The 5100s ride fantastic and the travel length seems to be more than adequate for my asphalt driving.
However, thinking back, this heavy clunk occurs each and every time I cross a dip or bump @ 15 mph+ and it seems to be isolated to the driver's side of the truck. It truly feels like something is being slammed into a frame rail.
Side by side comparison with the OEM shocks ...these 5100s are almost twice the length at full extension.
I was worried that they were too long.
I fully researched this torsion lift and shock part number before replacement.
I did not max out the lift on the torsion bolts.
My digital alignment results showed very minor
changes from the stock set up.
This clunk was not present immediately after lift and shock installation, did the suspension settle further a few weeks afterward?
Maybe I should back down a few turns and see if the clunk goes away?
