The ISC Suspension N1 V2 Coilover System for the 1989-1994 Nissan 240SX (S13) is the optimum suspension tool for improved handling for your street or weekend track car. The ISC N1 V2 comes standard with pillowball upper mounts, and camber plates when applicable. This suspension is perfect for someone looking for performance, adjustability (height and damping) and other quality features. Over a decade of experience and feedback has allowed the ISC N1 V2 to evolve into what it is today; a premium suspension for car enthusiasts.

The ISC N1 V2 coilover system features a Limited Lifetime Warranty to the original purchaser. Our Coilovers are a single cylinder monotube design, with 32 way adjustable damping to dial in ride quality and performance to your preference. Preload adjustment is separate from ride height adjustment on all of our coilovers; this allows the vehicle to be lowered, without sacrificing ride quality. Our springs are made from SAE9254 steel, dyno tested over 500,000 times with under 5% deformation. All ISC coilovers are ISO and ARTC Certified.

Select ISC N1 V2 coilovers are also compatible with our ISC Triple S upgraded coilover springs for additional customization and performance.
