Spring 16in Coil-Over 3.0in ID Silver

The Spring 16in Coil-Over 3.0in ID Silver from EIBACH is a precision-engineered suspension component designed for builders and enthusiasts seeking adjustable ride height and dampening control. This 16-inch coil-over spring assembly integrates with modern suspension systems to replace factory springs, allowing independent tuning of preload, compression, and rebound characteristics. Whether you're building a track-focused performance vehicle, lowering a street cruiser, or fine-tuning a daily driver, this silver-finished coil-over delivers the adjustability that separates bolt-on upgrades from truly dialed-in suspension geometry.

EIBACH's coil-over design features a 3.0-inch inner diameter (ID) barrel, a critical dimension that determines compatibility with your shock body and affects the spring's load-bearing characteristics and deflection rate. The 16-inch compressed length is engineered to work within standard ride-height ranges while maintaining adequate suspension travel and bump-stop clearance. The silver finish provides corrosion resistance during long-term use, particularly in harsh weather or high-mileage applications. This specific geometry allows mechanics and builders to dial in corner weights independently, adjust ride frequency to match chassis dynamics, and maintain proper spring rates across different driving conditions without compromising structural integrity or longevity.

Installation requires proper suspension knowledge—this is not a direct bolt-and-go component and demands precision alignment, corner-weight balancing, and shock-absorber matching for optimal results. Vehicle-specific mounting brackets and compatible shock bodies must be verified before purchase; many platforms require additional components like perches, ride-height sensors, or custom fabrication. Professional installation is recommended, as improper setup will create handling issues, premature wear, and unsafe load distribution. This coil-over excels in performance-oriented builds where suspension geometry tuning is critical and drivers demand responsive, adjustable handling characteristics.
