ARB Differential Breather Kit – INEOS Grenadier

Protect your Grenadier's driveline from water and pressure damage. This kit relocates the INEOS Grenadier's axle and driveline breathers to a high, protected point in the engine bay — replacing the exposed factory arrangement that can trap pressure and draw in water on deep wading and hard off-road use.

It pairs ARB's proven high-flow breather kit with a Buzz Overland Grenadier-specific relocation bracket, designed and manufactured in-house for a clean, bolt-on fit.

What's included

• ARB high-flow differential breather kit — anodised billet aluminium manifold with a splash-resistant filter, plus fittings and tubing
• Buzz Overland Grenadier relocation bracket — made in-house for a precise, bolt-on fit

Why fit it

• Relocates breathers to a protected engine-bay position, away from water and debris
• High-flow, zero back-pressure / zero-vacuum design lets your driveline equalise pressure as it heats and cools
• Helps keep water out of your axles and driveline when wading
• Protects seals, bearings and gears from pressure-driven oil weeping and contamination
• Bolt-on installation — no cutting or permanent modification

If you take your Grenadier deep into water crossings, ruts or green lanes, the axle and driveline breathers are your first line of defence against water and grit reaching the oil in your diffs and driveline. Relocating them high in the engine bay keeps that protection where it belongs and makes routine checks much easier — a sensible upgrade for anyone who wades, tows or spends real time off-road.
