Not Ranked
Tim and Terry, Thanks for the response.
Well, I don't want to start an argument here.
If your shocks are angled, then you are not getting a 250 lb spring rate from your 250 lb springs.
I contemplate reworking the 2 x 2 frame rails behind the rear axle, to one accommodate a steel can fuel cell, two to relocate upper shock mounts, about 2" further outboard. Replacement of shock mount on axle, and thus these rear shocks will be vertical, so actual spring rate will equate to actual load on axle. I kind of guessed that 150 rate spring should be adequate for the rear, "IF" there is adequate shock valving. That is why I want to know how much preload compression the springs have from free height to ride height, from someones use of a specific spring. I would like to be able to have control over 6" of shock travel, without losing spring travel.
So if someone has an FE motor in their snake, please weigh the axle loads for me.
One other thing I am doing, is building a lower "A" frame lower control arm, and junking the stock control arm and strut rod, from the must. II front suspension, for free suspension travel, no strut rod bind. Better steering stability. The upper coil over shock mount here will also be moved outboard as space allows.
Thanks for your input.
Gerald
