on my 2022 cummins retrofitted as well as some other upgrades. Work was performed on time and on budget even when dealing with delays on parts suppliers out of their control. The shop is huge and extremely clean. I very rarely let people work on my vehicles and have really high expectations. Jake, Tony, Tran and their crew set the bar for professionalism with top notch clean work. They have my trust and I'll be going back to them if I need anything else big done!

We have been loyal customers for this group of mechanics for years , through all of our experiences, they have been incredibly professional, honest and trustworthy efficient and the level of expertise of their mechanics is unparalleled. Everyone from the front of the shop to the back has our respect and admiration. Thank you for everything guys - if you have a diesel truck and you’re going somewhere else you’re doing yourself a disservice. Take your equipment to Jbj. You’ll be glad you did.

These guys got me in their shop without much notice and all taken care of. I ran into some last minute issues with my car the night before my dyno appointment the following morning with a remote tune session. Jake and his crew crushed it staying late and coming in early to get things rolling on it for me! Dyno appointment happened and one step closer to finishing my project. These guys know their stuff and make it happen! Thanks Jake!!

They really do great work. I had some modifications done to my 16 Duramax when I bought it in 2020 transmission fuel and air and have not had a problem for 130,000 hard miles. Jake really knows his stuff and he makes sure it is done right and employees are very knowledgeable

This is BY FAR, THE BEST SHOP i have been ever. Cleanest shop you will ever see, all the staff is more than profesional. Show up on Monday with a damage VGT ACTUATOR on my Ram 3500 2018; Justin (Tech) scanned the truck and in fact the VGT ACTUATOR was bad. After Jake and Tony make few calls, they were able to find me a BD DIESEL PERFORMANCE VGT TURBO, i use this truck for hotshot trucking, so i had to have the engine brake working. Long story short, turbo show up next day, and Justin jump into right away and knocked down in just 7hrs. Price was fair, Customer Service was OUT OF THIS WORLD, all the team was super friendly. Couldn’t expect more out of a shop! Please Tony and crew, next time i visit y’all, make sure you have a coffee maker machine! Lmao! Thanks once again for all your dedication!!

We brought our Tiffin Motorhome into JBJ Diesel in Caldwell Idaho to have the brakes replaced, mind you the existing brakes were only two years old with under 20,000 miles. But that is another story. We dealt with the service manager, named Tony, he was honest and straightforward which is seldom found these days. I would highly recommend using JBJ Diesel for any repairs you might need on a motorhome or any diesel vehicle. They were awesome!!

JBJ diesel has a dyno system to see how much power a vehicle is actually making to the drive wheels. I called and the owner / operator Jake told me to bring my 2011 Cadillac CTS-V over to check current power levels before doing additional mods to the car. Thanks Jake for working me into your busy schedule for some dyno pulls! Very appreciated! Will be back after the mods are completed.

Can’t say enough good things about this shop last year on Father’s Day I broke down on the side of the road with the dreaded fuel problems on my lml, got it towed to JBJ diesel they got me going on a cp3 conversion kit. They explained thoroughly how the procedure is going to go and since they had the cab up i wanted to get prices to do as much as my budget could handle and these guys were on point new cheetah vgt turbski that just screams! Coolant upgrade, new 5g air dog lift pump, they got rid of that problematic GM fuel housing I didn’t even have to ask they just did it! Which was a plus for me. I actually can’t even remember everything I had them do. Which brings me me to my next visit with these guys, took my truck in a week or so ago with some death wobble action going on. So they hooked me up with the lifetime warranty Kryptonite front suspension and while it was in there I had them just go ahead and tune it for all them parts they put on it my previous visit and it’s a completely different truck it’s almost unbelievable the difference they’ve made to my truck, it 100% lives up the the name silverback now! My truck will only go see these guys when I need something done. One of these days I’ll have to buy these guys a beer or 3.

I’ve been to a lot of shops around the valley, and JBJ is the only one I truly trust. Their integrity, communication, knowledge, quality of work, etc. are unmatched! The whole team is professional, respectful and absolutely awesome! I can’t recommend them highly enough!
