SMOOTHER RIDE?

something is perhaps keeping the suspension from doing its job.

because your choice of components would be on the list for update / rebuild for a lot of us....I would ask if you maybe over tightened the U -bolts on the rear causing binding. Also, was the front tightened in the proper sequence /correct specs.

when you push downward on the front and rear....does it move freely?

you did not mention it....but what size tires /rims do you have?
