towing ride
What causes a "bucking bronco" ride which is very hard to stop? Is it a throttle issue or a suspension issue or something else? This condition seems to start with bumpy roads and often at slower spe...

Adding air bags is just changing the spring rate with a second
set of springs. That changes the natural harmonic of the suspension
HD or higher PERFORMANCE level shocks with smart valving
For those who need to 'see' how harmonics works...go to a soft sprung TV, like
any 7K GVWR range with 'P' class tires
At a dealer, one out on the street (ya might get yelled at), or someone who
has one...
Push sideways on the rear bumper.
Notice how it springs back...and...then some...and oscillate a bit
side to side...to then settle down
Then do it again and again and again...matching the frequency it comes back
towards you...push when it just stops coming towards you and add to its travel
away from you
If you find and match it's harmonic...you can get it to jump over either way
off the pavement...or showroom floor...
That is its natural harmonic and the amount of force you have to exert is not
all that much...given you match its natural frequency
'Smart Valving' costs more and are there to provide 'ride quality' on normal
driving
'Smart valving' will have it sense 'the rate of change', or how fast the shock
piston moves
If it is moving FAST, it will open up to allow it to move fast...but once it
slows down...it closes that valve to reduce the movement speed (dampens it more)
That will null the proposing, but only so much it can do...you have to either
speed up or slow down to get the input bumps (tar strips, seam differences, etc)
to not be encountered in a frequency that matches your setups natural harmonic
Just know that going HD and/or Performance, will have the potential of reducing
your ride quality. If 'ride quality' is high on your have to have, then adjust
your speed as the main management metric
Ride quality is not on my have to have list and is at the bottom of my nice to
have list....most folks do NOT like how my trucks ride...but I love it that way
Have smart valving on my shocks and noodling adding a second set
(double shocks) to make it corner and handle better
Do know that I'm an old guy with a bad back too...
