All springs are current and the “oldest” spring we have in stock was made in December 2019.

For the ENDURO line, the lengths of the springs vary between 105mm-115mm depending on rate as the diameter of the wire determines what length a spring needs to be in order to actually perform the declared rate. All SAR springs are tested for accuracy, linear capability and are race proven year after year.
