Unlock the full potential of your Engine build with our upgraded head stud options. If you're building an engine for high horsepower, these head studs are essential for higher power levels.

When you're talking head studs, you're ultimately trying to increase clamp load onto your gasket. To get more clamp load, you need stronger material, or bigger studs.

Stage 1 engine builds should go with the 10mm CA625+ head studs. These studs are proven reliable to 800whp with a stock or Cometic MLX head gasket. This option is as big as anyone with a non-sleeved block needs. This option even works well for Stage 2 engines that are not using sleeved blocks.

If you're going sleeved engine and are going to put it to work, your best bet is to step up in stud size. Our 8740 Chrome-Moly 12mm head studs are perfect in-between step. These studs are a very affordable option that is good for over 900WHP. They're the same thread size/pitch as the 12mm CA625+ head studs, so you can always step up later when you refresh your engine. BLOCK MACHINING AND HEAD CLEARANCING ARE REQUIRED, ALONG WITH A SUITABLE 12MM HEAD GASKET.

If the sky is the limit for your build, it's time for our 12mm CA625+ head stud option. There is no bigger head stud available for the platform. These studs are good for over 1200WHP. Do it once, do it right. BLOCK MACHINING AND HEAD CLEARANCING ARE REQUIRED, ALONG WITH A SUITABLE 12MM HEAD GASKET.

All stud sets come with washers, nuts, and instructions.

Engine fitment for 4 cylinder Mazdaspeed DISI and Mazda MZR engines, and Ford Duratec and Ecoboost engines.

Just Okay
Color: Suitcase - Black
Speakers are crap, but you can connect others, which is good I guess. Simple functionality, probably best for the "turn the page" books for toddlers. The Black Keys are sad.

I love this!
Color: Suitcase - Black
Okay, I was born in 1985, of course I’ve always known that vinyls exist but never seen one work like live, forget about me putting it to play a record, so… this is my first record player I’ve ever bought, I did do some research before getting it and I was lucky to have gotten it because now it says “currently unavailable”, but I’m happy with my purchase and I do hope that Amazon make more of these for everyone who wants one, maybe even upgrade it a little bit… sounds good and clear but you can always hook it up to some speakers for more bass or volume. I haven’t tried the bluetooth yet so I’m not really sure what can you pair or not. It has Auto-stop so at the end of the side of the vinyl, it stops spinning. The briefcase appearance makes it stay on the vintage realm and is easy to carry and I liked the fabric used instead of vinyl-leather material like because they tend to deteriorate.

Nice

This was a Christmas gift for my son. He loves records. He was very happy with it. So far it works and very nice suite case where we can move it from one place to other.
