KYB 345615 Suspension Shock Absorber - Front

KYB Excel-G Shock Absorber for OE-Style Control

KYB Excel-G part number 345615 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 made on KYB OE assembly lines with OE-quality components and is calibrated to return the vehicle to its designed performance.

The Excel-G line is KYB’s OEA-style replacement range, focused on preserving factory handling characteristics rather than changing ride behavior. For heavy-duty truck and commercial vehicle applications, 345615 is a direct-fit suspension shock absorber engineered for consistent damping and controlled body motion.

• Vehicle-specific, hand-assembled damping valves manage tire contact, steering response, and body movement
• Made in USA
• Supports proper operation of electronic safety systems by helping suspension, brakes, and tires work as engineered
• Strong, thick strut body and bracket design helps minimize flex and maintain alignment
• Dust cover included

Detailed Description

KYB 345615 is part of the Excel-G brand line, which is built for drivers and technicians who want factory-style suspension response after shock replacement. This shock absorber uses a twin-tube, nitrogen gas-charged design and OE-quality construction to help maintain predictable ride control under load, during braking, and through directional changes. The compressed length is 18.05 inches, extended length is 30.75 inches, and stroke length is 12.70 inches. Mounting points are E1L/E(19) on the lower end and E1-L/E(19) on the upper end.

For buyers searching for a KYB 345615 shock absorber, Excel-G replacement shock, or a suspension shock absorber for heavy-duty truck and commercial vehicle service, this part is built to match original damping behavior. It is also a practical choice when replacing worn shocks on applications such as Ford F-250 and Ford F-350 trucks where stable ride control and steering response matter.

This part cross-references Monroe Shocks & Struts 66863 for the same application.

What It Helps Address

• Excessive bouncing after bumps
• Loose or unstable steering feel
• Longer stopping distances caused by worn damping
• Body roll during lane changes and cornering
• Uneven tire contact from reduced suspension control

Installation Notes and Tips

Verify mount style, compressed length, extended length, and stroke length before installation. This shock uses E1L/E(19) lower and upper mount types, so confirm the vehicle’s original hardware and bracket configuration match the part. Inspect related suspension components, including bushings, mounts, and tires, before installing a new shock absorber.

For fitment-based searches, this KYB Excel-G shock absorber is listed for 1999-2004 Ford F-250 and 1999-2004 Ford F-350 applications. Confirm position and chassis details against the vehicle catalog before ordering.

Quality Assurance

KYB supplies shocks and struts to new vehicle manufacturers and builds Excel-G on the same OE assembly lines using OE-quality components. The design is calibrated to restore original performance characteristics, and the brand’s OE supplier background supports consistent manufacturing standards for replacement suspension service.
