KYB 341633 Suspension Shock Absorber - Rear

KYB Excel-G Shock Absorber 341633

KYB Excel-G 341633 is a nitrogen gas-charged, twin-tube suspension shock absorber built to restore original ride control, stability, stopping response, lane-change handling, and steering feel. It is an OE-style replacement for heavy-duty trucks and commercial vehicles, including applications such as Ford F-250 and Ford F-350, where consistent damping and body control matter.

The Excel-G line is assembled on KYB OE production lines using OE-quality components and calibrated to return the vehicle to its designed performance. This part number, 341633, is a direct-fit suspension shock absorber for drivers and technicians looking for factory-style ride characteristics rather than a changed ride feel.

Excel-G Product Line Details

KYB Excel-G is the brand’s OEA-style replacement line, built to match original suspension behavior rather than alter it. For Ford F-250 and Ford F-350 owners, that means predictable damping, stable highway tracking, and consistent response under load. Part number 341633 follows KYB’s OE-focused approach for service replacement on trucks that rely on suspension performance for control and safety-system operation.

What This Shock Absorber Helps Address

• Excessive bouncing after bumps or dips
• Loose or unstable steering feel
• Reduced body control during lane changes and braking
• Uneven tire contact caused by worn damping
• Suspension noise or fluid leakage from a worn shock

Installation Notes and Fitment

Compatible with select Ford F-250 and Ford F-350 applications. Fits 2005-2016 Ford F-250, rear; fits 2005-2016 Ford F-350, rear. Verify mount style and dimensions before installation: compressed length 16.27 in, extended length 26.72 in, stroke length 10.45 in, lower mount type E1L/E(26), upper mount type E1-L/E(26). This part cross-references Monroe Shocks & Struts (e.g., 66891) for the same application.

Use standard suspension service practices during replacement, and inspect related wear items such as bushings, mounts, and tires while the shock is removed. Proper installation helps the vehicle maintain the ride control and alignment behavior the chassis was designed to deliver.
