do not treat head studs like ordinary bolts. Clean and chase every block thread, verify hole depth and any fluid passages, then apply the supplied assembly lubricant only where specified—especially on nut and washer contact surfaces.

Took the gamble on these. Ive installed arp studs for customers and I did these in my truck. Few thousand miles now and no issues. I can’t say they are better than arp but I can say they are just as good for just half of the price.

Coolant Reservoir for 2011-2019 Ford 6.7L Powerstroke Coolant Overflow Tank | SPELAB
Good quality coolant tank with fair price!

First off I purchased this intake horn/w grid heater relocation because of the price and the heating element came as a kit. I am not a truck mechanic and this part wasn't very easy for me to swap out. The parts were shipped extremely fast and well packaged this intake horn was installed in conjunction with Spelab's rid heater delete kit. I was also nervous to do this swap myself because I haven't messed with any of these parts previously. But Praise God I was able to take everything apart and install the new parts without any issues. The videos were alright also looked up a few videos on YouTube to get a better idea of what I was up against before I started. Overall Spelab has been a great experience, all the parts were very nice looking and well made. I will definitely do business with Spelab in the future. I am considering doing the head stud kit.

Works great on my 08 f250, thank you spelab!

Billet Aluminum Valve Cover for 2008-2010 Ford F250 F350 F450 F550 6.4L Powerstroke | SPELAB

It’s an exhaust not really much to screw up. Exactly what I thought it would be.

Installed on my 2015 ram. About 10 hours start to finish. Also did a valve adjustment. So far so good, doing a hot retorque in the next few days, but I’m set on max, 200hp, tune and it sounds amazing. If your deleted and tuned you need these.

Muy buena calidad y excelente servicio. Dios me los bendiga

Easy to install looks great 👍🏽

Extremely Happy!!

much cheaper than big brand and seems good quality, thank you Spelab.

Price was great w heavy discounts. Great 5R110 6.0 powerstroke aluminum, Red, deep pan. W bolts and gasket. Great packing and instructions.

This kit came with everything I needed to get the job done. There's a great SPE lab video online for installation help. Every piece felt quality and was simple enough to put together. Had extra hose after running all the way to the back of my rig so there's plenty provided. I just ran mine to atmosphere so there's a popcorn sound at the back of my rig now but it doesn't smell terrible. Definitely recommend this upgrade for anyone who wants a healthy engine. As for how hard the installation is, if you can change the CCV box you can install this kit.

Installed this SPELAB thermal bypass valve alongside a deep pan upgrade and the setup works flawlessly. Trans fluid temps drop fast and stay right where they should be.

The overall fit was great and the build quality feels solid. I noticed a past review complaining about the O-rings being the wrong size—just wanted to clarify that those O-rings aren't for the bypass block itself; they are meant for the metal threaded filter adapter. Don't let that review throw you off. Solid 5 stars!
