KYB Excel-G Shock Absorber for OE Ride Control
KYB Excel-G 345609 is a nitrogen gas-charged, twin-tube suspension shock absorber built to restore original ride control, stability, and steering response. 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.
The Excel-G line is focused on returning the vehicle to its designed handling balance rather than changing the ride. For drivers and technicians servicing a heavy duty truck or commercial vehicle, KYB 345609 provides a direct replacement approach that supports consistent tire contact and body control.

Excel-G Product Line Details
KYB Excel-G is KYB’s Original Equipment for the Aftermarket line. It is built on the same KYB OE assembly lines and uses OE-quality components to match original damping characteristics. That makes KYB 345609 a practical choice when the goal is to restore factory ride behavior on a truck or commercial chassis, including applications where suspension performance affects braking and electronic safety system operation.
This part cross-references Monroe Shocks & Struts 66653 for the same application.
What It Helps Address
- Excessive bounce after bumps or dips
- Loose or unstable steering feel
- Poor lane-change response
- Uneven tire contact caused by weak damping
- Body movement that affects braking and handling consistency
Installation Notes
Verify compressed length, extended length, stroke, and mount types before installation. KYB 345609 uses a lower E1L/E(19) mount and an upper S1(3/8) mount, so matching the existing suspension hardware is important for correct installation. After replacement, inspect alignment and confirm that the suspension moves freely without binding.
