Smoother Ride

Well here it is in her own words quote: “The aftershocks are gone and my body don’t jiggle no more! The ride is 50% better than what it was, it’s not my old Suburban, but we’ll keep the truck” ,unquote. The receiver hitch had to be lowered to remove the shackle bolts, and the torsion bars were adjusted up 1/4″. The front is +1″ higher and the rear is +5/8″ higher. At the suggestion of the installation tech I changed the tire air pressure while riding empty in the front from 55# to 65# and in the rear from 65# to 55#. The engine is where all the weight is and the bed is empty, it was visible in the tire sidewalls as he pointed out to me. Back up to 80# when towing. I drove the truck and was quite surprised at the big difference, especially after reading on the forum about all the big bucks spent on shocks and other suspension type items. I was skeptical to say the least, but now I am sold! Here is a link to the installation pics, read the inital comment for more information when you get there. Monty

Update:

The springs are doing what they claim to do. I pumped up the air in my tires front and back (80#)to tow my TT home after some dealer warranty work. The trip was about 30 miles and I as presumed, the ride was fine because of the heavy tongue weight. What I did notice was after unhitching and going for a ride to grocery shop was that the additional air in the tires made the ride considerably rougher. So the best pressure for us to obtain a smooth ride is 65#F and 55#R. These springs are fine if you run empty most of the time, they would be less valuable if towing or carrying a load most of the time. Overall the DW is happy with the ride, and that is what this was all about in the first place.

Everything is still right on, not one problem or disappointment! We took a 300 mile trip on the 19th, 80% freeway driving at 70mph, the rest on meandering mountain roads and without provoking her the DW blurted out about how much she was liking the truck now since the ride was so smooth. Music to my ears! Tire pressures make a difference, as mentioned earlier I am running 65psi F and 55psi R when empty. Mileage on this trip (no towing) was 18.65 mpg. I would not hesitate to do it all over again, it has been worth it.

Tires and shocks still stock. No other changes, have about 7,000 miles now. It was a wise move for my situation. I did not need to upgrade the shocks to smooth out the ride and when the little lady is happy, I am happy!
