2001 F-150 Ride Quality

Recently put new Michelin LTX 245 70R 16 tires on the truck. The truck also have relatively new shocks, Monroe Sensa-trac's. I don't know if it's the combination of the two or there is something else at fault, but the ride quality is terrible! The suspension action is virtually non-existent. The truck just rolls with the bumps and irregularities in the road. I have checked for any binding or other worn components in the front and everything looks ok. No worn tie-rod ends, ball joints, etc. Any ideas?

You don't mention if the ride quality has changed since you installed the tires. First thing to do is check tire inflation.

35 lbs. as prescribed by the manufacturer.

Put oem shocks back on it. Some times stock is better.
