89~94 SILVIA (S13) Includes front and rear TWR air springs and dampers.
THREADED BODY FOR HEIGHT ADJUSTMENT
All TWR Air-Over struts include threaded shock bodies and spanner lock nuts allow you to select the spring stiffness that best fits your driving style and preference. Air Springs have variable stiffness depending on the height that you choose to operate them at; taller = stiffer and shorter = softer (typically). Proper spring stiffness at driving height is critical for optimal vehicle ride quality and performance.
36 LEVEL ADJUSTABLE DAMPING
Adjustment knobs at the top of the shock shaft allow you to select the damper stiffness that best fits your driving style and preference. Proper damper stiffness is critical for optimal vehicle ride quality and performance. All TWR dampers feature 36 levels of adjustable damping for all 4-corners of your vehicle.
ISOLATED TOP MOUNTS
Vehicle-specific top mounts with robust rubber isolation and bearings (when applicable) provide optimal vibration isolation and quite suspension operation.
ALL HARDWARE INCLUDED
Each vehicle's suspension design is slightly different and TWR has determined exactly what parts are required for a complete air suspension installation on each and every application. In addition to just nuts and bolts, some applications may include additional components such as sway bar linkage, brackets, bushings, and spacers.
