The KYB Gas‑a‑Just rear shock for 2019–2022 Nissan Altima FWD is a monotube replacement that restores original ride characteristics. It uses two separate working chambers—an air‑free hydraulic piston and a high‑pressure nitrogen gas section with a floating piston—to deliver responsiveness, control and a comfortable ride. KYB notes this design helps maintain the intended performance of vehicle electronic safety systems.
