Spring Rear 16in x 5in x 175# Platinum

The Spring Rear 16in x 5in x 175# Platinum coil spring is engineered for serious suspension tuning and vehicle modification. Built by Eibach, a leader in performance spring design for over 70 years, this rear spring delivers the stiffness and consistency that mechanics and automotive enthusiasts demand when upgrading handling characteristics. Whether you're lowering your vehicle, fine-tuning ride height for improved aerodynamics, or building a track-focused setup, this 175-pound-rate spring provides predictable load support and reduced body roll under cornering stress.

With a 16-inch length and 5-inch free length specification, this Platinum-grade coil spring is manufactured to tight tolerances that ensure consistent spring rate across the lifespan of your suspension system. The 175-pound spring rate strikes a balance between comfort on street applications and responsive handling on spirited driving—stiff enough to minimize squat during acceleration and dive under braking, yet compliant enough to maintain tire contact over uneven pavement. Eibach's proven manufacturing process guarantees uniformity in coil pitch and wire diameter, eliminating the performance variability that plagues cheaper aftermarket alternatives.

This rear spring is ideal for daily-driver modifications, autocross setups, and custom suspension builds where you need reliable spring rates paired with OEM-quality durability. Installation requires removing the factory spring and mounting hardware—a task well within the scope of any home mechanic or professional shop. Always pair this spring with matching front springs and verify your vehicle's suspension geometry and anti-roll bars to ensure balanced handling. At 6.65 lbs per unit, this spring integrates seamlessly into complete suspension kits and works with both stock and upgraded dampers.
