ATI SR20 RWD Street Damper

The ATI SR20 RWD Street Damper is engineered to dramatically reduce torsional vibrations in the Nissan SR20 engine series, specifically designed for chassis models S13, S14, and S15. This high-performance damper ensures smooth engine operation and enhanced reliability by absorbing crankshaft oscillations that can compromise engine longevity.

Key Features

• Effectively eliminates torsional crankshaft vibrations for improved engine stability
• Meets and exceeds stringent SFI 18.1 safety specifications
• Precision laser engraved and etched timing marks for accurate tuning
• Durable black zinc chromate finish to resist corrosion and wear
• Power steering pulley sized at 11% underdrive to optimize accessory drive performance

The damper utilizes inner and outer shells made from either aluminum or steel, enclosing a steel inertia weight. This inertia weight features six grooves in the two-ring design or eight grooves in the three-ring design, which are computer-machined to retain high-quality O-rings. Each O-ring is carefully selected and dyno-tested to match the specific application, ensuring reliable and consistent damping performance.

Belt Sizes for Compatibility

• Power Steering (PS): 3PK855 (for S14/S15), 4PK855 (for S13)
• Air Conditioning (AC): 4PK880
• Alternator/Water Pump (Alt/WP): 5PK915
