Porposing on concrete highways, Bilstein worth the $

I put on the Bils at 100k miles. Could not really tell. Next set will be Monomax.

I run 5100's firm, solves 99% of the chucking on my rig. I drove about 6 miles of a old concrete road that had been chip sealed, could feel the bumps, but no chucking.

Hi can anyone recommend which blistens to use on a 2004 F250 CC V10. Thanks

x2 on weigh, tongue, +road conditions will do it. Bilstien will help

Have you ever weighed the trailer and TV. What is your tongue weight percentage? Is the trailer level? Low tongue weight and nose high can cause Porpoising.

I replaced my stock shocks last week on my 12 Ram 2500. I had around 12,000 miles on them. I replaced them with Bilstein 5100's. I also have a MorRyde pin box on the 5'er. Long story short, towed with just the MorRyde pin box 1st. It helped somewhat. Just towed 200 miles with the MorRyde and new Bilsteins and the shocks made a big improvement. Roads were freeway all the way with a mixture of asphalt and concrete. Some of the concrete was pretty bad too. Bit the ride was fairly well controlled.

I never changed the PSI in the tires from the last trip. They are at 75r, 70f. I drove around some before this trip and the truck empty feels as good as when I air down the tires to 45r, 65 front. Overall a great improvement IMO.

FWIW, I have replaced the stock shocks on my last 2 trucks with Bilsteins. They are a huge improvement. On my current 2011 Chev 3500 I replaced the rear shocks at less than 10000 miles... and also added Timbrens at that time. I found a huge improvement. I just replaced the fronts this week with Bilsteins at 20000 miles. Have not towed yet, but at 20000 miles they were toast. Now, I do have a plow that I use in the winter, but don't leave on when not plowing.

The bottom line is that your shocks are well past needing to be replaced. You will have a much better towing experience when you change them out.

There are certain sections of I-75 south of Atlanta I get the porpoising too. Makes no difference if I have full tanks or empty. Really annoying. It was really bad when we went out west through Oklahoma on I-40. I pulled over thinking something was wrong. When the pavement went back to asphalt it went away. I seem to get mine when I travel on concrete surfaces.

I have Bilsteins on our truck and our trailer has shocks on it also...on certain roads like I-5 through Tacoma-Seattle I get some bounce/porpoising...

I think it's just the road..it's the only place I get this. Normally our rig runs nice and smooth..I just slow down and it seems to help some.
