Head & Main Stud Combo Kit - 2006-2010 6.6L Chevrolet Duramax LB7 LMM

Second set of head bolts and crank bolt I've used on 2 seperate builds, work great and price is great!

Quality product looking for a 2 piece though they wouldnt return product after 30 day window.

They were every thing they said they were on time.and just in time worked perfectly 👌

Thr shipping was fast

Buen producto

The banner you sent arrived on my porch big white bag ,had a hole in it only thing in bag was a white plastic cap (i assume from end of banner)
I really appreciate all the parts and at a good value !

Best studs and quality good customer service in

Love them. Twice as thick as my factory covers.
Tried 4 different companies with new gaskets and never could get them to stop leaking u till these new badass covers. Thanks for offering a great product….. jay.

Exceeding my already high expectations from the packaging down to the finished results. Came with everything I needed, looks AMAZING and shipped extremely fast I was in shock how quick it was on my doorstep. Extremely satisfied.

The customer service department warrantied a whole brand new set of head studs bc the head of one bolt twisted off. They must’ve shipped them next day air bc I filed a claim on Friday afternoon after speaking to a nice lady and the new studs were in my hand Sunday morning. You won’t find any better people that stand behind their product.

Worked great fixed my truck !

Great

Great product worth the money

I installed Head Stats and it was easy, and they're doing their job. Plus, they're cheaper than other brands. I recommend.

Very well designed kit.

Haven’t had a chance to install head studs & pedals yet but shipping was very fast

perfect fit

Super fast shipping and more than enough lubricant for head studs on a 12 valve Cummins

Will continue buying xotic. When they have great product quality, amazing packaging and shipping, and the best customer support in the industry. Well worth it in my opinion

This is the only set of stand pipes on my 05 that have actually lasted, ive been through cheap ones, ford ones, after lots of research I came to this company and the xotic ones are the only stand pipes and dummy plugs that have held up to date.

Highly recommend and even cheaper then oem.

Great Product. I’ll tell all my friends!

Great quality and fast shipping

If I had to rate this install it would be rated at (A PAIN IN THE A) lol! I have installed a few of these before on Ford’s different brands ofc and never had issues. Without a doubt the dimensions are a little off on this kit but after a few f bombs I was able to get it in. The bottom coupling is sitting a bit “awkward” but all in all decent kit for the price. I’d try to maybe adjust the bottom couplings size give it some more tilt towards the back of the vehicle and install would be a breeze.

Shipping was great.

AMAZING PRODUCT SHIPPING WAS AS EXPECTED BUT OVERALL AMAZING PRODUCT
