Re: Driving on washboard.
We run 315's and RS9000's and drop pressure down to about 35-38lbs. I find the front to do 'ok' with the stock SMB springs... it's the rear that i can't stand. Our ass-end bounces around like an old cadillac.. with all the weight back there. The stock ford springs are way too overloaded..especially having a EB.. and deavers/alcans would help. The shocks probably need replacing/upgrading (size) too. I need to address this, but right now is the wrong time financially.
