Eibach ERS Platinum 14-Inch Rear Racing Spring, 3.50-Inch Outside Diameter, 85 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

• 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!

Brief Description: The Eibach ERS Platinum rear racing spring is engineered for competitive motorsports applications that demand consistent performance, reduced unsprung weight, and reliable spring behavior under repeated loads. This Eibach Platinum series spring uses proprietary ultra-high tensile strength steel to provide greater travel and deflection than standard racing coil springs while maintaining precise dimensions and spring rates lap after lap.

Key Product Specifications & Technical Data:

• Brand: Eibach
• Series: ERS Platinum
• Part Number: P1400.350.0085
• Application: Rear racing suspension spring
• Spring Rate: 85 lb/in
• Free Length: 14 inches
• Outside Diameter: 3.50 inches
• End Configuration: Flat-ground ends with parallel tolerance within +/-1 degree

The flat-ground end configuration promotes consistent seating and predictable suspension operation. Its ultra-lightweight construction helps reduce overall spring mass without compromising the durability required for demanding race conditions. The spring is also designed to resist block setting, helping it retain its installed height and specified rate over extended use.

What's Included: One Eibach ERS Platinum rear racing spring. This product is intended for automotive racing and performance suspension applications; vehicle-specific fitment should be confirmed before installation. Professional setup and suspension tuning are recommended to ensure the spring rate and configuration are appropriate for the vehicle, damper, and intended track use.

Fitment: Universal motorsports suspension component. Specific vehicle fitment data was not provided. Verify application requirements, spring dimensions, rate, and suspension compatibility before purchase. This product may contain chemicals known to the State of California to cause cancer or reproductive harm.

Features:

• Ultra-high tensile strength steel: Reduces physical spring weight while supporting greater travel and deflection than standard racing coil springs.
• Consistent dimensions and spring rate: Maintains precise performance tolerances through repeated laps and race events.
• Flat-ground end configuration: Provides a stable, predictable seating surface with parallel tolerance within +/-1 degree.
• Block-resistant construction: Helps prevent permanent height loss and preserves suspension setup consistency.
