4.8L, 5.3L, 5.7L, 6.0L - LS1 LS2, LS6, LQ4, LQ9, LM7 Rocker Arms with Bolts and Pre-Installed Trunion Kit.

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?"

Great product

7.3L Ford Powerstroke Head Stud Kit 1993-2002

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.

Worked great

Quick shipping, product well packed

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!

It’s a great tool and did the job

Thanks

Thanks

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

So far I'm impressed with them. I haven't installed them yet. Was a little concerned when I opened the shipping box and found 3 of the nuts out of the main box. But all was good.

I ordered before pulling my 2004 5.3 LS heads off. I take responsibility for the purchase. However, my particular motor out of a 2004 Yukon had the long studs in it so I was unable to use. Don't plan on returning as I have already opened the box, so they will sit for my next project or be sold on Market Place. Just take note, if you have a 2004 engine pull it apart before ordering to verify stud length.

The studs were great quality came with nice sockets and everything we will definitely be using them again at our shop

They have very good quality and arrived very quickly. I am super happy.

easy to install if not dumb like me, should have been a walk in the park watched vids and got her done.
