4000 Series Coil-Over Kit 5in

The INTEGRA SHOCKS 4000 Series Coil-Over Kit 5in is designed for automotive enthusiasts and professional mechanics who require precise suspension tuning for independent rear suspension (IRS) platforms. This coil-over assembly is ideal for street enthusiasts, track builders, and drift competitors who prioritize ride quality and handling dynamics.

Featuring a 5-inch stroke design, the 4000 Series allows for independent spring preload and damping adjustments, enabling fine-tuning of both compression and rebound characteristics. The coil-over architecture effectively isolates spring rate from damping force, providing the ability to enhance ride comfort without compromising body control or the vehicle's anti-squat and anti-dive geometry.

This kit is compatible with IRS-equipped platforms, including modern sport coupes, muscle cars, and European performance sedans, where the rear-end geometry can greatly benefit from adjustable height and stiffness. Proper installation and alignment are essential to maintain optimal bump steer and camber curves for improved performance.
