Digressive valving provides higher damping force at low piston speeds. This improves control during low-speed events such as cornering, braking, and acceleration, allowing for better vehicle stability and handling.\u003c\/p\u003e\n\u003cp\u003eAt higher piston speeds, the damping force levels off, allowing for softer reactions to bumps, potholes, and other road imperfections. This ensures that the ride remains both comfortable and refined while maintaining excellent tire contact with the road for improved grip.\u003c\/p\u003e\n\u003cp\u003eThis technology has allowed HRD to create a suspension system that feels balanced and predictable under all conditions.

This configuration dissipates heat more effectively, ensuring consistent damping performance during prolonged or intense use, such as extended track days.\u003c\/p\u003e\n\u003cp\u003eOur monotube design accommodates a larger piston, allowing for more precise and consistent damping control across the entire valving curve. This enhances the overall effectiveness of the suspension system, making it more responsive to both low-speed and high-speed events.\u003c\/p\u003e\n\u003cp\u003eMonotube Coilovers are constructed with a single, larger-diameter tube, which is inherently stronger and more durable than alternatives such as twin-tube designs.

The electric current evenly deposits the coating onto the component’s surface, even reaching intricate crevices and hard-to-coat areas. Once applied, the coating is baked to create a durable, uniform finish that is highly resistant to corrosion, chipping, and wear. For coilovers, which are often exposed to harsh conditions such as road salts, debris, and moisture, EDP coating provides exceptional longevity and maintains both structural integrity and aesthetics.\u003c\/p\u003e\n\u003cp\u003eCompared to alternative options like powder coating or zinc plating, EDP coating offers superior uniformity and coverage. Powder coating, while durable, can sometimes leave small gaps or uneven finishes in hard-to-reach areas, leading to potential corrosion vulnerabilities. Zinc plating, on the other hand, provides basic corrosion resistance but lacks the robustness and longevity of EDP coating, especially under extreme environmental stress. EDP coating helps ensure that your Coilovers maintain their appearance and functionality for years without premature wear even in adverse climates.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eSwift Springs Standard\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eSwift Springs are celebrated as the pinnacle of suspension technology, thanks to their unique combination of material science and innovative engineering. The foundation of their superiority lies in their proprietary steel alloy, HS5.TW, which is lighter and more resilient than the silicon chrome steel alloys used by most competing spring manufactures. This also allows Swift to use less coils per inch on their springs, reducing unsprung weight from your suspension.\u003c\/p\u003e\n\u003cp\u003eOne of the defining characteristics of Swift Springs is their linear spring rate, which ensures consistent performance throughout the spring's compression range. This feature not only improves tire grip but also reduces unnecessary suspension movement, providing a predictable and stable driving experience.

Electrophoretic deposition (EDP coating) is used on all of our shock bodies to further increase the longevity of our Coilovers in adverse climates.\u003c\/p\u003e\n\u003cp\u003eAll of our off-the-shelf kits feature spring rates that have been meticulously selected by taking into account shock travel, motion ratios, and harmonic frequencies transmitted from the road into the cabin during street and track use. We've intentionally selected spring rates that are appropriate for each chassis, giving a balanced and refined driving experience that inspires confidence without the need to overspring our suspension.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDual Duty Digressive Damper™\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eEach set of suspension from HRD features a monotube design utilizing our Dual Duty Digressive Damper™ technology. Digressive valving provides higher damping force at low piston speeds. This improves control during low-speed events such as cornering, braking, and acceleration, allowing for better vehicle stability and handling.\u003c\/p\u003e\n\u003cp\u003eAt higher piston speeds, the damping force levels off, allowing for softer reactions to bumps, potholes, and other road imperfections. This ensures that the ride remains both comfortable and refined while maintaining excellent tire contact with the road for improved grip.\u003c\/p\u003e\n\u003cp\u003eThis technology has allowed HRD to create a suspension system that feels balanced and predictable under all conditions. It provides the stiffness needed for precise handling during performance driving and the refinement required for everyday road conditions.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eMonotube Construction\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eHRD's monotube damper design separates the damping oil and gas chamber with a floating piston. This configuration dissipates heat more effectively, ensuring consistent damping performance during prolonged or intense use, such as extended track days.\u003c\/p\u003e\n\u003cp\u003eOur monotube design accommodates a larger piston, allowing for more precise and consistent damping control across the entire valving curve. This enhances the overall effectiveness of the suspension system, making it more responsive to both low-speed and high-speed events.\u003c\/p\u003e\n\u003cp\u003eMonotube Coilovers are constructed with a single, larger-diameter tube, which is inherently stronger and more durable than alternatives such as twin-tube designs. This makes them ideal for high-performance applications where durability and reliability is paramount.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eElectrophoretic Deposition (EDP) Coating\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThis advanced coating method involves submerging components in an electrically charged bath containing epoxy or acrylic resins. The electric current evenly deposits the coating onto the component’s surface, even reaching intricate crevices and hard-to-coat areas. Once applied, the coating is baked to create a durable, uniform finish that is highly resistant to corrosion, chipping, and wear. For coilovers, which are often exposed to harsh conditions such as road salts, debris, and moisture, EDP coating provides exceptional longevity and maintains both structural integrity and aesthetics.\u003c\/p\u003e\n\u003cp\u003eCompared to alternative options like powder coating or zinc plating, EDP coating offers superior uniformity and coverage. Powder coating, while durable, can sometimes leave small gaps or uneven finishes in hard-to-reach areas, leading to potential corrosion vulnerabilities. Zinc plating, on the other hand, provides basic corrosion resistance but lacks the robustness and longevity of EDP coating, especially under extreme environmental stress. EDP coating helps ensure that your Coilovers maintain their appearance and functionality for years without premature wear even in adverse climates.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eSwift Springs Standard\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eSwift Springs are celebrated as the pinnacle of suspension technology, thanks to their unique combination of material science and innovative engineering. The foundation of their superiority lies in their proprietary steel alloy, HS5.TW, which is lighter and more resilient than the silicon chrome steel alloys used by most competing spring manufactures. This also allows Swift to use less coils per inch on their springs, reducing unsprung weight from your suspension.\u003c\/p\u003e\n\u003cp\u003eOne of the defining characteristics of Swift Springs is their linear spring rate, which ensures consistent performance throughout the spring's compression range. This feature not only improves tire grip but also reduces unnecessary suspension movement, providing a predictable and stable driving experience. Additionally, Swift Springs exhibit minimal coil binding and harmonic vibration, which are common issues with alternative springs, ensuring long-term durability and comfort.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFeatures\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e15 Way Adjustable Compression and Rebound\u003c\/li\u003e\n\u003cli\u003eDual Duty Digressive Damper™ Technology\u003c\/li\u003e\n\u003cli\u003eProprietary Stainless Steel Pillowball Bearings\u003c\/li\u003e\n\u003cli\u003eTitanium Hardware on Studs, Nuts, and Pillowball Collars\u003c\/li\u003e\n\u003cli\u003eTitanium Damping Adjustment Knobs\u003c\/li\u003e\n\u003cli\u003eSwift Springs Standard on all HRD Street Performance Coilovers\u003c\/li\u003e\n\u003cli\u003eAnodized Aluminum T6 6061 Camber Plates and Mounts\u003c\/li\u003e\n\u003cli\u003eMonotube Damper with High Pressure Nitrogen\u003c\/li\u003e\n\u003cli\u003eFront Spring Rate: 7kg \/ Rear Spring Rate: 11kg\u003c\/li\u003e\n\u003cli\u003eDurable Anodized 7075 Aluminum Spanner Wrenches\u003c\/li\u003e\n\u003cli\u003eAll-Weather EDP Coating on Shock Bodies\u003c\/li\u003e\n\u003cli\u003eAssembled in the United States\u003c\/li\u003e\n\u003cli\u003e5 Year Limited Manufacture's Warranty\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eTrack Ready, Daily Approved\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eOur Street Performance Coilovers were designed from the ground up for the enthusiast seeking a refined and composed ride on the street that simultaneously inspires confidence when pushed to the limits.
