It’s far better than the oem crap. I didn’t want to spend the money on a part that would crack again. This pipe was affordable and met all my requirements.
The turbo piping kit that comes one these engines from the factory are known for blowing out and causing issues.
The Xotic upgrade replaces rubber with high temp silicone, plastic with aluminum. The piping is high quality and goes on easy.
This what Ford should have done in the beginning.
Thank you Xotic for making a product that will stand the test of time. Very happy how easy it installs and how great it looks too!
Purchase and delivery were very easy and fast. Opening the box, there were no instructions. Included was a sticker that had the website misspelled. You should really fix that. I was able to find one YouTube video on how to install and that was extremely helpful. A one sheet diagram of how it should be assembled should help the buyer a lot. Taking the old cold pipe out was easy and installing the new one took a little over an hour as I was very careful to ensure the clamps were installed correctly and tight. The pipe is very high quality as well as the silicone and aluminum sleaves.
I have not installed the parts yet, but I ordered the milled rocker arm pedestals and the head stud kit. To say that I’m impressed would be an understatement! The packaging is so well done it blows my mind!
I was in a hurry and impressed with the free 3 day shipping, Can’t beat that! I’m definitely happy with this set.
They seem to be working good and they were easy to install just wish the packaging was a little better because the assembly line broke inside the box
My project began as a simple top end reconditioning for a classic with high mileage. It progressed into a complete rebuild and when I explained this to the sales team, why I had missed out on a discount because I did not order the complete kit at first, they offered me a discount code to help make it happen. The chaser taps are very well made and do just what they are supposed to, clean and straighten the threads without removing any material or 'cutting'. Xotic is not misrepresenting an important tool but making the right tool for exactly the job you came looking for help with here. I have even more confidence that their engine hardware will perform just as well as intended. The support chat people were readily available to help answer questions like "which size taps do I need?" And "are you sure this is for chasing and not for cutting?"
Install went as expected. Studs felt good and strong when torqued to spec.
6.7L & 5.9L 24V Dodge Cummins Head Stud Kit 1998.5-Present
While installing head studs on my 12 valve Cummins I cross threaded one stud. I contacted XOTIC through email and paid the invoice online. Part arrived and my truck is up and running. I was very happy I didn't have to buy a whole set. Thank you. Excellent customer service.
Great kit, everything packaged and separated nicely. Install went flawless with no issue.
They look great ! I can’t wait to install them.
Like an idiot, I damaged the threads in my vehicle’s crankshaft when I went to remove the harmonic balancer, and I needed a way to repair those really important threads in my engine. Xotic Performance came through by being one of the only online providers of this particular tool. Not only was I able to easily repair the crankshaft threads but I was able to continue with my engine rebuild project. I couldn’t have done it without Xotic Performance.
Great product!!! Definitely as good if not better than ARP studs!
Looks great and fast shiping not install yet but look amazing and good price
Appearance, packaging and presentation are great. Minor issue with instructions, but easy enough to figure out if you look up the arp stud install instructions. My directions had 2 number 1 bolts and no number 7 in the torque sequence diagram. They seem to be a good alternative to ARP if you want something a bit more budget friendly. Time will tell.
Great people to work with been sponsoring my trucks on TikTok for a little while now 100% love there products
