KYB 343395 Shock Absorber - Rear

KYB Excel-G Rear Shock Absorber

KYB Excel-G 343395 is a rear suspension shock absorber built to restore original ride control, stability, and handling. It is a nitrogen gas-charged, twin-tube design made on KYB OE assembly lines with OE-quality components for direct replacement performance on supported GM SUVs and related applications.

The Excel-G line is KYB’s OEA-style replacement series, focused on returning the vehicle to its designed damping characteristics rather than changing ride feel. For rear suspension service on Chevrolet Trailblazer, GMC Envoy, and related platforms, 343395 is engineered for consistent control and predictable response.

• KYB recommended OEM replacement shock for SUVs and crossovers
• Restores designed control and handling for GM SUV rear suspension applications
• Triple-lip fluid seal helps reduce oil and gas leakage
• Vehicle-specific, hand-assembled damping valves manage tire contact, steering response, and body movement
• Supports proper operation of electronic safety systems by maintaining suspension behavior as engineered
• Strong, thick strut body and bracket construction helps minimize flex and maintain alignment
• Dust cover included

What This Shock Absorber Helps Address

• Excessive rear-end bounce after bumps
• Loose or unstable handling in lane changes and cornering
• Reduced tire contact from worn damping control
• Uneven ride quality caused by aging rear shocks
• Suspension noise or poor body control from worn OE-style dampers

Installation Notes

Replace the suspension strut and coil spring assembly according to the manufacturer’s instructions where specified. Verify mount style, compressed length, extended length, and stroke length before installation. For GM SUV rear applications, confirm the vehicle’s exact model and year against the fitment list for the correct rear shock absorber.

Quality Assurance

KYB manufactures Excel-G on the same OE assembly lines used for original equipment supply, using OE-quality components and application-specific damping calibration. The design is intended to restore factory ride control and handling characteristics for supported Chevrolet Trailblazer, GMC Envoy, and related rear suspension applications.
