Mopar performance leaf spring.

The 268 is listed as XHD OE equipment (XHD = extra heavy duty)

The 864 is listed under racing springs, Super Stock springs.

I can not comment on actual ride height between the two or exactly how the compare with each other. Normally, the S/S springs ride high.

I do believe the OE XHD Springs are they ones your looking for with a slight over bend for a nice rake.

I went to ESPO.com for my springs and order the 6 leaf @ a 1 inch over bend.
