Diff Breathers
BOSS Diff Breather Kits protect your drivetrain from water and dust by relocating factory breathers to a safer, higher position. Essential for 4WDs and touring rigs, they prevent contamination and pressure build-up that can cause costly damage.
Why fit a BOSS Diff Breather Kit?
- Water protection – keeps diffs, gearbox, and transfer case safe during creek crossings and wet conditions.
- Improved reliability – reduces the chance of costly repairs from contaminated oil or blown seals.
- Heavy-duty components – quality fittings, hose, and filters designed for long-term durability.
- Easy installation – complete kits with everything needed for a clean, factory-style fit.
Applications
Perfect for 4WDs, touring rigs, and work vehicles that regularly encounter water, mud, or dust. A BOSS Diff Breather Kit is an essential upgrade for any off-road setup, giving you peace of mind that your driveline is properly protected wherever you travel.
