KYB KG5436 Suspension Shock Absorber - Rear

KYB Gas-a-just Shock Absorber KG5436

The KYB Gas-a-just KG5436 is a monotube suspension shock absorber built for trucks and other vehicles that carry heavier loads, tow, or run larger wheels and tires. Its high-pressure gas design separates oil and gas for quick response, consistent damping, and reduced fade during demanding driving.

Gas-a-just Performance Line

KYB’s Gas-a-just line is engineered for drivers who want firmer control than a traditional twin-tube shock can provide. The monotube construction uses separate working chambers for hydraulic response and nitrogen gas pressure, helping the shock react quickly while maintaining a more controlled ride under load.

Key Features

• Adds up to 25% more damping performance over original equipment shocks
• Monotube design separates gas and oil for fade-free operation and instant response
• Higher gas pressure improves steering response
• Triple chrome plated piston rod helps reduce seal wear and fluid leakage
• Designed for heavy-duty trucks and vehicles that work, tow, or use larger, heavier tires and wheels
• Dust cover included
• B-stop and R-stop included in the design

Detailed Description

KYB KG5436 is a suspension shock absorber that uses a high-pressure monotube layout to deliver more consistent control than many OE twin-tube designs. The air-free hydraulic piston area handles responsiveness, while the nitrogen gas chamber supports ride comfort during normal driving and adds damping on demand. This design helps maintain stability when the suspension is working harder, such as during towing, hauling, or rough-road use. For shoppers comparing KYB KG5436 against Monroe Shocks & Struts 555046 or Gabriel 82061, this part serves the same application family. It is a strong match for drivers searching for a heavy-duty truck shock absorber, KYB Gas-a-just shock for work truck suspension, or a replacement shock absorber for vehicles with oversized tires and wheels. Compatible With select truck and SUV suspension applications, including vehicle-specific setups where the original shock dimensions match the listed compressed length of 12.91, extended length of 18.66, and stroke length of 5.75.

What It Helps Address

• Excessive body motion over bumps and uneven pavement
• Reduced steering response from worn or weak shocks
• Shock fade during repeated suspension movement
• Fluid leakage caused by seal wear
• Loss of control feel on trucks used for towing or hauling

Installation Notes and Tips

Verify upper mount type E1 and lower mount type E2 (14.6 x 41) before installation. Confirm compressed length, extended length, and stroke length against the original shock absorber to ensure proper suspension travel and mounting alignment. Inspect surrounding suspension components, bushings, and mounts for wear before replacing the shock. For best results, replace shocks in axle pairs when the vehicle calls for matched damping performance.

Quality Assurance

KYB is a major OE supplier, and the Gas-a-just line is built with application-specific valving and heavy-duty construction to support consistent suspension control. The KG5436 is engineered to help keep suspension, braking, and electronic safety systems operating as the vehicle manufacturer intended.
