KYB KG54324 Shock Absorber - Rear

KYB Gas-a-just Rear Shock for Jeep TJ and Wrangler

The KYB Gas-a-just KG54324 is a rear monotube shock absorber built for 1997-2006 Jeep TJ and 1997-2006 Jeep Wrangler applications. It is engineered to deliver firmer control than a conventional twin-tube design while maintaining a comfortable ride during normal driving.

Gas-a-just shocks use separate hydraulic and high-pressure gas chambers to reduce fade from aeration and provide quicker response when suspension demands increase. For Jeep TJ and Wrangler owners looking for a rear shock that handles daily use, towing, larger tires, and heavier wheel setups, the KG54324 is a direct-fit suspension service part.

Product Details

The KYB Gas-a-just line is built around a monotube layout with an air-free hydraulic working area and a separate gas chamber. That design supports fast rebound control, stable steering response, and fade-resistant operation when the suspension is working harder than stock. On Jeep TJ and Wrangler rear suspension setups, KG54324 is a practical choice for vehicles that see mixed street use, off-road driving, towing, or added unsprung weight from larger tires and wheels.

Measured specifications include a compressed length of 12.36 inches, extended length of 19.02 inches, and stroke length of 6.65 inches. Lower mount type is E2(12X36) and upper mount type is E3(68.5X95X0). The part number KG54324 also cross-references Monroe Shocks & Struts 911541 for the same application.

Common Problems This Shock Can Address

• Excessive rear bounce or oscillation over bumps
• Reduced control from worn OE-style shocks
• Shock fade during repeated suspension movement
• Loose rear-end feel on Jeep TJ and Wrangler models
• Reduced steering response from tired suspension damping

Installation Notes and Tips

Fits 1997-2006 Jeep TJ, rear. Fits 1997-2006 Jeep Wrangler, rear. Verify mount style, compressed length, and extended length before installation to confirm proper suspension travel and ride height clearance.
