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!
Surprisingly fast shipping and decent quality with half of big brands price... will come back!
fits well, would be better with instruction.
love this red! Customer support is also very helpful. Hope it will last.
Love it! Fits my 2017 F250.
The fitment was fantastic And it went together really well and fast
Great shipping. Great product. Was easy to install even though I had to cut some pipe off but overall happy with product
Solid intake manifold, no fitment issues.
Fit perfect and was of high quality material I have had the plate on my truck for about 2 weeks now and it is working great thanks SPELAB
The cold air intake was easy and fast to install. it looks great and boosted my truck up a little for performance without breaking the bank. it’s the best bang for your buck even if your truck is stock or built it’s worth the money
hard parts are amazing and everything went together great
Transmission System FAQS
Four categories: Differential Covers (20 products), Transmission Pans (3), Thermal Bypass Valves (1), and Transmission Line Kits (1). Covers span Ford, GM, and Dodge Ram platforms.
Thick cast aluminum or iron construction adds cooling fins that lower differential oil temperature by 15–25°F during heavy towing. Internal baffles prevent fluid starvation on inclines.
