Hello everyone,
Since the 1320 Trim level is designed for Drag Racing, I'm wondering if from the factory it comes with some kind of Differential brace? Same goes with the Hellcats, I wonder if they come with something to eliminate or help eliminate Wheel hop? I heard this is one of the biggest factors in destroying your diff.

I'm learning about the Aftermarket braces and started to think about the 1320

I have a 1320 and not sure if it has a brace. I've been practicing line lock, trans brake, and launch control. Have not experienced wheel hop and have smoked the tires more than once...lol If I knew where the brace in question is located I don't mind taking a look for it.

On the back of the Diff there is 2 mounting bolts. Right behind the diff the frame has 2 pre drilled and possibly threaded holes. In that location would be a pice of metal mounting to the back 2 bolts on the diff and to the frame.
Here is a aftermarket picture.

Definitely no factory diff brace.

There's a couple different designs but they will all look something like this..

No they don't and adding one will void your warranty, last I heard.
Really, I wonder why it would void your warranty if it's design is to help eliminate wheel hop and prevent the rear differential from getting damaged? Maybe this is a non issue or a made up one to sell products?

Nope....... no diff brace on my 1320

I can see how the diff brace is a good idea however.

I can to but if it voids your warranty I don't see much benefit. If your 1320 has no wheel hop issues , I'm wondering if it's a myth or people not know how to properly setup their cars like tire pressure. The correct RPM etc.

read the Notice on all of their braces.

I would not want to have the rear of the differential bolted to the subframe with no bushings unless the front of the housing was bolted in the same way. It seems that bolting it on only one end might allow the case to move in a way that is not allowed for in the design of the case, possibly causing breakage in a different place. Just my opinion, based on what I see on the picture above.

Because it's wasn't designed by FCA or ZF engineers so can't expect them to cover something under warranty that they had no design input on and no idea how it would affect the rear and other components.

Don't see anything obvious, what's it say?

if you click on the one you want there is a disclaimer:

IMPORTANT:

Use of the DIRS and Race Brace may impact the manufacturer's warranty on the differential. Purchaser assumes all responsibility for installation and use.

Does this look made up? :) It's a real issue but mainly on Hellcats and Demon especially the modified ones. The brace was designed to prevent differential case failure. I have the original Per4mance diff brace, it helps a little with wheel hop and hopefully provides some protection from diff failure if I don't lift quick enough. I use it because my car is not warrantied for drag strip use.

Stock Demons & 1320's that break the diff on the dragstrip are covered under warranty but are not covered if a diff brace is added. I think Slidd explained that.

OMG!!!
My Heart would drop out if that happened to me. WOW.
I think people may modify without thinking about the drive train first. Especially if your adding power. The Cars are designed for Stock power and I'm assuming will handle that all day long at the track especially since Dodge basically tells you to head down and make some passes.

Those rear tires void a warranty too.

I am getting a TBA machine differential brace, stall converter, 1 piece drive shaft added this spring. Along with a couple minor exhaust mods., larger diameter mid pipes, hellcat cat back and electric exhaust cut outs.

Exactly. The torque would just go elsewhere. Next part to wear excessively would be the cradle bushings.
