Porpoising Bluebirds

David and Brad:

I have been following your posts on this subject and found your
results very interesting. I worked in a huge truck chassis/spring
shop in my youth. Of course in those days rauckers were macho and
never complained about anything ! Hear that Greg?? One thing I did
learn about pickup trucks was that good shocks ere very important. We
sreviced trucks that went to the oil fields and front suspensions
were always being repaired. he Monroe rep had special shocks built
for these units. My own experience is as follows: factory shocks on
just about any vehicle are usually cheap junk. In 2001 I had a new
Chev Duramax duallie crew cab. We had a 11.5 Alepnlite slide in on
the back. It handld horribly. I dropped the rear shocks and you could
compress them with one hand. Extension could be done by a child.
Naively I took it to the deAler thinking they were faulty. Shop
foreman brough out a new shock. We pumped it a bunch and it was the
same. Installed 4 Rancho 9000's and it became a new truck!! Last year
I took off he Sachs shocks that were factory on our 02 Bounder with a
Freightliner. The shocks looked small enough to be from a Nissan
pickup. Installed new Koni FSD's and I could drive without white
knuckle fever. My point of all this jibberish is: Have you considered
installing different shocks? I dont know what BB uses on the LXI's
but maybe they are not enough shock. I know that Henderson had some
real brutes at Q. Of cousre they were pricey. Once a vehicle starts
porpoising the dynamics just keep it going. Sems to me that som real
shocks would solve the problem. I now that BB uses Konis on some
units but the FSD's are fairly new to the market. Alternatively have
you tried going to Henderson,s? I find them overpriced but they are
experts.
