EnduraPro SP Kit

• 2008-2014 Subaru | WRX STI

The TEIN EnduraPro SP Kit is a high-performance OE-shape shock absorber kit for the 2008-2014 Subaru WRX STI. Designed to use the vehicle's original (OE) spring and upper mount, it replaces worn or leaking OE dampers and can improve ride quality and handling without changing ride height. Part number: VSS84-A1DS2.

• OE-shape shock absorber designed to be used with the vehicle's original (OE) spring and upper mount, with a lower spring seat shaped identical to the OE shock absorber.
• Hydraulic Bump Stopper (H.B.S.) internally converts the impact of a full stroke to thermal energy (heat) and absorbs it, reducing the impact that disturbs the vehicle's behavior and contributing to damper durability.
• Twin-tube system attains longer strokes with a smaller repulsive force, resulting in high ride comfort, a smooth ride at low speed and stability at high speed.
• Fortified installation points: for strut-type suspensions, a thickness increase improves the strength and durability of the bracket attaching to the vehicle (steering knuckle) compared to OE shock absorbers.
• Fortified shell case made of a high-strength material with tensile strength around 150% of the OE shell case, with a bigger shell case diameter expanding oil capacity for improved durability and long-term stable damping force performance.
• High-performance damper oil exhibits a stable viscosity in a broad temperature range, has excellent anti-foaming properties, and is resistant to overheating and deterioration over time.
• TEIN-green powder paint coating on the shell case, applied with TEIN's patented 2-Layer, 1-Bake powder coating method with corrosion-proofing paint (Japanese patent number 4347712), for superior durability and rust protection.
• Can also be used with TEIN lowering springs.
• EnduraPro SP Kit is sold as a set for 1 car, combining EnduraPro dampers with the matching low-down springs.
