KYB 345071 Shock Absorber - Rear

KYB Excel-G Rear Shock for Ford F-350 Super Duty

The KYB Excel-G 345071 is a rear suspension shock absorber built to restore original ride control on the 2005-2010 Ford F-350 Super Duty. It is an OE-style replacement for drivers who want stable handling, predictable braking response, and consistent lane-change control without changing the truck’s factory tuning.

Made on KYB OE assembly lines, the Excel-G line is calibrated to return the vehicle to its designed performance. For heavy-duty Ford truck applications like the F-350 Super Duty, that means controlled damping, reduced body motion, and suspension behavior that stays aligned with the original engineering intent.

Product Details

Part number 345071 is part of KYB’s Excel-G product line, which focuses on original-equipment-style replacement rather than altered ride characteristics. This line is built using OE-quality components and calibrated damping to match the truck’s factory suspension behavior. Compatible with 2005-2010 Ford F-350 Super Duty rear applications, 345071 is a direct-fit suspension shock absorber for restoring control in demanding truck use.

This part cross-references Monroe Shocks & Struts 911265 for the same application.

What It Helps Address

• Excessive rear-end bounce after bumps or dips
• Loose or unsettled handling during lane changes
• Reduced braking stability caused by worn rear shocks
• Uneven tire contact from weak damping control
• Body movement that feels less controlled under load

Installation Notes and Tips

Fits 2005-2010 Ford F-350 Super Duty, rear. Replace the suspension strut and coil spring assembly according to the manufacturer’s instructions. Verify mount style and dimensions before installation: compressed length 13.62 in., extended length 22.28 in., stroke length 8.66 in., lower mount type E2(12X38), upper mount type E1.

For best results, inspect related suspension components such as springs, mounts, and bushings during service. Proper installation helps the shock absorber perform as calibrated and supports consistent ride control on the Ford F-350 Super Duty.
