All-Terrain Vehicles (ATVs) are popular for both recreation and practical work. A good suspension system is necessary for a comfortable and controlled ride. Among the suspension components, springs play a key role. This article will help you choose the right springs for your ATV by discussing different spring types, load capacities, and terrain considerations.
Understanding the Role and Types of ATV Suspension Springs
ATV suspension springs absorb shocks from uneven terrains, ensuring a smoother and safer ride. They come in several types: coil springs, leaf springs, and air springs.
Coil Springs are durable and consistent, commonly used due to their balance of performance and cost. For example, a trail-riding ATV might use coil springs to handle moderate off-road conditions effectively without incurring high costs. The material composition and heat treatment of the coil spring also contribute to its resilience and longevity.
Leaf Springs provide excellent load distribution and can support heavier weights but are generally stiffer. They are suitable for utility ATVs that carry heavy loads or tow equipment, benefiting from the stability these springs provide. Their stiffness can be a downside for ride comfort, but they excel in scenarios demanding higher load capacities.
Air Springs offer adjustable load support and improved ride smoothness but require additional maintenance and cost more. These are often used in high-performance or competition ATVs where the ability to fine-tune suspension stiffness is important for achieving optimal handling in diverse conditions. The need for periodic checks and adjustments can be a limitation for casual users.
Understanding these types is important, as choosing the right one can impact your ATV's performance and longevity. For example, selecting air springs for an ATV that primarily operates in rugged, remote areas may not be ideal due to the potential maintenance challenges.
Critical Factors to Consider in Spring Selection
-
Spring Rate: The rate determines how much load the spring can support. Select a spring rate suitable for your rider weight and typical load. If the rider weighs 180 lbs and carries an additional 50 lbs of gear, choose a spring rate that can handle the combined weight of 230 lbs.
-
Material: The choice of material impacts durability and performance. Steel and alloys offer good strength. Consider corrosion resistance for longevity, as stainless steel provides resistance to rust, which is beneficial for ATVs used in wet or muddy environments.
-
Suspension Type Compatibility: Ensure the selected spring is compatible with your ATV's suspension configuration. Different suspension systems, like dual A-arm or swingarm, may require specific spring types and sizes.
-
Load Capacity: The spring should support the combined weight of the rider and any additional cargo. For example, if a rider and cargo together weigh 250 lbs, select a spring with at least 250 lbs load capacity for proper performance.
-
Environmental Factors: Consider the typical riding conditions. Mud, sand, and water exposure require springs with corrosion resistance. In coastal areas where saltwater exposure is common, a spring with a protective coating or made from a corrosion-resistant alloy is advisable.
-
Budget: Balance cost with performance benefits. Higher-grade materials and specialized designs like air springs cost more. If you frequently ride in harsh conditions, investing in a good-quality spring can save money over time by reducing the need for frequent replacements.

-
Factory Connection: Offers both pre-made and custom springs. Custom springs are designed to match specific rider weights and styles, enhancing performance. Understanding the rider's specific needs can help in achieving optimal results.
-
Hyperco: Hyperco provides lightweight but strong springs with high endurance limits, suitable for long-term use under demanding conditions. These springs perform consistently over time due to their manufacturing process, although the lightweight design may reduce comfort in low-impact conditions.
Guidelines for Spring Installation and Maintenance
Installing new springs on your ATV suspension involves several steps to ensure performance and safety. First, gather all necessary tools, including a spring compressor if working with coil springs. Elevate the ATV using a lift or jack stands and remove the existing springs by unbolting the suspension components. Be careful during this step, as improper support may result in injury. Install the new springs, ensuring they are properly seated in their mounts. Torque all fasteners to the manufacturer's specifications. For example, using 50 ft-lbs as specified prevents loosening or damage to the threads.
Regular maintenance includes periodically checking for wear such as cracks, deformation, or rust on the springs. Lubricate any moving parts connected to the springs and keep the area clean to prevent debris buildup. Note that stainless steel springs require less maintenance than traditional steel springs due to higher corrosion resistance. Adjusting the suspension settings based on the load and riding conditions extends the life of your springs. For example, frequently adjusting pre-load settings and damping when switching between solo rides and carrying heavy loads balances performance and durability.
Common Mistakes and FAQs in ATV Suspension Spring Selection
Ignoring Spring Rate: Selecting a spring with an incorrect rate can lead to poor handling and ride quality. For instance, a high spring rate in an ATV intended for off-road use can cause a stiff ride, reducing traction on rough terrain.
Overlooking Material Quality: Low-quality materials may be cheaper but often lead to premature wear and failure. Materials like chrome-silicon and stainless steel offer better durability and performance, necessary for ATVs used in extreme conditions.
Improper Installation: Not following torque specifications or failing to seat the spring correctly can cause handling issues and potential damage. Proper installation ensures that the springs perform as intended, maintaining both safety and performance standards.
Neglecting Compatibility: Using a spring incompatible with your suspension system can lead to performance issues. Always check the manufacturer's specifications to ensure the spring matches the shock absorber and suspension geometry of your ATV.
Not Adjusting for Load: Failing to consider the weight of the rider and cargo can result in suboptimal spring performance. Adjusting the spring rate according to the total anticipated load improves ride quality and handling. For example, if you often carry heavy gear or ride with a passenger, selecting a spring with a higher load capacity is necessary.
FAQs:
Can I mix different types of springs in my ATV suspension? It is generally not recommended as it can lead to uneven performance and handling issues. Consistency in spring types ensures uniform behavior and reduces the chances of unbalanced suspension dynamics.
How often should I replace my ATV suspension springs? Regularly inspect springs for wear and replace them if any signs of damage are found or as recommended by the manufacturer. For example, if the spring has visible corrosion or has been deformed, replace it immediately.
Is a higher spring rate always better? Not necessarily. A high spring rate might make the ride stiff and uncomfortable. Select a rate suited to your specific needs. For instance, a high spring rate can be beneficial for racing ATVs requiring sharp, responsive handling but not ideal for recreational off-road ATVs where comfort and traction are more important.
Conclusion
Selecting the right springs for your ATV suspension requires careful consideration of several factors, including spring rate, material, and compatibility with your current system. This decision impacts the comfort and safety of your ride as well as the performance of your ATV. By understanding the types of springs available, comparing different brands, and following proper installation and maintenance guidelines, you can improve your ATV's performance. Focus on these factors and regularly assess the condition of your springs for better riding experiences.
