KYB Stock Height Rear Shock (1984-95 4Runner)

KYB Stock Height Rear Shock Absorber

For 1984–1995 Toyota 4Runner

Overview

The KYB Gas-a-Just is a high-pressure, gas-charged monotube rear shock absorber for factory-height Toyota 4Runner suspensions. Two distinct rear-mount configurations cover the first- and second-generation 4Runner, with single-shock and rear-pair purchase choices.

Its floating piston separates the nitrogen gas from hydraulic fluid to resist aeration and promote consistent damping. Each rear shock is designed for installation on either the left or right side of its specified application.

Key Features

• High-pressure monotube construction for responsive suspension damping
• Gas and hydraulic chambers separated by a floating piston to help control aeration
• Application-specific rear mounting designs for first- and second-generation 4Runner models
• Stock-height replacement for factory-style rear suspension geometry
• Single or pair availability to suit one-side replacement or both rear wheels
