KYB 341623 Suspension Shock Absorber - Rear

KYB Excel-G Shock Absorber 341623

KYB Excel-G 341623 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, with the same type of calibration used on KYB original equipment production lines.

Compatible With heavy-duty truck and commercial vehicle suspension applications, this shock absorber is designed to return the vehicle to its intended damping performance without changing the factory ride character. The KYB Excel-G line is commonly selected when the goal is to correct worn suspension behavior while keeping OE-like control.

Key Features

• Nitrogen gas-charged, twin-tube design
• OE-quality components assembled on KYB production lines
• Vehicle-specific damping valves for tire contact, steering response, and body motion control
• Triple-lip fluid seal to reduce oil and gas leakage
• Strong strut body and bracket construction to help minimize flex and maintain alignment
• Dust cover included
• R-stop included
• Made in USA

Product Details

The KYB Excel-G brand line is focused on restoring factory ride control rather than altering suspension behavior. Part number 341623 uses OE-style engineering and hand-assembled damping calibration to help the suspension respond the way the vehicle manufacturer intended. This part cross-references Monroe Shocks & Struts (e.g., 65409) and Gabriel (e.g., 85003) for the same application. For buyers searching for KYB 341623, Excel-G shock absorber replacement, or an OE-style suspension shock for commercial use, this part is built around those requirements.

What It Helps Correct

• Excessive bouncing after bumps
• Loose or unstable handling during lane changes
• Longer stopping feel caused by worn damping
• Poor tire contact and uneven body movement
• Reduced steering response from tired suspension components

Installation Notes and Tips

Verify compressed length, extended length, stroke length, and upper/lower mount type before installation. This unit measures 15.74 inches compressed, 25.24 inches extended, and 9.5 inches of stroke, with E2(16X50.8) upper and lower mounts. Inspect related suspension parts, bushings, and mounting points before replacing the shock absorber. After installation, confirm ride height, fastener torque, and alignment condition according to the vehicle service procedure.

Quality Assurance

KYB supplies shocks and struts to new vehicle manufacturers, and Excel-G is produced on KYB OE assembly lines using OE-quality components. The design is calibrated to restore original performance characteristics and support the operation of vehicle safety systems that depend on suspension, brakes, and tires working as engineered.
