This will potentially affect the ability of the car to hook up if you don't run a traction device because you are extending (read weakening) the front section of the spring.
you say weakening and i say traveling allowing more movement to be useful for traction. one big issue with mopar is the front section is short not allowing enough wrap up to be useful with traction bars. remember mopar designed these to run with a snubber back in the day. so they didnt want wrap up of the leaf. in todays world wrap up is leverage against the tire with a traction bar. the longer the front segment the more leverage that can he applied with a traction bar as it attempts to wrap itself up. i also will only attempt to see how this works once or not at all before buy monoleafs with the pin where i want it. after all my setup is of higher power than most will ever be shooting for.
