put in the billet heat exchanger and when removing the old trans lines one of the lines bent when loosening nut. Great quality line fits perfectly way better than factory!

Balance the handling of your classic Mustang with QA1’s 0.875” (7/8”) tubular rear sway bar, engineered for 1964–1970 models. Purpose built for QA1 rear coilover conversions and designed to match the performance of QA1’s front sway bars and suspension systems, this rear bar reduces body roll, improves traction, and helps your Mustang corner with confidence. A bolt on upgrade to the QA1 4 link kit for unlocking even more potential. BALANCED HANDLING & STABILITY Adding a rear sway bar is one of the most effective ways to improve cornering performance on a classic Mustang. QA1’s tubular 0.875” sway bar increases roll stiffness at the rear axle, reducing understeer and keeping your car more level in the turns. The result is sharper handling, more predictable grip, and a Mustang that feels planted and controlled. BOLT-ON INSTALLATION This kit is designed for straightforward installation, bolting directly to the QA1 4 link crossmember with no cutting or welding required. It includes polyurethane bushings and heavy-duty mounting hardware for a complete, ready-to-install solution.

Wehrli 15-19 Chevrolet 2500/3500 Front Bumper Valance Filler Panel Kit w/Tow Hooks - Texture Black
Looks way better than stock studs and last longer.
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!

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.

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!
Excellent customer service.. thank you

Great quality product. Length is perfect 👌. Recommend FullSend for all your performance upgrades
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
This is an essential upgrade to any Dodge/Ram that’s fighting 68rfe transmission temperature problems. The stock cooler is very insufficient!!

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.
FSD 2003-2007 Dodge Cummins Stock Replacement Transmission Line Kit Black Braided
send me some stickers nexted time but all good
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

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.

KINGSPEED parts a well built awesome quality
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.

Love the fitment of the catch can and haven’t had any issues yet great product
Finally got my valve cover and catch can installed!! I couldnt be happier with the way it looks!
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.

Amazing valve cover!!
Kingspeed 06-Current Dodge Ram Billet Budget Builder Valve Cover
Very happy with quality
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
I love their product. I change them every three oil changes on my 2002 dodge 2500 diesel.
Everything went together good, no problems
Points added a nice touch where some crappy plastic ones previously resided. Great fit
I buy a lot of parts for you guy for my business. Will be buying more soon. Thank guy keep it up👍👍
Kingspeed 06-Current Dodge Ram Billet Budget Builder Valve Cover
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.
