torsion bar lift .... now I have a clunk
 
I cranked my torsion bars to give a 1.75" lift.
I installed Bilstein 5100 24-185776 non adjustable front shocks (these things are soooo much longer than the stock shock, yet they claim to apply to 0" - 2" lift).

I now have a hard clunk in the driver's side front suspension, which I can feel in my butt and in my feet, when riding over a speed bump or a moderate dip in the road. Sounds and feels like something is banging against the frame.

I installed new sway bar bushings (old one were dead) to fix the clunk, which seemed to tone it way down for a few weeks.
Now that it is frigid outside, the clunk has gotten worse.

Do I need to install adjustable end links to accommodate the longer travel of the new shocks?
Maybe I have a dead shock?
Or a worn end link?
OR ... is this something I need to look into?
Use on trucks with up to 2.5-inches of suspension lift.
Compression bump stop on chassis may need to be modified to prevent damage to the shock absorber. This is standard when placing longer shocks in the stock location.

The bumpstop should be foam so I don't think that it. When do you hear the clunk/thud, on the rebound or compression of the suspension?

compression of the suspension

Are you sure? When you increase the torsion bar preload you are only changing the ride height. So the suspension is closer to being "topped out" than "bottomed out". A lot of times people put too much preload on the torsion bars and get a "clunking" noise when the suspension topps out when rebounding over bumps.

I say check where your shock is connected to the shock tower. I know i have read somewhere on here about the nuts holding the shock in place backing off or being cross threaded. Just an idea i hope you can figure it out!

Collapsed Length 14.88"
Extended Length 24.37"
Travel Length 9.49"


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?

I have the same issue. I had them only 2 weeks. I thought maybe there is a break in period. I'll be in touch if it gets better or worse.

any new info on this clunk situation?

did you install the bilsteins correctly? There are multiple reports of people installing these shocks and not putting the components on in the correct order which causes a clunking

Timbo114 04-27-2013 10:43 AM

There is only 1 way to install this shock using the parts supplied.
So Yes, I installed them at the stem in this order,
seat-bushing-mount flange-bushing-seat-nut.

I had searched extensively before this purchase, and this #24-185776 is the one used in all the posts I read on all the RAM forums I could find.
Can anyone here confirm 100% that I have the correct part #?

Or is this shock actually too long for my application with 2" torsion lift?
