KYB KG4536 Shock Absorber - Rear

KYB Gas-a-just Rear Shock for Classic GM

The KYB Gas-a-just KG4536 is a rear monotube shock absorber built for classic GM compact cars that need firmer control and quicker response. It is engineered for vehicles such as the Buick Skylark, Chevrolet Cavalier, Pontiac Grand Am, and related rear applications from 1982-1994.

Gas-a-just shocks use separate gas and oil chambers to reduce fade and maintain consistent damping during normal driving, towing, and use with larger wheels and tires. The KG4536 is a direct-fit suspension shock absorber for rear applications across a wide range of GM platforms.

Key Features

• Up to 25% more damping performance than original equipment shocks
• Monotube design separates gas and oil for fade-resistant operation and fast response
• Higher gas pressure improves steering response and body control
• Triple chrome plated piston rod helps reduce seal wear and fluid leakage
• Valving and components are tuned for classic GM cars
• Dust cover included
• Cross-references Monroe Shocks & Struts 5896 and Gabriel 69749 for the same application

Product Details

KYB Gas-a-just shocks are built around a high-pressure monotube layout with an air-free hydraulic working area and a separate nitrogen gas chamber. That design gives the KG4536 quick reaction over bumps, stable damping under load, and consistent performance when the suspension is working harder than stock. For rear suspension service on a Buick Skylark, Chevrolet Cavalier, or Pontiac Grand Am, this part number offers a performance-oriented OE-style replacement with dimensions of 13.58 inches compressed length, 21.73 inches extended length, and 8.15 inches stroke length.

Common Problems This Shock Can Address

• Excessive rear bounce after bumps or dips
• Reduced control during braking, cornering, or lane changes
• Shock fade from heat and aeration during extended driving
• Loose rear-end feel on classic GM compact cars
• Uneven ride quality with heavier wheels and tires
