Wheel Hop

I think the "don't use slappers on a Mopar" came about only because mopars generally don't need them. Unlike Ford and gm, Mopar springs have a short stiff front segment for axle control, and a long rear segment for a soft ride. Super Stock springs have a stiffer yet than stock front segment. The purpose of a traction (slapper ) bar is to stiffen the front segment, so that it doesn't wrap up/unwrap when power is applied. The wrap/unwrap is wheel hop.
The usual fix is stiffer shocks, or slappers.
