Poly Performance Shock Reservoir Mount: Best Low Profile

The Poly Performance mount is designed for builders facing tight spatial constraints where traditional mounting brackets simply won’t fit. Its low-profile architecture keeps the reservoir tucked as close to the chassis as possible, minimizing the chance of debris strike or clearance issues with oversized tires at full lock.

This mount is a game-changer for those fitting long-travel suspension into cramped factory-style wheel wells. It is sleek, unobtrusive, and holds the reservoir with enough tension to survive intense off-road vibration while maintaining a minimal footprint.

If you find yourself struggling to fit your suspension components into a small space, this mount is your best friend. It offers the perfect balance of secure retention and slim geometry, ensuring that your custom setup remains clean and functional.

How to Choose the Right Shock Reservoir Mount

The primary factor in your decision should be the amount of space available on your chassis and the intensity of your off-road activity. For high-speed desert racing, look for reinforced steel mounts that can handle constant oscillation, whereas a rock crawler might prioritize a low-profile mount to prevent damage from proximity to obstacles.

Always consider the material compatibility between your mount and the shock reservoir body to avoid galvanic corrosion or scratching. If you have an aluminum reservoir, consider using a mount with a rubber liner or a plastic/polyurethane construction to prevent metal-on-metal wear.

Lastly, evaluate your fabrication skills before purchasing. If you have access to a welder, weld-on mounts offer the best long-term security, but if you prefer bolt-on simplicity, make sure the clamp mechanism provides enough surface area to grip the tube securely without crushing it.

Ideal Reservoir Placement for Maximum Airflow

Reservoirs rely on airflow to dissipate the heat generated by your shocks during extended use on rough trails. Aim to position them in a location that receives direct, clean air while remaining shielded from direct tire spray or trail debris.

Avoid mounting the reservoir directly behind the engine or near exhaust components, as the radiant heat will degrade the shock oil’s performance. The best location is often on the main chassis rails behind the front wheel, where the reservoir can stay cool while being protected from direct impacts.

When planning your layout, ensure the hose length allows for full suspension travel without kinking or stretching. A reservoir that is poorly placed can fail prematurely, so take the time to route your lines away from sharp edges or moving parts that could cause a puncture.

Weld-On Versus Bolt-On Mounts for Custom Rigs

Weld-on mounts are essentially permanent, offering unmatched strength and a clean appearance that integrates seamlessly with your chassis design. They are the standard for professional-grade builds but require significant fabrication skill and equipment to install correctly.

Bolt-on mounts provide flexibility, allowing you to move or reposition the reservoir during the tuning process. This is invaluable when you are testing different suspension configurations and need to find the “sweet spot” for performance and clearance without having to grind and re-weld your mounts.

Ultimately, the choice depends on your long-term goals for the vehicle. If the design is finalized and you are focused on reliability, weld it on; if you are still experimenting with your setup, stick with a high-quality bolt-on option.

Routine Maintenance Tips to Keep Mounts Secure

Even the most robust mounts can vibrate loose over hundreds of miles of washboard roads. Make a habit of checking your reservoir hardware every time you perform a pre-trip inspection, paying close attention to any signs of movement or chafing on the reservoir body.

If you are using bolt-on mounts, apply a small amount of thread-locker to the fasteners to prevent them from backing out under vibration. Periodically inspect the rubber or plastic inserts within the mounts for signs of dry rot or compression, and replace them immediately if they have lost their grip.

Cleaning the area around your mounts after a muddy or dusty trip is also essential. Accumulated dirt acts as an abrasive, which can wear down the finish of your reservoir and create a gap in the mount, leading to future failure.

Choosing the right reservoir mount is a small but vital step in building a rig that can handle the unpredictability of the outdoors. Focus on durability and placement, keep your gear clean, and you will ensure your suspension system stays reliable for years of adventure.
