Eibach ERS Platinum 11-Inch Rear Racing Spring, 5.00-Inch Outer Diameter, 170 lb/in 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 competition applications that demand maximum suspension travel, consistent performance, and reduced unsprung weight. Featuring Eibach’s proprietary ultra-high tensile-strength steel, this spring delivers a strong performance-to-weight ratio while maintaining the durability required for demanding track use. Its 170 lb/in spring rate provides predictable suspension response and controlled handling when properly matched to the vehicle and suspension setup.

The redesigned barrel spring profile increases suspension travel and improves linearity compared with conventional racing coil springs. The Platinum design is intended to replace comparable Eibach XT barrel spring counterparts while providing maximum travel with minimal block height. This makes it a suitable choice for performance suspension systems where available travel, ride-height control, and low component weight are important considerations.
