WP developments has put together a 68rfe tech article on low reverse sprags and how they work. The ends and outs of a roller type sprag vs a factory style sprag and why we use what we do with each build. Thanks for watching and please feel free to comment any questions below… I edited out some of the explanation because it did get to be a ramble, but one thing I wanted to make clear is the springs on the roller sprag are to make sure each sprag it held against the ramp to engage each one at the same time. If the spring is clasped they will not engage and cause the other rollers to be over worked.
