@freebird_78 great feedback with the powerstop. I donít care much of brake dust but to me itís very minimal on my Jk with the crown. Something to consider when I upgrade the pads. Thanks again.

EXCEPT... the pads that come with this kit are one of the dirtiest, dustiest pads I've ever seen. And that's saying a lot, considering I have a Charger SRT with the 6 piston Brembos. Those Brembo pads literally dusted the wheels just going around the block.

I solved the JK's dirty brakes the same way I fixed the Charger's. PowerStop Z36 carbon-ceramic pads. They are, effectively, dustless. On the Charger, I lost a tiny bit of bite compared to the super aggressive Brembo pads.

On the JK, I actually picked up quite a bit of bite. The difference in stopping power between the pads that come with the Crown kit and the PowerStop Z36s is about the difference in stopping power between the OEM brakes and the Crown BBK. Yes, that much difference. Of course, you HAVE to bed the pads in as PowerStop describes. You leave quite a bit on the table if you skip their bedding process. For $40, it's a no-brainer for me.

Do you happen to have the part number for the pads you used from Powerstop ?

I had this same problem when removing my booster.





There are 2 ways to solve this problem.
1. Take a 13mm deep well socket and grind down the side of it.
2. Undo the 4 bolts inside the engine bay instead.


For #2, the booster attaches to a mounting plate as an assembly. So if you remove the 4 bolts in the engine bay side, you remove the booster from the mounting plate. If you remove those 4 bolts under the dash, then you're removing the mounting plate and the booster combined assembly.


You reuse the mounting plate with the new booster, so disassembly either way will work.

I created and posted this a few pages back. This is a list of replacement pads including the PowerStop pads. You will notice a common 1084 number across brands.

Unfortunately we don't offer a JK BBK with a 5x5.5" rotor.

These are still in our testing phase so they're still a ways away from being available for purchase. When they are available we will create a Facebook & Instagram post. Keep your eyes peeled!

Question Replace brake lines too?

When we installed our BBK on our 2015 JK we used the Crown Performance (different company like Quadratec stated prior) brake lines that were included in the lift kit we used and didn't run into any fitment issues. See the image below for the orientation of our brake hoses.


As mentioned back a year ago, unlike the Mopar BBK, the Crown BBK doesn't come with new/replacement brake lines for the front.


As noted above, that isn't so much as new brakes lines aren't needed, but rather based on the assumption that Crown BBK customers have already replaced their brake lines and don't need a new set.


I am just wondering, how many of you who installed the Crown BBK, and don't have lift, are still using your original factory brake lines? Or did you also swap to ones like those included with the Mopar BBK (68184808AC, 68184809AC)?

I have a 2 1/2" lift, but I'm running stock brake lines with drop brackets. The stock lines worked fine for me with Crown kit.


I do have a set of extended lines ordered, but they are backordered. They should be here in a week or two unless the backorder date gets bumped.

This is a great kit. I have a 2.5" Metalcloak lift with their brake lines. I used the Teraflex brake line brackets to stabilize the lines behind the shocks. I thought there was a big improvement with just the kit, but a couple of months later, my Mopar booster and master cylinder arrived. I'd ordered it at the same time as the Crown kit. After installing, I couldn't be happier with the combo. Last week in western Colorado, three deer jumped out of the ditch, right in front of me. I was doing about 45 with my little trailer behind, and jumped on the brakes. The Jeep stopped like it was on Velcro. I'm not sure I could have got shut down with the oem setup. The "touch" of the brakes when just coming up to a stoplight is so much improved. This should have been the factory setup.

We're now going to offer our RT Off-Road Big Brake Kit (RT31046) in 3 boxes instead of 2. We're also going to re-organize the boxes and add more bubble to the boxes so nothing has the opportunity to move around.


Its been just over a year since this post with info from Adam. I thought I would follow-up to it with my experience.


I just got my RT Off-Road Big Brake Kit (RT31046), drop shipped from Marshfield, MA, and it came in just two boxes. Both look OK on the outside (haven't torn them apart yet). Here is a pic of the boxes. You can see that their labels even show "1 of 2" (1/2) and "2 of 2" (2/2).

@WaltA mine and several initial users had poor packaging. Yours looks upgraded as mine came in a generic box with no logos besides a couple Of QT vendor stickers.

Yes, I am pleased with the packaging. I have since opened up the two boxes, and the contents appears to be all fine.


I guess the real purpose of my post was to counter (update, correct) the impression meandering thru here that "two boxes = bad", "three boxes = good". As in my case, two boxes can still be good.

This is my Christmas present from Santa. So, technically, I should not be even opening it quite yet.


Also, I am unsure yet if I will buy the brake lines, and the master cylinder/ booster, too. If I did, I would want to change all at the same time. Any suggestions?

The master cylinder and booster helped the feel of the brake pedal tremendously for me, but I've got a 2011. Not sure exactly when the OEM master cylinder was upgraded.

I recommend the master cylinder/Booster combo as well. As you have just increased the system fluid capacity by 50% with the dual piston calipers, the original master cylinder is not designed for the additional capacity. It works but I'm not taking chances with my brakes. It's a small investment (less than $300) to ensure the system is engineered correctly. I have a nice , firm pedal with this combination and my 37's stop on a dime. The larger booster has enough force behind it to drive the larger master cylinder.

You probably don't need brake lines unless you are lifted and haven't already done something with the stock ones. I changed mine out because I was at 3.25" lift and also thought I had blown one initially so I ordered braided steel replacements prior to doing any real troubleshooting.

I run the BBK with a crown oversized MC but without the Booster. I still feel that the booster will be a future purchase. I am not 100% satisfied with the current setup. I would recommend the booster and MC be installed with the BBK.

For the record, I did the calipers and rotors one weekend, then drove it for a week before doing the master cylinder and booster. Before the mc/booster was installed, the Jeep stopped fine, but you had to push the pedal way down to get it fully engaged.


With the upgraded Mopar mc/booster, the brakes are pretty much fully engaged with the pedal only half way to the floor. It's nice and firm. It actually took a few minutes to get used to the pedal being so responsive.

@Prages ... i had the BBK installed for a week as well before getting the Mopar MC/BB upgrade. Initially bled incorrectly and pedal was all the way to the floor. I then manually bled the system again and my pedal effort was just like stock with more brake power.

Adding the Mopar MC/BB was a great upgrade.

So my front rotors are warped. Any idea on the Centric part number for replacements? I'd rather go with a name brand than the who knows version that came with the Mopar kit.

Late 2012+ Ram 1500 rotors are what you need for either the Mopar or Crown BBK.

Pretty sure the ram rotor is a different lug pattern. I would get an oem rotor. I have had best luck with them. One of these older threads has the part number, try and cross reference if you want a different brand.

4 Wheel Parts has the Crown BBK on sale today for $360 as part of their 12 days of Christmas. I would not hesitate to get this today if you are thinking about it.

The Ram is a 5x5.5". An OEM rotor will NOT work with this kit as the diameter is much smaller on OEM compared to what the kit has. This uses 2012+ Ram 1500 rotors and calipers/pads.



EDIT: Shit im all screwed up here...Somewhere a few pages back is the part numbers needed.

Are the rotors specific to this kit or are they the same as an existing OEM component?
