KYB 341628 Suspension Shock Absorber - Rear

KYB Excel-G Shock Absorber 341628

The KYB Excel-G 341628 is a nitrogen gas-charged, twin-tube suspension shock absorber built to restore original ride control, stability, and handling. It is made on KYB OE assembly lines with OE-quality components and is calibrated to return the vehicle to its designed performance rather than change it.

For Freightliner heavy duty truck and commercial vehicle applications, this KYB Excel-G shock absorber supports consistent steering response, body control, and braking stability. It is a direct-fit OE replacement choice for Freightliner suspension service and is also referenced by Monroe Shocks & Struts 65490 and Gabriel 85724 for the same application.

Key Features

• KYB recommended OEM replacement shock for heavy duty trucks and commercial vehicles
• Vehicle-specific, hand-assembled damping valves manage tire contact, steering response, and body movement
• Triple-lip fluid seal helps reduce oil and gas leakage
• Strong strut body and bracket design helps minimize flex and maintain alignment
• Made in USA
• Dust cover included
• R-stop included

Product Details

The Excel-G line is KYB’s Original Equipment for the Aftermarket solution, engineered to match the original suspension behavior of the vehicle. Part number 341628 uses a twin-tube, nitrogen gas-charged design with a 15-inch compressed length, 22.88-inch extended length, and 7.88-inch stroke. Mounting dimensions are E2(19X80.7) at the lower end and E2(19X96.5) at the upper end.

For Freightliner suspension repair, this shock absorber helps maintain the control needed for lane changes, load stability, and predictable handling. If you are replacing worn Freightliner shocks and want an OE-style ride restoration, KYB 341628 is built for that service.

What It Helps Address

• Excessive bouncing after bumps or rough-road travel
• Reduced steering response during lane changes
• Body sway and instability under load
• Longer stopping feel caused by worn suspension damping
• Uneven tire contact from weak shock control

Installation Notes and Tips

Verify mounting style, compressed length, extended length, and stroke before installation. Confirm the Freightliner application against the vehicle’s suspension configuration and compare the original shock dimensions to KYB 341628. Inspect related suspension components, bushings, and mounting points during replacement so the new shock can operate as intended.

Quality Assurance

KYB supplies shocks and struts to new vehicle manufacturers and builds the Excel-G line on the same OE assembly lines using OE-quality components. That OE-focused manufacturing approach supports consistent fit and performance for Freightliner commercial vehicle suspension service.
