Tial Wastgate Springs for F & V Style WG's

Genuine Tial wastgate springs.  These springs are used with F38, F40, F41, F46, V44, V60 wastegates.

These springs allow you to customize your Tial (or Tial-style) wastegate to perform exactly as you wish. Springs install easily with simple hand tools.

NOTE: Spring pressure is dependent on which wastegate you are using. Please see the charts below to determine which spring(s) you need for your application. Higher pressures than the ones shown in the charts below are achieved by combining one large and one small spring together in the same gate (they're sized to nest together perfectly). Simply add the two spring values together to get the resultant spring rate.
