Good stuff

Awesome studs!!!

Product showed up have used it multiple times and no issues ever always works like it should and actually prefer it over the over priced arp will definitely buy again cause I own a shop and have not had issues with then at all even after years of use

Great product

Hit these guys up for some great head studs upgrades!!

So far so good

Quality packaging and seem to be good quality studs, I’ve only put 40 miles on it since complete overhaul so time will tell

Shipping was very slow but packaging was great and installation was easy

Received wrong item

Received wrong item. No phone number to call then when we were finally answered through email we were told we’d have to wait to get our item since they didn’t offer overnight or 2 day shipping so the truck was out of commission for an extra week and a half while we waited. Once correct product arrived it was a great product. I’m just not a fan of the company.

Installed on 1999 24v cummins

Packaging was nice shipped fast. Instructions easy to read. Truck runs great head studs holding so far. See how long they last tho

Works on 06 5.3L LS

Installed these on my 06 5.3L LS and worked great. Follow torque specs given. It was something like 25ft, 55ft & 85ft lbs. No stretch specs listed.

Seems to be good quality

Time will tell, but they look and feel good quality, torqued without any issue, seems like a good middle ground between stock bolts and arp studs

Nice Quality Kit

I used arp torque specs at 75 final.... 25 on the small ones, none broken.. be sure you have washers on the right side, plenty of grease to completely coat all threads and between washers and bolt heads with leftover, I think it was arp or jegs bolts that called for 75, seen people say 70 is plenty so I'm good with 75

Very high quality

They are comparable to the arp studs on another build i have. But this one includes assembly lube, a socket for the 12 point nuts and an allen wrench for the studs. Usually not an issue for a mechanic with all the tools but all my sockets are 6point except for a few for these type of jobs 😅, definitely a plus and nice to have. We'll see how well they hold up in a few months but so far im very impressed. Also the stuffs came with protective rubber caps on both ends and sealed inside an oiled bag, very well protected from rust and damaged threads. The washers and nuts came in their own separate oiled bags as well. So far i have zero complaints.

As good as arp but 1/2 the price and packaged with care

Parts where super nice and packaged very well and also have proper instructions. It will give ARP a run for the money

well packaged and quality

Purchased for subaru ej20/ej25

with the tools and documentation, i will come back to write a review after installation.


Feedback from the mechanic: he said they are very very good material and very high quality,

Very strong head studs, the mechanic was very happy with installation process and performance

Top grade , sick price

These are bad ass head studs. Just remember to follow the torque specs from Xotic not OEM subie specs.. insane clamping force on 2004 EJ20 impreza wrx. Did a new head gasket is why I bought these

It is a nice kit came the sockets and wrenches. All the studs had caps on the so the would not get the threads beat up during shipping. The price was reasonable and the shipping was fast

Solid quality

My installation manual was lacking some information for my head studs. But the quality is amazing and the packaging is top notch! Came with everything needed.

The studs arrived to Australia quickly. Threads were capped to protect them. Installed without a problem and everything you need is included except the torque wrench.
