Silver's NEOMAX Coilovers - for 1989-1994 Nissan Silvia / 180SX & 240SX (S13)

Engineered for the Nissan S13 Silvia / 180SX / 240SX chassis, these performance coilovers deliver track-ready handling without sacrificing daily-drive comfort:

Fully adjustable T6-6061 front camber plates for all MacPherson-strut S13 Silvia and 240sx applications let you dial-in aggressive camber settings for drift or grip driving.

Koyo Japan Radial-Bearing Upper Spring Perches—standard on every MacPherson S13 kit—eliminate spring bind and noise, giving the driver smoother steering feel and sharper feedback.

24-way Damper Adjustability: each positive-click pairs with premium shock oil so every change is felt in your fingertips and the driver’s seat.

High-Strength JIS G3445-STKM13C Carbon-Steel Shock Tubes (52mm seamless) withstand hard cornering and rough pavement common to modified S13/RPS13 180SX / 240SX builds.

44mm piston with digressive valving maximizes low-speed damping for superior chassis control while maintaining a compliant ride on the street.

Monotube design increases oil volume and piston displacement over twin-tube setups, boosting heat dissipation for consistent performance during extended S14 Silvia track sessions.

High-viscosity IP F.A. 5W damper oil preserves damping consistency lap after lap.

True-height adjustment at the lower bracket—no need to alter spring preload—maintains full suspension travel regardless of ride-height, perfect for stanced S13 Coupe or Fastbacks.

Cold-wound SAE9254 springs retain a stable elastic modulus even after repeated drifting loads.

Powder-coated steel lower brackets mirror factory brake-line and ABS tabs for a hassle-free install.

Anodized T6-6061 aluminum lower mounts on multi-link rears cut unsprung weight for faster S-chassis response.

Backed by a 5-year limited manufacturer’s warranty for peace of mind on your S13/RPS13 build.

Default spring rates: Front 8 kg/mm | Rear 5 kg/mm — Custom Springs Rates are available along with the upgrade to Swift Springs.
