The KYB Excel‑G front struts 334450 (right) and 334451 (left) are gas-charged, twin-tube dampers engineered as direct-fit replacements for the 2003–2008 Toyota Corolla. Built on the same OEM assembly lines and calibrated with hand-assembled valving tailored to the Corolla’s weight and suspension characteristics, these struts provide precise control over compression and rebound. Reinforced with triple-chrome piston rods, seamless steel cylinders, sintered-iron guides, nitrogen pressurization, and multi-lip seals, they effectively renew the vehicle's ride comfort, stabilize handling, and maintain steady tire-to-road contact—restoring the smooth, factory-level driving experience.

Durability is a standout feature for these struts: many owners report consistent, leak-free performance well beyond 150,000 miles, owing to the robust materials and resistant construction . Installation is uncomplicated—a simple bolt-on with included factory mounting hardware—allowing Corolla drivers to quickly rediscover sharp steering response, reduced front-end bounce, and renewed ride refinement. Overall, this pair represents a cost-effective upgrade to restore or enhance the vehicle's original suspension feel.
