Ordered a S&B cai for my Silverado. Paid the advertised amount plus 45 shipping, waited a few days received no correspondence other than the automated order received. So I called the number spoke to a gentleman who said he would look into a call me back. The next day about mid-day I called again got voicemail which I didnt leave. A few hours later I get a call from them. I was told the order was being held (drop shipped) because the price increased by like 75. I was offered to pay the difference and get free shipping which made a difference of about 35. Which I did because honestly it was easier than waiting for a refund then ordering from another place. Once I paid the difference the order was shipped and received within about 2 days.That was just my experience, yours may be different. The guy was nice though.

I definitely would not recommend this company for injector replacement, my husband took our truck over to have one injector replaced, which they were fine with. We had already checked the balance rates and knew which injector was bad so he said well double check to make sure. Not bothering to tell us that it was $250 for him to “make sure.” So our original quote was $4-500. Now we just added $250. Then he called and said well we can’t guarantee that stuff won’t fall down into the other lines when we take them out. So, we made the expensive decision (we are a one income family) to replace all 4 injectors on that side which he quoted at $1900. We get there to pick the truck up and it is still smoking and we are at $2200 now, and the only response he has is that they can keep it and do some diagnostics on it at $250/hour which is their shop rate. Got it home and seen one battery and the compressor were left disconnected and bolts were missing from the turbo horn. We will not be back! That was one expensive mistake.

The staff here are incredibly knowledgeable in both gas and diesel powered vehicles, in not just basic maintenance, but performance upgrades as well.

Called Kingspeed told them truck Goals, Staff is very Knowledgeable. Good Price on some of the best parts and most of all the Customer Service Was above and Beyond. Any installation questions or problems Greg Was always on top of things.

Found out about this shop through a friend/ watching Greg_As youtube channel. Top notch service from people who use their expertise to the consumers advantage. They can tackle anything from wild to mild and work with whatever budget you present them. Fidelity for the parts you are getting was much appreciated. Even stuff thats on the budget side is quality they stand behind. Highly recommend for the customer service and expertise.

Chase, Michael, and the techs are very knowledgeable in the ever changing technology of the vehicle performance industry. They have done repair on my Duramax and also a full tune, delete, exhaust, and intake on my 6.7 Powerstroke. I will not second guess their advice. They know their stuff.

Awesome love the work they do

Stopped by the shop July 18th to have some work quoted, said they would call me Monday 22nd. No call !Called them Wednesday said theyd call me back. No call !Called them again the following week, still no call back !Ive been wanting to do some work to my 89 Dodge and had $3,000 to $5,000.00 budget, what does a person have to do to ?

Liked the web site. Seen that a youtuber that I fallow now works there was seeing if they carried alot of duramax parts and it seems more geared towards Cummins

Top notch place to do business! Highly recommend.

My husband and I have agreed this is the only place we will ever take our deisel.
