Went to the J8 cylinder/booster what a difference...

Doing some quick online searches for this, and sites are charging north of $300 for this part number but my local mopar parts store sells it for $215. Quite the markup.

These go out of stock real quick and don't get made until 300 or more are on order so they tend to bet backordered quite a bit according to the Mopar parts rep for the local shop that I take my jeep to. My local shop had an order placed for mine since august and it was backordered until Northridge 4x4 placed an order of like 600 or something like that and then they got made.

Take the story with a grain of salt, but the backorders for it are real on almost every Mopar website out there.

Eeks. Maybe I’ll buy it if it’s in stock. I have to pick up my half door uppers from them today/tomorrow.

Well, your scare tactic worked. I bought it. The site didn’t say if it was in stock or back ordered. This upgrade was going to happen with axle/brake upgrades anyways, so might as well get it now.

Well I just canceled the order. I received an email stating the part doesn’t match the vin I gave them. Which is weird because the website said it’s a match and the acceptable vehicles listed below list a 2014 JKUS, which is what I have. The parts guy said it’s a 3rd party website and they do their own verification. And this is the part number everyone else is selling on their websites.

The only thing that makes me nervous is it is no returns if I attempt an install and who knows when I will get to it, hate to damage it in the garage and can’t return. I will just wait until I start the whole axle project I guess. I’m in no rush, just wanted to save $$. Below is a link to the website/part.

The bigger booster paired with the master will provide more fluid pressure with less pedal travel to help braking.

Just the booster alone will not make to much of a difference over stock.

Ok thanks but this comes with both right?

Thanks for the info. This booster comes with both? Or am I misunderstanding master?
Sorry just trying to make sure I’m getting this correct.

Correct!

The J8 Master comes with both the booster and the master.
