How does wheelbase affect shocks? All the Monomax shocks in the chart exclude my wheelbase (156"), yet Bilstein makes no such distinction. Can anyone provide an explanation? Thanks.
The straight-rail frame was used on commercial F350/450/550 cab/chassis (no pickup bed) trucks only.
All F250/350 pickups use the curved-rail frame. It does not matter which cab size or pickup bed length you have, the shocks are the same, for pickups, other than 2wd/4wd shock length differences.
