TiAL 002475 MV-Series Replacement Wastegate Spring for MVS & MVR

The TiAL Sport 002475 is a genuine replacement actuator spring designed for use with TiAL Sport's MV-Series external wastegates, including the MVS 38mm and MVR 44mm models. Sourced directly from TiAL Sport, this spring maintains precise boost pressure control in high-performance and motorsport turbocharger applications.

Key Features:

• Manufactured from 17-7 PH Stainless Steel for consistent pressure delivery at elevated temperatures
• Resists spring "relaxation" at temperatures up to 900°F (483°C), ensuring reliable boost control under sustained heat
• Compatible with TiAL Sport MVS 38mm and MVR 44mm MV-Series wastegates built after January 16, 2012
• Not compatible with older-style TiAL 38mm, 40mm, 44mm, 46mm, or 60mm wastegates
• Springs can be nested in combination to achieve higher target boost pressure levels — total resultant pressure equals the sum of individual spring ratings
• Genuine TiAL Sport USA-made component

When targeting specific boost levels, multiple springs may be used together in a nested configuration. Always reference TiAL Sport's official spring pressure chart to select the correct spring or combination of springs for your target boost pressure. TiAL Sport has updated spring colors on MV-Series springs; spring characteristics and dimensions remain unchanged across color revisions, and old and new color springs may be mixed to achieve target pressures.
