TEIN VSTA9-A1MS2 EnduraPro Rear Shock Absorber

The TEIN VSTA9-A1MS2 is an EnduraPro rear shock absorber designed for the 2005-2010 Toyota Sienna 8-seat models (MCL/GSL25L). This high-performance OE-shape shock absorber is designed to work with the vehicle's original spring and upper mount, with a lower spring seat shaped identical to the OE shock absorber.

Key Features:

• Shell case with tensile strength approximately 150% stronger than OE variants, featuring a larger diameter for increased oil capacity
• Twin-tube design attains longer strokes with smaller repulsive force, resulting in high ride comfort
• Hydraulic Bump Stopper (HBS) mechanism provides comfortable ride even with heavy loads by converting stroke impact to thermal energy
• TEIN's patented 2-Layer, 1-Bake powder coating method with corrosion-proofing paint for superior durability and rust protection, ideal for regions with heavy snowfall or coastal areas
• 22mm outer diameter piston rod compared to typical OE 20mm or less for improved performance
• Quick and hassle-free integration with OE spring and upper mount

The TEIN EnduraPro series represents a premium replacement shock absorber solution that exceeds OE specifications while maintaining original fitment. Perfect for replacing worn or leaking dampers, or for upgrading ride quality and handling performance without changing ride height. Can also be paired with TEIN lowering springs for enhanced performance.
