I appreciate your comments refer to leaf springs Tim but with coil suspension it is the damper's that limit travel, on full stretch at least and maybe full compression to avoid coil bind and/or physical contact with some part of vehicle. Given such the damper stroke does play a very important part of suspension travel.
Yes indeed, I was talking about the rear leaf spring setup. Your comments on coils are interesting, I always thought that coil suspension, especially rising rate systems used coil binding as part of the design to control the spring rate on bump. That's my understanding of how the SSL suspension is designed
