Nissan B15 Shocks

Product Description: Nissan Sunny / Sentra / Wingroad (B15 / N16 Chassis, 1998–2006) Shock Absorbers / Suspension Struts

Overview

The Shock Absorber & Suspension Strut Set for the Nissan Sunny / Sentra / Wingroad (B15, FB15, N16 Chassis Series, 1998–2006) is an OEM-spec replacement engineered to restore original ride comfort, steering responsiveness, and chassis stability. Precision-built to match Nissan’s compact vehicle architecture, these gas-charged shocks eliminate vehicle bounce, reduce nose-diving under braking, and maintain firm tire-to-road contact for smooth, predictable daily driving.

Key Features & Performance Benefits

1. Restored Original Ride Comfort: Dampens harsh road vibrations, potholes, and high-frequency road noise to keep the cabin quiet and smooth.

2. Eliminates Nose Dive & Body Roll: Reduces front-end dipping during heavy braking and controls sway during sharp cornering or sudden lane changes.

3. Enhanced Tire Contact & Safety: Keeps tires firmly planted on the road surface, optimizing stopping distances and preventing irregular tread wear.

4. All-Weather Protection: Fitted with high-spec multi-lip rubber oil seals and corrosion-resistant body coatings to prevent hydraulic leaks and rust formation.
