Spring Rear 16in x 5in x 100# Platinum

The Eibach Spring Rear 16in x 5in x 100# Platinum is a precision-engineered coil spring designed for mechanics and enthusiasts upgrading suspension systems on performance and street vehicles. This rear spring delivers the predictable, linear rate needed to dial in handling characteristics without compromising ride quality. Whether you're building a lowered stance setup, improving cornering control, or replacing worn factory springs, this Platinum Series coil spring provides the foundation for a refined suspension geometry that responds consistently across all driving conditions.

Manufactured from high-quality steel and finished with Eibach's signature platinum powder coat for corrosion resistance and durability, this spring features a 5-inch inner diameter and 100 lb/in spring rate that balances load-carrying capacity with responsive suspension action. The 16-inch length and conventional design integrate seamlessly into rear suspension architectures where proper ride height and damping control are critical. At 5.25 lbs, the spring weight is optimized to minimize unsprung mass while maintaining structural integrity under dynamic stress. The platinum powder coat protects against salt, moisture, and road debris—a critical advantage for long-term reliability in harsh climates or aggressive driving environments.

This rear spring suits drivers and builders seeking OEM-quality replacement springs or those constructing custom suspension packages where rate consistency matters. The 100 lb/in rate works well with modern shock absorbers and strut assemblies, allowing tuning flexibility for street, autocross, or road course applications. Installation requires proper spring compressors and alignment procedures—professional installation is recommended to ensure correct seating and to maintain vehicle safety systems. Verify fitment with your specific vehicle platform before ordering, as suspension geometry varies across manufacturers and model years.
