Remote Reservoir Shock Absorbers Explained

A standard foam cell or gas shock is fine for daily driving and light off-road use, but they have limits. When pushed hard over long stretches of rough terrain, these shocks can overheat. Causing aeration, where the oil and gas mix under extreme heat and motion, reducing the shock’s ability to control suspension movement. The result? A harsh, bouncy ride and dangerous handling.

Remote reservoir shocks are designed to solve this issue. By adding an external reservoir, they significantly increase oil capacity. This extra volume keeps fluid temperatures lower, minimises foaming, and ensures consistent damping even after hours of corrugations or high-speed off-road driving. You’ll enjoy better control, improved ride quality, and confidence knowing your suspension won’t fade when you need it most.

There are two main types of remote reservoir shocks. Piggyback style, shown in the image to the left, has the reservoir permanently attached to the shock body, making for a compact and strong design that’s easy to fit in most vehicles. The other type is hose-mounted style, where the reservoir is connected via a flexible high-pressure hose. This option allows the reservoir to be mounted remotely, giving more freedom to position it where there’s space, airflow, or protection from obstacles. Both designs deliver the same benefits, more oil capacity, better cooling, and reduced shock fade, but the choice comes down to available space and vehicle setup.

Do I Really Need Remote Reservoir Shocks?

If you’re touring fully loaded, towing, or tackling long sections of rough outback tracks, the answer is yes. Shock fade at highway speeds with a loaded 4WD isn’t just uncomfortable, it’s unsafe. Remote reservoir shocks are purpose-built to deliver comfort and stability in the harshest conditions.

How Durable Are They?

Built tough, these shocks use high-tensile steel pressure cylinders, corrosion-resistant plating, hard-chromed shafts, and billet-machined components. Internally, advanced piston valving with Teflon-bronze wear bands reduces friction and prevents metal-on-metal contact. Combined with premium-grade racing oil, they’re designed to handle everything from rugged bush tracks to desert crossings.

Can They Be Serviced?

Yes. Superior Engineering’s remote reservoir shocks are fully rebuildable, repairable, and tuneable. Whether it’s replacing seals, revalving for a different ride feel, or a complete service, parts are available individually or in kits. With the right tools and know-how, keeping your shocks in top condition is straightforward, ensuring long service life and customisable performance.
