Spring Rear 20in x 5in x 100#

The Spring Rear 20in x 5in x 100# from EIBACH is a precision-engineered coil spring designed for vehicle suspension tuning and performance enhancement. Built for enthusiasts and professional mechanics who demand consistent ride control and load handling, this rear spring delivers the predictable performance characteristics required for everything from daily-driver refinement to track-focused modifications. EIBACH springs have long been the industry standard for suspension upgrades, trusted by tuners and OEM manufacturers alike for their reliability and engineered consistency.

This rear spring features a 20-inch length, 5-inch coil diameter, and a 100-pound spring rate, making it ideal for applications requiring moderate to firm suspension stiffness. The 100# rate provides excellent load support while maintaining compliance on rough surfaces—a critical balance for vehicles running modest lowering packages or aftermarket wheel-and-tire combinations. EIBACH's manufacturing precision ensures consistent spring rates across the entire load range, eliminating the performance variations common in budget alternatives. The spring's geometry and material composition are engineered to resist fatigue and maintain rate stability through thousands of cycles, whether on street or strip.

This Spring Rear 20in x 5in x 100# is best suited for custom suspension builds, ride-height adjustments, and load-bearing upgrades on domestic and import platforms. Mechanics often pair these springs with quality shocks and sway bars to achieve integrated handling improvements. Before installation, verify fitment with your vehicle's year, make, and model—spring rates and dimensions vary by application. Proper installation by a qualified technician ensures correct suspension geometry, ride quality, and safety. This spring is an excellent choice for anyone seeking controlled, predictable rear-end performance without the harshness of excessively stiff rates.
