Cal trac /mono leaf results

It looks like it could use more front end travel. Do you have at least 5" of travel (the Calvert recommendation), and 90/10 shocks? You might have to get the front lower to get the full 5", which is hard to get on a Mopar. Also, make sure the suspension is lubed up well (no binding).

Don't take this the wrong way, but you really can't say whats wrong when you change too many variables at once (preload, shock setting, launch RPM). Start with a baseline tune (like what worked the first time), then make 1 change at a time to see what the car likes best. It will take a little time, but at least you won't be chasing your tail. JMO.
