Eibach Coilover Spring 20in Length x 5in OD

Eibach Platinum Rear Coil Springs – 5.00in OD x 20.00in Length – Premium Ultra-High Tensile Steel

The Eibach Platinum Series Rear Coil Springs (5.00in OD x 20.00in Length) represent the pinnacle of precision-engineered suspension performance. Built using Eibach’s proprietary ultra-high tensile steel, these springs deliver unmatched strength, minimal deflection, and consistent performance across a wide range of racing and performance applications.

Available in multiple rates — 70 lb/in, 85 lb/in, and 100 lb/in — each spring is engineered for optimal travel, block resistance, and weight reduction without compromising reliability. Whether you’re building a desert race truck, fine-tuning your coilover suspension, or refining a performance chassis, Eibach Platinum Springs provide the accuracy and consistency required for championship-level results.

Engineered for Strength, Travel, and Weight Efficiency

Eibach’s Platinum Series springs redefine what’s possible with high-tensile steel. Through advanced material processing and precision winding technology, each spring achieves superior travel and load control while maintaining tight rate tolerances — typically within ±1%.

Key Engineering Advantages:

• Ultra-Lightweight Construction: Eibach’s proprietary steel alloy reduces unsprung weight for faster suspension response.

• Maximum Travel: Extended stroke capability ensures greater suspension articulation and control.

• Block Resistance: Designed to eliminate coil bind and maintain full spring function at maximum compression.

• Precision Manufacturing: Ground flat ends and laser-verified diameter control ensure concentricity and consistent fitment.

The result is a spring that remains linear, predictable, and repeatable — no sag, no loss of rate, and no performance fade even under continuous race abuse.

Designed for Professional Suspension Systems

The Eibach 5.00” OD Platinum Series coil springs are ideal for rear suspension applications across multiple disciplines. From long-travel off-road vehicles to road race cars, they provide the foundation for balanced, responsive suspension geometry.

Optimized For:

• Off-Road Racing & Desert Applications: Handles intense articulation and variable load conditions.

• Track & Time Attack Vehicles: Offers predictable balance under heavy braking and corner loads.

• UTVs & Custom Performance Builds: Perfect for coilover conversions and chassis tuning projects.

• High-Performance Street Builds: Enhances control and comfort without sacrificing ride quality.

Eibach’s Platinum Series springs integrate seamlessly with high-end dampers such as FOX, KING, and Ohlins, providing a professional-grade suspension solution ready for any environment.

Technical Specifications

Each spring undergoes a multi-stage quality inspection, including rate verification, dimensional analysis, and surface finish testing. That’s why Eibach’s rate accuracy and repeatability are unmatched in the industry.

Precision Fit and Manufacturing Quality

Each Eibach Platinum Spring is ground to precise tolerances, ensuring both ends are perfectly parallel for uniform load distribution. The high-tensile wire is heat-treated, shot-peened, and pre-set multiple times to maintain rate consistency and prevent sag — even after thousands of compression cycles.

Manufacturing Highlights:

• Precision cold-wound for exact coil pitch and spacing

• Shot-peened surface for enhanced fatigue life

• Powder-coated platinum finish for corrosion resistance

• Rate-tested and verified under ISO-certified standards

Unlike generic springs, Eibach’s production process guarantees long-term stability — meaning the rate you install is the rate you’ll have, season after season.

Consistent Performance from Lap One to the Finish Line

Eibach Platinum Springs are trusted by professional teams in rally, short-course off-road, and circuit racing alike. Their ability to retain rate and dimension through heat cycles, vibration, and impact loads sets them apart from conventional coil springs.

Performance Benefits:

• Linear compression characteristics for predictable handling

• Tight rate tolerance within ±1%

• Reduced coil mass for faster suspension response

• Superior fatigue resistance — no spring fade or sag

With consistent rebound and compression behavior, these springs make suspension tuning more predictable, allowing precise adjustments to damping, preload, and balance.

The Platinum Advantage: Race-Proven Innovation

Eibach’s Platinum line is the result of decades of suspension engineering leadership. Their proprietary steel alloy, advanced manufacturing, and industry-leading quality control combine to create one of the most efficient spring designs ever produced.

• More Travel per Inch of Height: Compared to conventional steel springs, Platinum Series coils allow greater usable stroke within the same physical dimensions.

• Flat-Ground End Configuration: Ensures optimal seat contact for uniform load transfer.

• No Rate Loss: Resists fatigue and maintains its specified rate throughout the spring’s lifespan.

• Premium Finish: The platinum powder coating resists rust and complements high-end builds visually and functionally.

This combination of technology and craftsmanship makes the Platinum Series the gold standard for high-performance suspension builders worldwide.

Application Examples

• Desert Race Trucks & Pre-Runners: Maximizes suspension travel and shock performance in extreme terrain.

• UTVs / SXS: Provides lightweight spring control for coilover conversions and ride height tuning.

• Track Cars / Time Attack Builds: Maintains consistent damping behavior through repeated high-load cornering.

• Custom Street Rods & Fabrication Projects: Perfect for builders demanding both strength and aesthetics.

These springs are ideal for performance-driven builders who value precision as much as performance.
