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: 14kg\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.

The rings locate the assembly, quiet micro‑movement, and help keep NVH in check. This design gives you the feedback you want without the drone you don’t. Tolerances are held tight, surface finish is immaculate, and every edge is chamfered for a clean install and that signature HRD fit and finish we’re known for. With our true spherical bushing design, we've eliminated the binding that is often associated with lesser alternatives, ensuring each shift is as smooth as the next.\u003c\/p\u003e\n\u003cp class=\"MsoNormal\"\u003e\u003cb\u003eAn Easy‑to‑Install Must Have\u003c\/b\u003e\u003c\/p\u003e\n\u003cp class=\"MsoNormal\"\u003eAsk around any Honda forum and you’ll learn that cable bushings are one of those small parts that deliver a surprisingly big change to the driving experience.

Featuring a width of 45mm and a height of 90mm, we've designed our \"DRP\" shift knob to provide the perfect shape for consistent shifts time and time again. Inspired by an aesthetic at home in the era of 90s circuit racers, our \"DRP\" shape has been optimized for ease-of-grip as well as to add a touch of extra leverage to your shifts.\u003c\/p\u003e\n\u003cp\u003eIn pursuit of perfection, we spent countless hours adding density to our design without altering the form factor of our \"DRP\" shift knob. This led us to decide on sculpting a deeply machined inner cavity, featuring a strategically placed stainless-steel slug. Yet even that wasn’t enough. A second cavity was machined to accept a stainless-steel threaded liner, adding both mass and long-term durability for drivers who frequently swap knobs. Together, these components create a sublime, weighted momentum, felt instantly in-hand and echoed in the mechanical honesty of each shift.\u003c\/p\u003e\n\u003cp\u003eFeaturing an understated look, the \"DRP\" shift knob is purely about minimalistic performance. Carefully chosen curvature and dimensions, a complex assembly to reach our desired weight, and a silky-smooth bead blast finish. The end result is an object that proves even something as simple as a shift knob can be reimagined when engineered without compromise.\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eKey Features\u003c\/b\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003ePrecision machined from billet 7075-T6 aluminum\u003c\/li\u003e\n\u003cli\u003eAdded stainless-steel components for increased density\u003c\/li\u003e\n\u003cli\u003eWeight of approximately 252 grams for superior shifting feel\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eBead blasted with an extremely fine grit, silky-smooth to touch\u003c\/li\u003e\n\u003cli\u003eAnodized in our signature Apex Silver for a beautiful finish\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eInspired by an era of 90s circuit racers, minimalistic and functional\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HRD","offers":[{"title":"Default Title","offer_id":42200266244190,"sku":"HRD-DRP-02","price":95.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0560\/9485\/1166\/files\/1-780_5258.png?v=1769603929"}],"url":"https:\/\/happyracer.com\/collections\/in-stock-products.oembed?page=2","provider":"HRD","version":"1.0","type":"link"}
