Straightforward and easy installation is definitely holding up to what I’m using the truck for great product so far!

2006 Ford f350 4x4 cab and chassis, worked great. Just what the truck needed. The stand pipes are hard to separate but with some muscle they are able to come apart. The green o-ring was the only part I had no idea on where it went.

I haven't installed them yet, have to replace the camshafts. bad rockers arm deep grooved the lobes

I've been running these in my truck for almost a year without an issue.I had just done a bunch of performance work to my truck (injectors, turbo, CP3, tune, etc) and blew a head gasket. @truckmaster07 recommended this brand and I see why. Obviously well made. Comes with sockets, an extra long Alan wrench, grease, and VERY clear installation instructions. And the packaging is an experience by itself. So much attention to detail. Not to mention the fasteners have probably the best finish I've ever seen on bolts, nuts, and washers (I'm a quality Engineer with machining background).

Easy to install first time using them like how everything came in box and prepared nicely packaged

I used this on a big block setup, and the hardware felt right for the job. The weight is what I would expect from real engine fasteners, and the material feels strong and properly machined rather than lightweight or questionable. The 12-point heads are clean, and the fit was solid during installation.This is not the kind of part where I want to gamble on poor quality, and these felt consistent from bolt to bolt. The versatility is good across the listed older big block applications, but I still checked fitment carefully before using them because engine parts are not something to guess on. Installation was straightforward, and the instructions/spec information were clear enough to follow with normal engine assembly procedures.The durability is the main reason I like them. They feel like they are made to hold torque properly, and the finish looked clean out of the package. The value is good compared with piecing together questionable hardware, especially when doing a repair or build where dependable fasteners matter. I would use them again.

The intercooler pipe is fantastic and a huge upgrade over the stock pipe. Had a small hiccup and the service department was on it, took care of everything, and made sure it was all taken care of. Will definitely buy more products from them!

I purchased this to replace the stock FOMOCO cold sise charge pipe for a 2018 F350 (two of which previously failed). I purchased this after reviewing several videos. This particular item seems to be made of high quantity material. Finish and durability seem good out of the box.4 stars because, while it does fit, fitment is marginal and installation is a little difficult. Clamps are sufficient, but require adjustment and tightening after running for a few hundred miles.Truck seems to have a little more pep.

Balancer bolt is just as strong as competition but costs less and comes with extras!

The bolt had me upon opening the box. Very substantial, well made, excellent quality and a very thick washer. This thing is built for business. Comes with absolutely everything you will need to secure that bolt to the crank; socket, lube, air freshener… ok, so prob don’t need the air freshener. But the other stuff, wow. It went on without any issues or fan fair. Would buy again.

Ok

I pulled these covers off my '96 Ram 2500 when the original covers started leaking oil around the edges. The fit is perfect with no forcing and no gaps, and the factory bolt holes lined up perfectly with absolutely no adjustments needed. To install them, I removed the old valve covers and installed these using the factory screws. The seal around the outer edges of the covers sits flat against the valve cover, and there is no movement or rocking once it is bolted down to the head.Oil containment was the main reason I wanted these covers. Additionally, the finish on the covers is aesthetically pleasing in the engine compartment without looking overly "done". The sealing ability of the covers has also held up well so far under normal driving conditions and occasional towing. Time will tell how well they hold up over the long term, but I feel confident they will stay in place because they fit their respective locations well.

Great quality

Good brand had a high pressure oil leak changed them out in August of 2025 and still holding strong would highly recomend

Perfect fit on my 2021 Super Duty. It took me about 40 minutes to install. Make sure you lube the fittings up.

Have to work with it to get it on the vehicle

These rocker arms feel like a solid upgrade, especially since the trunnion kit is already installed. That saves time and makes the job a little easier compared with pressing everything in yourself. The parts look well made, and the bearings feel smoother and more secure than the stock style. Installation still takes some mechanical knowledge. For an LS build or replacement, this set feels strong, clean, and worth the price.

The quality of this head stud kit appears to be excellent. Everything is well packaged with the necessary components including the studs, nuts, washers, lubricant, and instructions, providing a sense of completeness. The part for engine is imperative to ensure the compatibility beforehand in order to avoid buying the wrong product. Installing such a component may not be an easy task for beginners, however, for those who are already working on the engine, it should do just fine.

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

This Will be great for my junkyard LS refresh on a budget. While I have it out and torn apart I figured it would be good to replace the head studs and this fit the bill for my budget.
