These are MUCH better designed and manufactured than the factory manifolds. I installed them on my 2014 and they went on perfectly. No more exhaust tick.
Thanks for your comment. At BD, using high-quality components is an essential part of our recipe for success. All our hardware meets or exceeds mechanical properties per ISO fastener standards wherever we procure them. As for the manifolds, those beefcakes are cast and machined in Canada using high silicon ductile iron.
Yes, the amount of thread engagement is the same. However, this is not the problem with these joints. The issue is the clamp length. In this case, the clamp length is the distance from the cylinder head's face to the bottom of the bolt head. By adding a spacer with longer bolts, the clamp length is increased. Thus increasing the toughness of the bolted joint.
@@MarkedPrivate-n9p I'm having trouble seeing what you're seeing... The BD bolts are physically longer, allowing for a spacer to be used, thereby allowing for more unthreaded length to stretch with the heat expansion. The factory bolts have a shorter total length which don't allow for a spacer to be utilized while being fully threaded in. Since the factory bolts can't be used with a spacer, there is less length available for stretching, therefore it's susceptible to overstress and breakage. What am I missing?
I totally understand what he is saying. The longer bolt has more resistance to breakage due to more material doing the same job. Ansd withstanding more vibration.
Just ordered a set cant wait to get them in.
Now just need for the DT models!!
Oh it’s coming. Soon!
I bought it. But lost some bolts. Where can I buy the bolts from bd diesel for ram 1500 2018
2022 jeep Wagoneer e torque?

Thank you!
will they work on the 6.4
Man, didn’t realize my hemi had something on it that said CHINA so big. 😢
Waiting on the DT 2019+ Ram 1500's
Available now!
Is this for the 6.4 hemi in the ram 2500's?
Hi There, This one he is talking about is for the 5.7 HEMI in the 1500-3500 for 2009-2024 Classic (DS) Body Style Trucks
@BDDieselPerformance but is there the same issue with the 6.4 hemi? If so do you have the replacement headers for them or know where i can get them?
How do I order
You can order online here - us.bddiesel.com/products/exhaust-manifold-kit-dodge-ram-5-7l-hemi-1500-2500-3500-2009-2022?variant=41740061442231
Best manifolds in the market. 100 times better than even OE. My hemi tick is GONE. 🎉 🎉
Did you torque the bolts or just with hand
@@gruposuperefectivo456 yes I torqued. Torque wrench is only $50
I assume they are still holding up after a few months?
why are the bolts made in china? Is the Manifold also made in China as well?

If you have to use a spacer for bolt, its not any longer then. You lost some creditability. Compare both with spacer. Same length.

@@BDDieselPerformance But the video references the length and even shows it. Thus implies what I said.

@@4thdimensiontravels855 But is it longer?
