What causes Highway Float?

[Rammer]

Hi,

I have a 2005 stock GM GS and I want to upgrade the shocks and probably the springs to eliminate the highway float and "inspire confidence".

My car has a stock front sway bar, but not rear.

I have gathered that I can use the Marauder springs and shocks up front. However, I have stock springs in the back and I'm not sure if just hd shocks and an swaybar will be enough.

Thanks

Just replacing the shocks will fix your float. I have worked on a lot of town car with the same feeling and the shocks repaired the ride. For the rear end it is up to you. A swaybar will help with body roll.

Springs and stabilizer bars will help, too.

What is a 2005 GM GS?

Model Year: 2005

Vehicle: Grand Marquis

Trim Level: GS

----------------------------

BTW, agree on the shocks, go with Monroe Severe Service, also a rear sway bar will cut down on body roll.

PM 03mmmonroe to see if he still has m old OEM sway bar, and if he doese, see if he's willing to sell it.

Why not just buy the kind of car you want it to float like. :confused:

SC Cheesehead,

Are you saying use Monroe severe service on all 4 corners or just in the back and Marauder oems in the front?

Thanks

CBT,

I didn't buy a Maruader or CVLX Sport because they; A) have a center console-I need to seat 6, B) Have worse gas mileage, C) Marauder takes premium, D) Are more expensive, and E) I got a deal on this car.

I am just trying to adjust the current "grandfather" suspension characteristics.

I've got Monroe Severe Service on all four corners, and upgraded to a HD rear sway bar; car handles very well now.

Ride is very firm, but not harsh; no rolling in corners.

All GM will "float" that is how are set up from the factory listen to member in post #2 and will not be sorry. Trust me I know first hand:)

Thanks SC Cheesehead. I am wondering if I should use the Marauder springs up front or switch over to Crown Vic P71 Interceptor springs instead. I've read they are similar in rates.

I noticed you're in Greenville. I went to Clemson, but am locked in Boston now.

Ah, you know the area, then! Clemson's a good school, we've got a lot of their grads working here at Fluor.

Suggest you PM gdmjoe, he's an expert on all things CV, 03mmmonroe may want to chime in on the subject as well.

I installed KYB shocks on all fours and I don't feel much of a difference on my 99 GM. They helped with body roll a little and helped with the float just a tad. If I'm fully loaded with people, my x pipe will scrape only when I float. . Wish I had known about the Monroe shocks recommended here. My next step was to go with new springs.
