Off-Road Independent Coil Suspension

Trailers, Campers & Caravans

Couplemate™ Off-Road Independent Coil Suspension (ICS) is purpose-built for challenging terrain, including sand and dirt roads, rock crawling, and extended corrugation travel. Our engineers have prioritized strength in this design, making it the top choice on the market for upgrading your off-road toy hauler, boat trailer, or work trailer.

Heavy-Duty Coil Springs

Coil springs are popular in off-road trailer independent suspension due to their smoother ride quality, increased strength, and compact design, while also being highly durable. These factors make them well-suited for handling rough Australian terrain.

Couplemate™ ICS shocks are precision-engineered to complement our Independent Suspension, unlocking peak performance.

Dual Shock Absorbers

Dual shocks on Independent Coil Suspension systems improve stability, reduce vibrations, and enhance control, leading to safer and smoother towing. They also extend component lifespan and provide better support for different load requirements and driving conditions.

Your Choice of Brakes

While the Couplemate Independent Suspension is commonly paired with 12″ Electric Drum brakes, we believe in offering you the freedom to choose what suits your needs best.

Every man and their trailer is different. So, whether you need Hydraulic Disc or Electric Drum, 10″ or 12″ brakes, the choice is yours!

Increased Ride Height

Clearance is vital in off-road towing to enable vehicles and trailers to navigate diverse terrains, maintain stability, and prevent damage from obstacles. It ensures proper ground clearance, weight distribution, and maneuverability, enhancing safety and performance in challenging off-road conditions.

Choose from three ride heights with Couplemate™ Suspension for superior control of your ideal trailer.

Better Strength & Durability

Strength relies on rigidity. While many Independent Suspensions rely solely on a bottom frame trailing arm, the Couplemate™ ICS redefines independent suspension by introducing a top frame. This innovative design fortifies the frame, delivering unmatched durability and resilience in the harshest conditions.

With the added emphasis on strength through the top frame, your ICS ensures zero camber movement. This is important, as it prevents premature wear on your inner or outer tyre.

Built from certified Australian steel, you can be confident that your trailer is supported by a robust foundation.

Australian-Made Quality

All Couplemate™ Independent Coil Suspension systems are proudly manufactured in Brisbane, Australia. Every individual component undergoes rigorous Quality Control to ensure that you receive the best product possible.

Frequently Asked Questions

Minimum & Maximum Weight Capacities

Australian Design Rules (ADR) stipulate that your suspension should be rated at least 20% higher than the actual weight you intend to tow. For instance, if your towing load is approximately 2000kg, it is advisable to opt for a suspension system rated at 2250kg.

It’s important to note that the minimum trailer weight requirement for the installation of a Couplemate™ Independent Coil Suspension is 1250kg. This ensures the proper functioning and safety of the suspension system.

Installing on Steel/Aluminium Chassis

The frame of our Independent Suspension system is constructed from high-quality Australian BlueScope steel, ensuring exceptional strength and durability. If you intend to attach it to a steel chassis, welding is the recommended method for secure attachment.

Alternatively, if you are considering an aluminium chassis, bolting the Independent Suspension system is a perfectly viable option. One of our previous Instagram partners achieved excellent results by bolting our Independent Suspension onto their boat trailer chassis, which you can see in this link.

Tyre & Mudguard Clearance

The Couplemate™ Independent Coil Suspension, a type of trailing arm suspension, is renowned for its exceptional performance. We take pride in tailoring each Independent Coil Suspension system to precisely match the requirements of your trailer.

As your suspension progresses to the production stage, our dedicated team will require additional details regarding your rim and tyre specifications, mudguard clearance, and wheel clearance. If you are unsure about these specifications, your designated team member will be available to assist you in determining the most suitable options for your needs.

Maintenance Guide

One significant advantage of opting for an Independent Coil Suspension (ICS) system is its reduced maintenance requirements compared to traditional spring and beam suspensions.

The primary maintenance tasks for the Couplemate™ ICS system include:

  1. Ensuring that the axle nuts and frame nuts are properly tightened.
  2. Lubricating the bushings to keep them adequately greased.
  3. Regularly inspecting and tightening bolts.
  4. Checking the condition of nuts and bolts.
  5. Inspecting the spring coils for any cracks and replacing them as needed.
  6. Verifying the integrity of the welding for any signs of damage or defects.

By addressing these maintenance tasks, you can ensure the continued smooth operation and longevity of the Couplemate™ ICS system while benefiting from its lower maintenance requirements compared to traditional spring and beam suspensions.
