Uprated Small Spring (Single)

These are the individual springs sold in our FMTVTUN kit. Please select the colour you require using the options above.

Valve Spring Colour Coding: The weakest spring is GREEN, followed by YELLOW, BLUE, RED, and WHITE which is the strongest. Depending on the supplied original fitment, this represents an increase of 25%, 50%, 75%, 100%, and 125% respectively.

The standard spring option is for customers who wish to replace a broken idle spring in their twin piston atmospheric dump valve.
