Harold G. 5/5 Verified

Piece showed up in good condition and was easy to install.

Carson S. 5/5 Verified

Looks way better than stock studs and last longer.

Jed S. 5/5 Verified

Fit perfectly in the stock location and is way bigger than stock and shipped fast. Would recommend full send diesel to anyone looking at these type of parts!

Dakota P. 5/5 Verified

I had a few questions about the install. I called and left a message and then shortly there after my call was returned with the answers I needed. Appreciate the help.

Scott W. 5/5 Verified

The billet heat exchanger looks great and is machined nicely. No worries about an internal failure allowing fluids to mix. It seems to be doing its job. It's more robust than the factory style cooler but I don’t believe it is quite as efficient based on warm up times I’m seeing. My only gripe is the bracket mounting bolts, they thread directly onto the cooler instead of passing all the way through and securing with nuts. Make sure to use thread locker along with the lock washers. As a rough guide, torque for M8 fasteners in aluminum should be 11-15 ft lbs, no torque spec is listed for the mounting hardware in the instructions.

It’s not bad, I was in a bind and needed a quick fix to get my truck back going. So first things first, the kit works. You can get rid of the steel lines and these will take their place. With about an hour and a half and a little research it doesn’t take much to get these hoses installed. However, I have some gripes about this kit. 1. You have to be very careful about how the lines are run to prevent the hose from kinking. 2. There are no p clamps or hardware included to hold the lines in place. To improve this kit, I’d toss some hose clamps, a couple bolts with some p clamps to hold the hose, maybe a couple pictures on where to run things too, or even total install instructions. Stiffer hose would be good too, in my pictures you can see that the hose going to the front of the engine is trying to kink as it makes the bend to run beside the turbo.

High quality piece!

Johnathan T. 5/5 Verified

Willie R. 5/5 Verified

Preston S. 5/5

Fast and professional!

Casey S. 5/5 Verified

Great quality product. Length is perfect 👌. Recommend FullSend for all your performance upgrades

Brett B. 5/5 Verified

It came with no gaskets this item deff needs to be sold with cover gasket as well as the seal for the crank even a plug for the vent or a fitting to hook a tube to the vent. Didn’t come with shit but bolts. Now I got to track everything else down seperatly makes it a pain in the ass. At this point I’d rather have stayed stock

Jacob M. 3/5 Verified

This is an essential upgrade to any Dodge/Ram that’s fighting 68rfe transmission temperature problems. The stock cooler is very insufficient!!

Brock M. 5/5 Verified

AN line came apart on the hose barb with the clamping nut still tight within 2k miles. Almost nuked a brand new transmission before i could get it to the shoulder.

Brian 1/5

send me some stickers nexted time but all good

Levi D. 5/5 Verified

I installed them when I built my transmission. Hoses are good quality but fittings felt kind of cheap. Not a bad kit at all. I’d recommend it to anyone. Substantial trans temp difference after putting them on. My trans runs a lot cooler now that I’ve bypassed the heat exchanger. 2012 ram 2500 with 68rfe. 9/10 would recommend. Just be gentle with the fittings

Max F. 4/5 Verified

Awesome upper coolant pipe. Just what I wanted polished to go with my other parts. Great price and fast shipping. Also entries to possibly win a bad ass Cummins.

Drew P. 5/5 Verified

KINGSPEED parts a well built awesome quality

Paul D. 5/5 Verified

Great replacement transmission line kit for the 4th gen trucks. Other thing I added was heat sock around the lines running by the turbo and down pipe. Also got another transmission by pass block that has removable line adapters, so you can use the AN adapters.

John B. 5/5 Verified

Love the fitment of the catch can and haven’t had any issues yet great product

Austin C. 5/5 Verified

Finally got my valve cover and catch can installed!! I couldnt be happier with the way it looks!

Kyle T. 5/5

I installed this cooler and a few weeks later got into a wreck that was able to damn near total my truck, the frame is bent in 4 places and it shifted my ranch and bumper a foot. This cooler was the only radiator that survived everything else was destroyed and wrapped around the cooler. I called customer support and was able to order new stainless steel brackets and this cooler will live again. I’m very impressed with the quality and strength of this part and would gladly buy it for another truck.

Fritz G. 5/5

Had a confusion on core for the value body. But once figured out the kit can in a week or less. Pretty easy install. Quality is super high and looks amazing.

Tyson W. 5/5

Amazing valve cover!!

Taylor P. 5/5 Verified

Very happy with quality

Jim B. 5/5 Verified

These fit perfect. 2026 Ram 2500. Easy install didnt have to remove anything. Have a drill and rivet tool is all you need. Would definitely buy again

David Y. 5/5 Verified

I love their product. I change them every three oil changes on my 2002 dodge 2500 diesel.

Leroy V. 5/5 Verified

Everything went together good, no problems

Devin E. 5/5 Verified

Points added a nice touch where some crappy plastic ones previously resided. Great fit

Ken S. 5/5 Verified

I buy a lot of parts for you guy for my business. Will be buying more soon. Thank guy keep it up👍👍

Joshua B. 5/5

I love the product. I am just upset that it wasn’t clear it doesn’t come with any hardware. I currently have no clue what barb fittings and hose sizes I need to get for the valve cover to my catch can. I am currently using a hardware store setup as this is my first Cummins and my first quality build of a truck. If there’s anyway you could assist me or point me in the right direction that would be awesome. Aside from that I’ve had nothing but compliments on it, I actually won top 10 truck and SCT x GFP in Nashville a few weeks back. Everyone including myself love the valve cover.

James W. 5/5 Verified

Shifter works slick!

Samuel R. 5/5 Verified

FSD always delivers!! 🤘🏻

Joe M. 5/5 Verified

So Glad I purchased the high output alternator cable along with the high output alternator. Truck runs Great!

Bradley M. 5/5 Verified

Had this thing for just over a month now. My 7.3 had the small housing alternator from factory so I needed to use the spacers. Using the spacers makes the belt slightly harder to get back on so I would recommend going up 1/2" on the belt size. Otherwise I have no issue, powers the truck just fine for the last 1000 miles.
