Timbre s on 13 Silverado Duramax

[okiejoe]

Has anyone used Timbrens to aid in suspension but in turn did they inmprove harshness of concrete joints on interstate. I don't have a chucking problem just seems like rear axle action due to expansion joints

Yea my truck is a 3500 HD Dually, quite a bit different that a single wheel Tundra but I'm going to start with the bilsteins then maybe the Timbrens sense Timbrens say I could try and return if didn't workout. I don't have a sagging problem I have what feels like the duals are slapping harshly at each expansion joint in the concrete freeway.

Put Timbren's on my Ford to stop the squatting I had with my 5ver. Solved the problem and have not noticed a difference in ride harshness when empty. To me it worked better then bags.

I had them on my 2007 Tundra and did not notice any difference unless I went through a big dip where the suspension would want to bottom out. Then I could feel them make contact. Overall I never noticed them and certainly not when driving over expansion joints. Would buy them again if needed

My OEM shocks were done at around 25,000 miles-probably sooner. You will notice an improvement with new shocks but it will/may not solve your problem.

[okiejoe]

Yep, I think I'll start with the bilsteins 4600's my understanding is the 5100's are for 4 wheel drives or lifted trucks. Mine is stock 2 wheel drive

Bilstein 4600 made a big difference in the expansion joints and bridge transitions.

If you are just touching the overloads, then I would install the Bilstein 4600's first and see if that improves your ride.

[nevadanick]

I would say the harshnest is because your just hitting the overloads.

[rhagfo]

More spring will not solve a harsh ride, put a full set of Bilstein shocks 4600 or 5100 your choice!

IdaD, I've spoken with Timbrens and they said if I'm not satisfied I can ship the back for a full refund so if they don't help then no loss.

so IdaD, the harshness when traveling on concrete interstate with 5th wheel is less? Here is my thoughts, I have 65k on factory shocks and plan on replacing with Bilstiens and add Timbrens my dually doesn't squat very much, just enough to barely touch the overload springs to the stops for them. Truck carry load great it's just harsh on concrete. I also have the MorRyde hitch pin and TrailerSaver airride hitch just those dang expansion joints are rough.

I guess it depends on how you define harshness. It doesn't make the ride softer. Quite the opposite, it's a bit stiffer under load - but that eliminates the bobbing effect I would get sometimes when I hit significant bumps at speed with the fifth wheel. Bils are great, so start with those and see if it has the desired effect. If not, go ahead and try the timbrens too - they're only a couple hundred bucks so you're not out much if you don't like them.

I think the Bilsteins will help some, but agree with Grit dog, as to maybe lowering air pressure in rears to fit the load. If you already have proper pressure, then I think those darn cracks/joints...is what it is, using a DRW.

I don't think it will smooth out the hits from the pavement joints. They made the ride more harsh on my trucks but carry the load better.
If everything else is good like you say, maybe you can lower air pressure for your axle weight. Taller tires will roll a little smoother too.
