I got some free 3 inch lift springs for the rear of my sammy and I am curious how well they will flex as compared to non extra arched springs? As it is I will probably run spring under on the rear due to how much they arch. Appreciate any advise the more experienced can offer.

Any advise?

A flat spring will flex better than an arched spring ........ all things being equal except the arch

So will a flat spring reach/flex further down than an arched spring or will the arched spring still reach as far but not need to flex as much?
