Product Details

The KYB Excel-G line is engineered to return a vehicle to its original designed performance rather than change the ride character. For Ford E-350 Super Duty rear shock replacement and other E-Series rear suspension applications, KYB 344371 uses OE-quality components assembled on the same KYB production lines that supply new vehicle manufacturers. This makes it a practical choice for restoring control on work vans and passenger vans where predictable handling, braking stability, and lane-change response matter.

This part cross-references Monroe Shocks & Struts 34761 for the same application.

What It Helps Address

• Excessive bouncing after bumps or dips
• Rear-end sway or instability during lane changes
• Reduced braking confidence caused by worn rear shocks
• Poor tire contact and uneven body motion over rough roads
• Loss of factory ride control on high-mileage Ford E-Series vans
