TiAL 002408 Wastegate Replacement Spring 17-7 PH Stainless Steel

The TiAL 002408 is a genuine OEM replacement wastegate spring engineered for use with TiAL external wastegates. Manufactured from 17-7 PH stainless steel, this actuator spring delivers consistent, repeatable boost control while resisting spring "relaxation" at temperatures up to 900°F (483°C) — well beyond the thermal demands of even the most aggressive forced induction applications.

Wastegate springs are the foundation of base boost pressure control. The spring rate determines the pressure at which the wastegate valve begins to open, establishing the baseline boost level before any boost controller input. Selecting the correct spring rate is essential for tuners dialing in precise boost targets across motorsport and high-performance street builds.

Key Features:

• Genuine TiAL OEM replacement spring — ensures proper fit and performance
• Constructed from 17-7 PH stainless steel for consistent pressure under extreme heat
• Rated for sustained temperatures up to 900°F (483°C) without relaxation or pressure loss
• Color-coded for easy identification and spring rate selection
• Compatible with TiAL external wastegate models — verify fitment against TiAL's spring chart for your specific wastegate
• Springs can be nested in combination to achieve higher base boost pressure targets
• Sold individually

TiAL wastegate springs are color-coded by pressure rating, and multiple springs can be run together in a nested configuration — the combined resultant pressure equals the sum of the individual spring ratings. Always reference the official TiAL spring pressure chart for your specific wastegate model (F38, F40, F41, V44, F46, V60, MV-S, or MV-R) to confirm the correct spring selection for your boost target.
