Eibach Coilover Spring Rear 16in Length x 5in OD

Eibach Platinum Rear Coil Springs – 5.00in OD x 16.00in Length – Ultra-High Tensile Performance

When precision suspension tuning demands the absolute best, Eibach’s Platinum Series Rear Coil Springs (5.00in OD x 16.00in Length) deliver unmatched strength, linearity, and rate consistency. Engineered using Eibach’s proprietary ultra-high tensile steel, these race-grade springs provide superior travel, minimal deflection, and the lowest physical weight of any comparable steel coil spring on the market.

Available in a wide range of rates — 50, 75, 100, 125, 150, 175, and 200 lb/in — this lineup allows tuners, fabricators, and suspension specialists to fine-tune their setup for maximum performance and control across any terrain or racing discipline.

From desert racing to track-day performance builds, the Eibach Platinum Series gives you the same precision, strength, and reliability trusted by world-class teams and OEM performance programs.

Engineered for Strength, Travel, and Repeatability

Eibach Platinum Series springs are not just built — they’re engineered. Every coil is precision cold-wound from high-tensile steel alloy, heat-treated, shot-peened, and pre-set multiple times to eliminate any possibility of sag or rate loss over time.

Key Performance Advantages:

• Ultra-Lightweight Construction: Less unsprung mass for faster suspension response.

• Increased Travel: More usable compression before block height, maximizing control and comfort.

• Block Resistant: Maintains spring height and rate even under extreme compression.

• Consistent Rate Accuracy: Precision manufacturing holds tolerances to within ±1%.

• Corrosion Resistant Finish: Platinum powder coat resists chips, abrasion, and oxidation.

This combination of precision engineering and advanced metallurgy ensures these springs deliver linear response, reduced friction, and consistent performance lap after lap.

Optimized for Coilover and Rear Suspension Systems

The Eibach Platinum 5.00in x 16.00in coil spring design integrates perfectly with high-performance rear suspension setups — from long-travel off-road coilovers to independent rear suspension (IRS) race applications. With rate options from 50 to 200 lb/in, you can build exactly the suspension feel you need.

Applications:

• Desert Racing / Off-Road Trucks: Handles extreme compression and rebound cycles with zero loss of preload.

• UTV / SXS Builds: Ideal for coilover conversions or tuning dual-rate systems for improved stability.

• Track and Circuit Racing: Provides linear, predictable spring behavior under high cornering loads.

• Custom Fabrication Projects: Used in race chassis, hot rods, and custom coilover-equipped builds.

• High-Performance Street Cars: Enhances ride control and chassis balance while maintaining comfort.

With consistent performance across temperatures and load cycles, Eibach springs maintain their shape, rate, and travel long after others fade.

Technical Specifications

Each rate variant is verified under strict quality control standards, ensuring uniform compression, rate accuracy, and fatigue resistance.

Designed for Race-Grade Performance and Reliability

Eibach Platinum springs are manufactured to the same exacting standards used in professional motorsport programs. Each coil undergoes precision grinding, controlled heat treatment, and automated quality inspection. The result: zero-rate fade, perfect dimensional integrity, and unmatched spring longevity.

Manufacturing Highlights:

• Shot-peened surface for increased fatigue strength

• Multi-step heat treatment for molecular stability

• Pre-set under load to prevent settling

• Powder-coated platinum finish for corrosion resistance and professional-grade durability

These steps ensure the spring’s geometry and performance remain consistent, even through repeated compression cycles, temperature changes, and long-term load exposure.

Unmatched Performance in Every Rate

With seven available spring rates, the Eibach Platinum 16-inch lineup covers virtually every tuning scenario:

By offering a comprehensive range of rates under one configuration, Eibach allows tuners and fabricators to achieve perfect balance without compromise.
