Eibach Platinum Rear Springs – 13.00 in Length | 5.00 in Diameter | 75–225 lbs/in Rates The Eibach Platinum Series Rear Springs set the benchmark for performance coil springs in both motorsport and off-road applications. Built using Eibach’s proprietary ultra-high tensile strength steel, these 13.00-inch rear springs deliver the ideal balance of precision, control, and reliability across a wide range of spring rates — from 75 lbs/in to 225 lbs/in. Whether you’re tuning a long-travel truck, UTV, desert pre-runner, or circle-track race car, these springs are engineered for repeatable performance and uncompromising quality. Each Platinum Series spring is crafted to tight tolerances and individually tested for accuracy, ensuring consistent load response and ride height even under extreme compression cycles. Built for Performance Eibach Platinum Rear Springs are trusted by racers worldwide because they maintain rate consistency and dimensional accuracy lap after lap. The 5.00-inch outer diameter fits most standard coilover setups, making them perfect for multi-rate combinations or fine-tuning suspension balance. From lightweight setups to heavy-duty configurations, Eibach’s metallurgy and precision manufacturing guarantee the spring you install today will perform flawlessly season after season. Key Features Available in multiple spring rates: 75, 100, 125, 150, 175, 200, and 225 lbs/in for complete suspension tuning flexibility. Ultra-lightweight, high-tensile steel construction minimizes unsprung weight without compromising strength. More usable travel and deflection than standard coil springs, offering superior suspension articulation. Block-resistant design prevents coil bind, preserving consistent ride height and load characteristics. Flat-ground ends ensure true parallel seating for improved spring alignment and damping response. Precision rate tolerance within ±2%, maintaining predictable performance through heat cycles and heavy use. Corrosion-resistant finish ensures long-term durability even in harsh off-road conditions.
