Jeep SRT-8 Brakes

[Dubstep Shep]

Okay guys, I have a crazy plan, but it may just work.

Awhile back I was thinking to myself that it would be pretty cool if the Jeep SRT-8 Grand Cherokee brakes would work on our trucks. If you've never soon those brakes, they're massive.

I suspect that these calipers may bolt on to our truck spindles without any issues. The only problem is that I know the bolt pattern are different, so custom brake rotors would be required with the 5x5.5 pattern. That's not a big deal IMO, especially if the calipers fit.

Worst case scenerio and the calipers don't bolt up, I've been in contact with Michigan Metal Works and they said they could fabricate a custom spindle for me that is guaranteed to fit the Jeep brakes and whatever else I want it to do. I can pick up a set of these calipers for under a grand, so this is a MUCH cheaper option than the Baer or Rotora kits. Additionally I MAY be able to get the rear calipers to work with a little custom work.

Anyways, if any of you guys have the hookup on OEM parts or anything along those lines, I might be in the market for a few items.

ALSO: If you have a set of OEM spindles after you swapped to drop spindles, I WANT THEM!

Someone already was going to do this on the Z forum and had all the parts. He said it wouldn't work without new spindles.

I've been wanting big brakes for a long time. Nothing like GM brakes where a lot of them are interchangeable.

And I don't see a point to swap the rears since there no bigger than the stock , yeah it's a 4 piston caliper, but I think you understand momentum. lol

Ah fudge. Still cheaper than the Baer and Rotora, even with a $1,500 custom set of spindles.

As for the rear, there's the brake bias to consider. Rotor diameter alone doesn't define braking power. But that's not the issue back there, it's the c clips and the parking brake.

Who needs a parking brake

The Jeep brakes are very beefy. Would look tough behind those SRT 22's up front.

I understand that by the rears are not needed. They won't improve stopping, at least being cost effective.

There shouldn't be any issues with brake bias. Doubt it will throw the ABS off.

You are aware you can get the entire front 4 piston SSBC brake kit for 1500 bucks with rotors, right?

Yes they would lol. I'm considering just going to a hydraulic parking brake so I don't even need the normal one. Even better, I can set that up with all four wheels so I can parking brake my front ones as well.

I don't really agree with you here. On a normal vehicle, the bias is about 70/30. It's probably closer to 80/20 on a truck, but what if you're towing? Then it could be 60/40 with all the added weight in the rear.

In the end, bigger calipers tend to bleed heat a lot faster than smaller ones. If you're going to run out of something, it should be horsepower, not braking power.

Yea, but that's no fun!



Right now I can get the Rotora kit, the same one on Unbroken's truck, in a gloss black for 6k. That's several thousand dollars less than it normally goes for. And that's front and rears.

But if I do that, I can say goodbye to anything but my 22s lol.

Personally, I like that the Rotora is a bolt on affair. It's high quality, but also high price. I feel like the Jeep setup will work, but it'll take some work to get it there, especially in the rear. I also think it'll be a lower cost as well.

Right now I have a day or two to decide before that deal on the Rotoras goes away.

.

In the end , bias won't matter with almost the same size rotors in the rear. Not saying don't do, but I feel it's a waste of money for not much of a upgrade.

I would focus on the front. Let me know what you find. Truck brakes good but I hate them tiny rotors/calipers behind my 22s.

 

[Dubstep Shep]

I'm probably going to take a pass on the rotoras. 6k is just too much for brakes IMO.

I'd like to measure a few dimensions on the caliper and call a few brake companies for calipers. I'll see what I can dig up.

anyone ever try fitting the brakes off the SRT-10 Ram's?

It's been done. There's a thread on this forum somewhere.

The fronts are easy enough. You have to swap the SRT-10 Spindle over, which isn't too bad.

I'm still looking into if it's possible to do the rears. The guy that did it had a third gen so he just swapped the entire rear axle.

 

[BlownGP]

The hard part is not the spindle swap. It's finding the brakes themselves.

New, you're looking at at least $700-800 just for the calipers. If anybody has them in stock
Then since you will be running stock 1 piece rotors, there 40+ pounds each. More unsprung weight.

Yep, which is why I'm looking into other options. You're looking at $1,500 easy for the calipers, rotors, pads, and spindles, and that's if you can get a really good deal on all of it.

I just have one question......

Why?

Are you running into stuff?

Another 100 hp eould be kind of fun, but it stops just fine.

 

[CMil527]

DAMN... i know a few of the guys who did the Jeep GC Brembo kits as a direct swap on the Durango R/T's and full set up's ran about $2000 total!

"Stops just fine" LOL. Yea, it stops fine, once.

Stopping multiple times becomes an issue. There's too much heat in repeated stopping for the stock brakes to work.

Think about what Unbroken did with his truck. There's why.

That's two questions.....

Ok, I give up. What did unbroken do that proved his stock brakes inadequate?

He did a bit of canyon carving and road racing type stuff.
