The KYB Excel‑G rear struts 334394/334395 are gas-charged, twin-tube dampers designed as direct-fit replacements for AWD Lexus RX330/350 and Toyota Highlander models (2004–2007). Precisely valved on OEM production lines with hand-assembled damping valves, triple-chrome piston rods, and sintered-iron guides, they offer factory-grade compression and rebound control to smooth road irregularities, reduce body roll, and maintain consistent tire contact—ensuring stable, comfortable handling and braking performance. With seamless steel tubing, multi-lip seals, and nitrogen pressurization to prevent fluid aeration, these shocks restore ride quality and drivetrain confidence—especially important in larger SUVs on rough roads .

Built for longevity, the 334394/334395 set often exceeds 150,000 miles without performance loss or leakage, thanks to corrosion-resistant construction and factory hardware included for easy bolt-on installation. Their precise damping characteristics help restore original handling dynamics, making them a cost-effective upgrade that brings back your vehicle’s smooth, controlled ride with minimal hassle—ideal for owners aiming to maintain showroom-level suspension performance in their Lexus or Highlander.
