    Default new shocks but ride still sucks....

    Hey All,

    I need some advice...

    I installed some Bilstein 5100 shocks on my 2003 2500HD, the old shocks were stuffed when I pulled them out and once compressed would not extend again, but once I put the new shocks in I was hoping it would fix the issue I had which is....when going over some bigger speed hump the front end seems like it just drops/bangs down....

    I dont know if thats just normal for a truck or if there is something else that needs tro be changed... I tried with the torsion bars at normal height, cranked a little bit and cranked a lot and didnt seem to make much of a difference....

    HELP.....

    If you crank your torsion bars it will only make your ride stiffer. Also, if you have a tire with a relatively aggressive tread pattern that will have some negative effect on ride quality also.

    The tires are BF Goodrich all terrain T/A's.... How are they for ride quality?

    I did put the torsion bars back down so that the lower bump stops are just off the lower control arms....

    Maybe I was just expecting too much from the Bilsteins...... from thread searches people talk them up like they are fantastic, thats why I am thinking maybe there is something else that needs replacing....

    They ARE fantastic!I found that once i replaced my stock 245 tires and switched to 265s the ride softened a great deal.I'm running my Goodyear Wrangler Territorys at 45 psi.The tires are load range E and and are a mud & snow tire.I ran Firestone Transforce Ats before at 35 psi

    that might help, but the BFG A/T TA's should ride fairly smooth.

    As far as the bang when going over speed bumps, have you looked at the upper and lower control arm bushings? Your truck is about 8 years old and those bushings may be cracked and worn.
