These are used springs purchased from Texas Speed a couple of years ago, they have at least 30k miles on them. They were recently checked out by a local machine shop and they all tested 125-130 lb closed and 340-345 open at 0.600" and were all within five pounds of each other.

This includes the dual springs, titanium retainers, spring seats, and locks.
