DeDion Rear

[E90400K]

If Slate wants to use as much part commonality as possible, why not just go struts all around and use the same suspension front and back? Use a suspension link in place of the tiered for the rear hubs. An IRS should easily handle a 1,400 pound payload.

Pickup box intrusion maybe?

Depending on how it's designed, a De Dion suspension could use the same struts as the front suspension.

That article doesn't address the question.

This would be a poor design for a few reasons, most obvious to me is the camber curve when the truck is loaded.

Also You would also get bump steer in the back, which would be sktecy. You would also have a weird axis of rotation that would be flat if both front and rear matched, then as the roll center moves around during braking and cornering the tendency to oversteer or understeer would randomly switch depending, the truck would be super unpredictable.

Slate would need to add features to the strut for it to mount and pivot through its rage of motion, on the front it would be fixed to steering knuckle and on the rear the lower mount would need to pivot. Then you would have a different spring rate for the rear, so you would need different shock valveing, also it would be a waste of engeering to try to match the packaging... I think different shocks f/r is the correct approach to save money.
