Eibach ERS Platinum 16-Inch Rear Racing Spring, 3.50-Inch Outside Diameter, 115 lb/in – P1600.350.0115

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

• The Eibach ER Platinum Springs will Maintain Their Dimensions and Rates to Incredibly Tight Tolerances, Lap after Lap, Race after Race
• Flat-Ground End Configuration with Parallel Tolerance to +/-1 Degree
• Ultra Light-Weight Using High Tensile Steel
• Block Resistant - No Loss in Spring Height!

The Eibach ERS Platinum P1600.350.0115 rear racing spring is engineered for competition vehicles that demand consistent performance, reduced unsprung weight, and extended spring travel. Made from Eibach’s proprietary ultra-high tensile strength steel, this spring delivers a lightweight design while maintaining the durability and precision required for demanding track use.

Compared with standard racing coil springs, the Eibach Platinum series provides greater travel and deflection to help maintain vehicle control over varied racing surfaces. The spring is designed to retain its dimensions and 115 lb/in rate within exceptionally tight tolerances, lap after lap and race after race. Its flat-ground end configuration supports accurate installation and consistent load distribution, while the block-resistant construction helps prevent loss of spring height during repeated compression cycles.
