Eibach ERS Platinum 11-Inch Rear Racing Spring, 5.00-Inch Outside Diameter, 200 lb/in Spring Rate

Eibach PLATINUM series race springs are engineered using our proprietary ultra-high tensile strength steel, for the lowest physical weights and maximum spring travel. More Travel / Deflection than Standard Racing Coil Springs

• Redesigned Barrel Spring shape with increased suspension travel and linearity - will replace the XT Barrel counterparts
• Maximum Travel in Combination with Smallest Block Heights
• Ultra-Lightweight for Reduced Unsprung Mass
• Hi-Tensil Platinum Spring Coil Used
• Each Spring Individually Tested

The Eibach ERS Platinum rear racing spring is engineered for motorsports applications that demand maximum suspension travel, reduced unsprung weight, and consistent performance. Part number eibPR1100.500.0200 uses Eibach’s proprietary ultra-high tensile-strength steel to deliver a lightweight racing spring with excellent durability and deflection characteristics.

Its redesigned barrel-spring profile provides increased suspension travel and improved linearity compared with standard racing coil springs. The compact block design helps maximize available travel while maintaining the performance characteristics required for competitive track and racing use. The Platinum spring is designed to replace corresponding Eibach XT Barrel spring applications where increased travel and lower weight are desired.

Every spring is individually tested to help ensure reliable spring-rate consistency and dependable performance. The 200 lb/in rate is suitable for suspension setups requiring controlled support with predictable response. Professional installation and suspension setup are recommended to ensure proper fitment, preload, ride height, and compatibility with the vehicle’s dampers and other chassis components.
