Fix Factory Vent Failures with Confidence

ARB Differential Breather Kit for INEOS Grenadier

This ARB Differential Breather Kit relocates the INEOS Grenadier’s factory diff vents to the engine bay, eliminating the risk of stuck relief valves and internal pressure buildup. A reliable fix for long term drivetrain protection.

The ARB Differential Breather Kit from Agile Offroad is the solution for one of the most common INEOS Grenadier drivetrain issues—failing factory differential relief valves. These factory vents are prone to sticking closed, which causes pressure to build inside the differential during long drives or temperature changes.

This upgrade moves the breather inlet and outlet to a protected location in the engine bay, ensuring consistent pressure regulation and ventilation. By removing the reliance on the factory valve, this kit safeguards seals, bearings, and gears from stress and internal damage. It is a simple, bolt on upgrade that delivers real peace of mind for anyone who takes their Grenadier off the beaten path.

Solves factory vent valve failure

Prevents pressure buildup in differentials

Reduces risk of internal drivetrain damage

Keeps axle seals and bearings protected

Bolt on design with no permanent modifications

Stop Pressure Before It Becomes a Problem

  • Relocates Differential Breather to the Engine Bay
The factory diff vent on the Grenadier is known to stick closed, allowing internal pressure to rise and strain the system. This breather kit bypasses that weak link entirely by venting through a remote inlet in the engine bay for consistent airflow and balance.

Protect Seals, Bearings, and Gear Life

  • Relieves Excess Differential Pressure

Built to maintain a steady flow of air, this system helps differentials vent properly during long drives, altitude changes, and varying temps. Preventing trapped pressure means less wear on seals, longer bearing life, and better overall drivetrain reliability.
