Tri-Port Differential Breather Kit
 
A differential breather that actually makes sense. Our Tri-Port Diff Breather system lets you protect your rear diff, front diff, and transfer case all at once, with separate channels for each one.
 
The Tri-Port Diff Breather has three completely independent channels inside. No shared pathways, no cross-contamination. Each drivetrain component gets its own dedicated port and filtration system.
Built Right, Built to Last
 
CNC-Machined Aluminum Body
Machined from 6061 aluminum and black anodized for strength and corrosion resistance. Clean, professional look with no unnecessary markings.
 
Individual Brass Filters
Each port has its own sintered brass filter mounted flush inside. Better filtration without bulky external housings.
 
Push-to-Connect Fittings
Secure, leak-free Parker connections that stay low profile. No threading or tape needed.
 
Complete Kit
Everything you need: 33 feet of Nylon 11 tubing, custom tube controllers, mounting hardware, drilling template, and tube cutter.
 
Why Three Ports Matter
The triangular layout isn't just for looks. It spaces the connections properly for clean tube routing while keeping each system completely separate. Even if you roll over, contamination from one system can't reach another.
 
Protect Everything at Once
No more choosing between your front and rear diffs. Connect all three systems to one breather.
 
Cleaner Installation
The included tube controllers keep your lines organized and professional looking. No messy zip-tie jobs.
