Designed for demanding track use, this spring helps race teams and performance drivers optimize handling dynamics by delivering consistent spring behavior lap after lap. Its high-tensile steel construction provides a strong balance of durability, performance, and reduced weight.\u003c\/p\u003e\u003cp\u003eEach Eibach ER Platinum Spring is manufactured to maintain its dimensions and spring rate within exceptionally tight tolerances. The flat-ground end configuration is designed for accurate seating and parallel alignment, supporting predictable suspension operation. Compared with standard racing coil springs, the ERS design provides increased travel and deflection for improved control through changing track conditions and high-load cornering.\u003c\/p\u003e\u003cp\u003eBlock-resistant construction helps prevent permanent loss of spring height, preserving suspension setup consistency over repeated racing sessions. The spring is supplied as an individual rear motorsport spring and is suited for applications requiring a 13-inch spring length and 5.00-inch outside diameter. Confirm spring rate, installed height, and vehicle-specific fitment requirements before installation. This Eibach component is intended for performance and competition use; no specific vehicle fitment data was provided.\u003c\/p\u003e\u003ch3\u003eProduct Specifications and Technical Data\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eBrand: Eibach\u003c\/li\u003e\n\u003cli\u003eProduct Line: ERS Platinum\u003c\/li\u003e\n\u003cli\u003ePart Number: PR1300.500.0125\u003c\/li\u003e\n\u003cli\u003eApplication: Rear racing suspension spring\u003c\/li\u003e\n\u003cli\u003eSpring Length: 13 inches\u003c\/li\u003e\n\u003cli\u003eOutside Diameter: 5.00 inches\u003c\/li\u003e\n\u003cli\u003eEnd Configuration: Flat-ground ends\u003c\/li\u003e\n\u003cli\u003eMaterial: High-tensile steel\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eWhat's Included\u003c\/h3\u003e\u003cul\u003e\u003cli\u003eOne Eibach ERS Platinum rear racing spring\u003c\/li\u003e\u003c\/ul\u003e\u003cp\u003e\u003cb\u003eFeatures:\u003c\/b\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eConsistent Spring Rate: Maintains spring dimensions and rates within tight tolerances for repeatable handling performance lap after lap.\u003c\/li\u003e\n\u003cli\u003eFlat-Ground End Design: Provides a precise spring seating surface with parallel tolerance of plus or minus 1 degree.\u003c\/li\u003e\n\u003cli\u003eIncreased Suspension Travel: Offers more travel and deflection than standard racing coil springs for improved suspension control.\u003c\/li\u003e\n\u003cli\u003eLightweight, Block-Resistant Construction: Uses high-tensile steel to reduce weight while resisting permanent loss of spring height.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cstyle\u003etable.productattributes, .productattributes td { border-bottom: 1px solid #ddd; border-collapse: collapse; padding: 2px; text-align: left; }\u003c\/style\u003e\n\u003ctable class=\"productattributes\"\u003e\n\u003cthead\u003e\u003ctr\u003e\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\u003ctd\u003eAir Freight Prohibited: false\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003ctd\u003eNot Carb Approved: false\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003ctd\u003eLtl Freight Required: false\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003ctd\u003eProp 65: Y\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003ctd\u003ePart Type: automotive\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003ctd\u003eEpa: N\/A\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003ctd\u003eCarb Acknowledgement Required: false\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003ctd\u003eRegular Stock: false\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003ctd\u003eUnits Per Sku: 1\u003c\/td\u003e\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\u003cbr\u003e","brand":"Eibach","offers":[{"title":"Default Title","offer_id":67580812951804,"sku":"PR1300.500.0125","price":169.43,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0641\/6518\/3740\/files\/3441b35a0126edcbb23632bb3bf4319dL_40352f99-1381-4368-90dd-926e0ff4445d.jpg?v=1790402920","url":"https:\/\/diycustoms.store\/products\/eibach-ers-platinum-rear-racing-spring-13-in-length-5-00-in-outside-diameter-part-pr1300-500-0125","provider":"diycustoms.store","version":"1.0","type":"link"}
