Detailed Description

KYB 344403 is part of the Excel-G product line, a replacement shock absorber engineered to return the suspension to the vehicle’s original operating characteristics. For rear suspension service on Jeep TJ and Jeep Wrangler models, this shock is designed to support controlled body motion, stable lane changes, and predictable stopping behavior by maintaining proper tire contact and damping response. The part number 344403 is a practical choice when the goal is restoring factory-style performance rather than altering ride feel.

This part cross-references Monroe Shocks & Struts 37135 for the same application.

What It Helps Address

• Excessive bouncing or oscillation after bumps
• Loose rear-end feel during cornering or lane changes
• Reduced braking stability caused by worn shocks
• Uneven tire contact from weak damping control
• Noisy or inconsistent rear suspension response
