This design supports a comfortable ride during normal use while helping the suspension respond effectively under increased load or more aggressive driving.

Properly functioning suspension components also contribute to the operation of vehicle safety systems. The KYB Gas-a-Just helps the suspension, brakes, and tires perform closer to the vehicle manufacturer's intended specifications, supporting the effectiveness of electronic safety systems. This rear shock is designed for select 2022–2026 Nissan Frontier Pro-X and Pro-4X applications. Verify the vehicle application before installation.
