KYB KG5415 Shock Absorber - Rear

KYB Gas-a-Just Rear Shock Absorber

The KYB Gas-a-just KG5415 is a rear suspension shock absorber built for GM trucks and SUVs that need firmer control, quicker response, and stable damping under load. It uses a monotube design with separate gas and oil chambers to maintain consistent performance during normal driving and demanding conditions.

Compatible with rear applications on Chevrolet Blazer, GMC Jimmy, Chevrolet C/K and GMC C/K trucks, and related Suburban and utility models, this shock is a direct-fit option for classic GM suspension service. The KG5415 is engineered for vehicles that tow, carry weight, or run larger tires and wheels.

Gas-a-Just Line Details

KYB Gas-a-Just shocks are designed for drivers who want more control than a conventional twin-tube design. The high-pressure monotube construction helps reduce fade from aeration, while the internal gas pressure supports faster steering response and more consistent damping when road conditions change.

• Up to 25% more damping performance than original equipment shocks
• Monotube design separates gas and oil for fade-resistant operation
• High-pressure nitrogen chamber delivers instant response
• Triple chrome plated piston rod helps reduce seal wear
• Built for GM truck and SUV rear suspension applications
• Dust cover included

Detailed Product Overview

Part number KG5415 is a rear suspension shock absorber from KYB’s Gas-a-just line. It measures 14.21 inches compressed, 22.95 inches extended, and 8.74 inches of stroke, with lower mount type E2 (14.6 x 41) and upper mount type E1. The monotube layout gives the shock an air-free hydraulic working area for control and a separate high-pressure nitrogen section for ride comfort and immediate damping response. This makes the KYB Gas-a-just KG5415 a practical choice for Chevrolet Blazer and GMC Jimmy rear suspension service, as well as other listed GM truck and Suburban applications.

What This Shock Absorber Helps Address

• Excessive rear-end bounce over bumps and uneven pavement
• Reduced control when towing or carrying heavier loads
• Delayed steering response from worn rear shocks
• Shock fade caused by aeration in conventional twin-tube designs
• Ride instability on GM trucks and SUVs with larger tires and wheels
