J8 booster talk

[WSS]

Looking for some info on the J8 booster upgrade.

I bought a J8 booster from Jeephut. Full master cylinder and booster kits are hard to find, so i bought just the booster. Can I swap JUST the booster? or is the OE master cylinder different and will not work with the new J8 booster?

Thanks for any input!

I found all this reading:

Matching Components:
The Mopar J8 booster and master cylinder are designed as a pair, with specific dimensions and features that ensure proper functionality when used together.

• Not Compatible with OEM:
  Attempting to use the J8 booster with an OEM master cylinder will likely lead to compatibility issues, improper brake performance, and potentially damage to the components.
  
  Heavy-Duty Application:
  The J8 booster and master cylinder are designed for heavy-duty applications like those found in Jeep models with larger brakes and/or one-ton axles, according to a Northridge4x4.com listing.
  
  
  Performance Upgrade:
  The J8 booster and master cylinder are considered a performance upgrade, providing better pedal feel, more brake bite, and improved braking performance, according to a Reddit post.

Ok I read the questions. Can I buy a replacement master cylinder? Anyone have a breakdown of the parts that are included in the kit?

I found this part number for the master cylinder, the source is 50/50 reliable. My local auto supply cannot find the number.

This is showing as an option. I do have 60’s and 40’s front and back. Says it’s for a 2015 and up, mine is a 2007
