KYB Suspension Shock Absorber P/N:554367
Get the KYB shock absorber that puts factory ride control back under your Chevrolet Avalanche 1500 — the KYB Excel-G Gas Shock, MPN 344436, a direct-fit REAR shock for the 2002-2006 Chevrolet Avalanche 1500 (see the Buyer's Guide tab for engine-level fitment). Excel-G is nitrogen gas-charged with a twin-tube design, built on the same KYB OE assembly lines with the same OE-quality components and calibrated to restore original designed performance — earning it KYB's OEA (Original Equipment for the Aftermarket) classification.
The KYB Excel-G shock absorber is a KYB-recommended OEM replacement and a preferred choice among professional technicians. Shocks wear as a set — replacing both rear units together helps keep damping balanced side to side.
