Transmission System

Hi yooo sharing some tips to make everybody's life easier! Slip the rubber boots on before fitting the pipe, leave plenty of rubber past each clamp. It's an easy installation.

Great product/quality

The product was delivered sooner than expected and the product is very well made and added a nice touch to my truck.

Surprisingly fast shipping and decent quality with half of big brands price... will come back!

I was already planning to replace the radiator and coolant tube, so getting the reservoir included made this a great value. Parts arrived well packaged and everything looked good out of the box.

The aluminum upper coolant tube is a huge improvement over the factory plastic piece. The whole kit looks great under the hood and everything went together without any major issues.

Sounds great, had all the hardware good quality metal and was easy to install only con was had to take off the spare tire to install.

Main challenges are removing and sealing the factory crankcase-breather hoses, then transferring the factory O-ring without stretching or mis-seating it. Cap every disconnected factory port/tube correctly, lift the old cover straight up, keep debris out, and route the new breather hose safely—zip-tied away from moving/hot parts. Start all six bolts by hand, tighten from the center outward, and use only 4–8 ft-lb. Be gentle to avoid scratching anodized covers.

Good quality and half the big brands price love itttttt

Great company and great products i was referred by a friend

Definitely a noticable difference over stock, and looks better as well!

I used a different oil catch can because it was “cheaper”. It just made a mess of my engine compartment. It couldn’t handle the pressure of the Cummins. Should have gotten this one in the first place. You get what you pay for! I have alot of SPELAB parts in my truck should have known better. Love the setup, easy to do yourself and now I don’t have to worry about it ever again. Set it and forget it! Love SPELAB!! Set up looks amazing!!!

The kit came quickly and wasn’t missing everything. The finish of the billet parts it nice and so is the powder on the pipe. Drove 2000 plus miles with with on and have had zero issues.

Loved the kit good fit and finish and easy to install. The little extraction tool helped immensely for that pesky bolt on the back. I purchased this kit because of the good reviews and I seen one on a 2018 Chevy Duramax that had been fully deleted and was asking the owner questions about the kit and where he bought it, he said SPELAB it was well worth the money and made it easier to put oil in the truck and yes does make it a lot easier to fill the engine with oil and if the old plastic ccv system cracks do to heat and and age it pushes oil on the engine and could cause a fire so it was well worth the money and piece of mind. So if you are looking for a CCV reroute kit I highly recommend this kit.

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.
