    Glen and his Team did an incredible job on my 2025 F250. From the suspension to the custom paint work, this truck looks incredible and drives even better. The attention to detail is without a doubt the best I have seen. BlackJack Speed Shop is the only place I will take my vehicles. Thanks!!!

    Took our Tahoe in to get fender work done/trimmed for the lift that was installed. Drove it to eat, and then home. Felt something in wheel but couldn't figure it out. My wife almost got in accident next day with our 4 kids and was left stranded and found the lugnuts on front driver side to be all very loose. I contacted restaurant and there was no footage of tampering with lugnuts. Very concerened that it accidentally happened at the shop, I sent out contact emails to try and get at the bottom of it and got no response. The owner Jason called me later and said he watched video from inside the shop that the lugnuts were never touched. I will never know what happened. But him reaching back out and watching video and holding his guys to a standard is enough for me. Have done work with them often, and their work has always been positive.

    Billy at Black Jack Speed Shop took care of me and my 2022 Corvette Stingray in Red Mist metallic tint coat, I first spoke to him from anybody else at this shop and he Met and Exceeded my needs which were to get my radar detector installed on a 1LT which Is difficult thru the back of the mirror and they pulled it off with the magic of Jack who worked on my car, then they powder coated my ugly light grey factory wheels a high gloss black metallic and installed a Blue Attack air filter and finally my Corsa Extreme cat back muffler delete with AFM valves and That was my Favorite mod to the car because Now it sounds like a Real F1 Supercar !!! Thanks Glen and Gary and Jason the pickle who gave me a ride home when I dropped off my Vette to get all this work done !!! Amazing shop and I Will be coming back for more work on my car :) Mark~

    There was an aftermarket dual-exhaust system installed on my 4x4 Tundra CrewMax. The dealership wouldn't touch it and when I called BlackJack, they were more than accommodating and scheduled an appointment to take a look at it right away--even though they did not perform the original install. Turns out, it was pieced together with some modifications and welding that weren't supportive enough to hold the weight of the tailpipes. Blackjack patched it up and installed a bracket that lasted for awhile but with the weight of the exhaust (and my girlie driving... :)), it came loose again. Twice this happened and BJ was gracious enough to take my truck in and fix it each time it happened--at no cost. After realizing this wasn't going to work, I returned to BJ to order a new MagnaFlow exhaust system and install it on my truck. I was so impressed with their customer service ethic that I didn't hesitate to also have them order and install a BDS suspension lift, Fuel wheels, and 35" Toyo M/T Mud Terrain tires. They also price matched the lift and parts. Their prices are extremely competitive, their products are trusted name brands, and they stand behind their work. Alas, my truck was approaching 50K miles, so I traded up to a Jeep Wrangler Unlimited last year. I purchased the Jeep with the lift and accessories already installed by the dealer's outfitters, so I was a little uneasy not knowing much about the integrity of the install. Again, even though BJ didn't install it they willingly, and without question, were able to check the alignment and the aftermarket lift that was installed on the Jeep. They also caught that the factory lug nuts were erroneously installed on the Fuel wheels the outfitters placed on there and were stripping them due to incompatibility, so they replaced them with spline lug nuts and also rotated the tires--all at an extremely reasonable cost. I also recently got rear ended and was able to get in and out quickly for an estimate for the rear bumper with no appointment needed. Since the parts were all custom parts, I preferred to have BJ handle my claim, rather than put it in the hands of the dealer. I really appreciate the fact that I'm a female and I can walk in here (and not know a whole lot about all the inner-workings of my vehicle) and they don't try to take advantage or talk down to me because I'm not a car guru. They go above and beyond and raise the bar when it comes to valuable service. As long as I have a vehicle, I will be coming back to BlackJack for all my customization needs.

    I've had two dealings with the Blackjack in my truck-driving history. The first was in my 2014 F-150 where I had Line-X sprayed in the bed. The second was in my current F-150 where I had a deer guard, running boards, Rhino liner (they no longer do Line-X) and a trailer hitch installed. I have to say, while I didn't get back double my money, I did drive away with extremely quality work. I will pretty much leverage these guys whenever I need something done to my truck.

    They were not knowledgeable about the products they were selling and I never received a call back after asking for a quote several times.

    THIEVES!!! TRIED TO SCAM OVER A GRAND FROM ME. I'm going to be perfectly honest and first state…read morethat I looked up this place and they had great reviews so I was confident that they would do good work. I was wrong. I first spoke with Cam who is the owner, or at least one of them. I explained to him that I just wanted a 2 inch leveling kit on my truck. I went to drop off my vehicle and cam comes out and starts talking about how my tires look rough and asked me if it vibrates a lot when driving, to which I told him no, and they drove fine , he then stated that my wheels which are 24 inch seem to be a little large for the truck and it looks like they're riding on bicycle wheels. I again explain that I wasn't there for rims and tires just the level. After I left, he texted me telling me that he had some wheels that a customer did not want but he would sell them to me for a good deal. I asked him if they sat the same way as my current wheels to which he explained yes. Let me add that I was not in the market for new rims and tires. Again I only came in for a leveling kit. So I asked him if the rims did in fact, look like my current ones but only were 20 inches instead of 22 inch. I told him go ahead and put them on. after almost 2 weeks of them having my vehicle I came to pick it up yesterday evening with my wife and two young children. I looked at the truck in the tires and wheels did not sit like the original tires and wheels. They sat underneath the truck and had no offset whatsoever. I then went to explain this to Cam, and he was making up excuse after excuse . I told him I was not happy and again reminded him I was not in the market for rims and tires only because he told me they would look the same as my original wheels. I asked him to put on the original wheels and tires. did not want the current rims that he explained looked a different way. He then went to get his business partner. His business partner came to talk to me. He told me I would have to pay for the tires in full that they were taking off of the truck. I explained to him that I would not be doing that because that is not a service that they would be providing since the rims did not sit the way he explained so in fact, I would need, no tires. if I could pay for the work that was done so that I could leave but instead he threatened to physically remove me and that I would not be receiving my truck which is a 2021 ram 1500. he then told me I would have to call the police if I wanted my vehicle back. To which I explained how I was shocked that we're even getting to this point since the tires were not on my truck, I will not pay for them. He told me that they were used tires now that they took it on test drives with the rims, that again did not sit like he told me they would trying to sell them to me. Again, let me remind everyone I was not in the market for rims or tires. This would've never been an issue if he owned the mistake and said I'm sorry they don't sit the way your old rims do my apologies. Or if you saw that it sat different if you let me know within those two weeks that they had my vehicle that would've been another option. And steady waited for me to come pick it up and hoping that I wouldn't notice it. What a scumbag. And then to threaten me, and physically put their hands on me. What a joke. you know, it's awkward when your wife is sitting out side in the car and sees through the window that they pushed me. She texted me on the phone asking if they put their hands on me. If that doesn't say something. After that, she told me she moved the car to where she could see through the window and see everybody while we were arguing about the whole tire issue. Before he then told me, I had to pay for one tire just to get my keys. So I paid it in order to get out and gone. Trashy trashy people. I am attaching a picture of a text my wife sent me while I was in their office arguing about them trying to charge me over $1000 for tires that were not on the truck. They then physically pushed me and my wife saw it and texted me. Horrible experience.

    Did a lift 6inch lift on my truck, I dropped it off and a few hours later call a call from the shop…read moreadvising my ball joints were horrible and they decided to replace them without asking me. Shop advised me they made their decision to do it without my permission and sent me an invoice for roughly 900$ just for the lower 2 ball joints. I asked why I wasn't made aware of this decision and they advised the mechanic said it was horrible. Reminder the truck was in fine condition when I dropped it off it's not like the dam wheels were about to fall off. If you want decisions to be made behind your back and get up charged go ahead and let them work on your vehicle. Other than that the Lift was properly installed other than the sensors that weren't put on.
