Regarding putting in the rear sway bar -do you feel the rear sway bar helped stabilize your truck over rough roads or helped the truck to ride more smoothly? I have a Heidt's front end & sway bar but my 1951 Chevy 3100 5 window still jumps right or left on the fwy at 60 mph on rough patches. had a recent alignment & running low profile tires. how yours ride?
