Are the SS and Police Car suspensions the same?

Just wondering if the SS and the cop cars have the same suspension parts or not?

Yes and no. They should be the same FE3 suspension, but cop cars usually have a little beefier suspension. Does that make sense?

the front springs are beefier on the 9C's the rear springs and sway are the same. if you want a bigger sway for the front go with the dorr man kit to replace your 20mm solid front sway with a 33mm solid front sway then the other options are strut tower braces

I know the ride height is higher on the 9c1, and 9c3. I would think it is all 4 springs different but don't know for certain.

I've been trying to figure this out too. I had a GM rep run a build sheet on a 2012 9C1, suspension code was 7B3.
The 2012 LTZ suspension is FE3, LT is F2, LS is F1. Wish I'd linked the source of that info. I'll go look for it.
According to the 2012 Impala dealership brochure, the LS & LT have "Touring" suspension and the LTZ has "Luxury-Tuned." Whatever that means.

The LTZ's bars are hollow, 34mm front and 18mm rear.

You know it isn't the 70s anymore the old blues brothers comments really don't hold true anymore.

9C1s are built CHEAP more than they are HD. It doesn't really pay to have separate R&D to make something "special" for cheap fleet sales units.
Yes they are generally taller for curb clearance and such but such things are not big or substantial upgrades. Then there can be things that would be wrong for a DD car. On the 6th gen cars the 9C1 got an oilcooler that did not regulate temp just blindly cooled, fine for a car that idles with the AC on in a median for 8 hours but for a driver the civilian setup that REGULATES oil temp with the coolant is a much better idea.

Point being tell us what you want and then folks can advise on how to get there.

I was wondering this too, because I'm thinking about buying the monroe quick strut police package on my 2006 Impala LTZ and I'm wondering if it will fit, just a little higher off the ground?

Yes the "police taxi" struts are 1/4" longer than the others but their "travel length" is shorter.
Here are specs;
171670 ( Police/Taxi/W 17" wheels incl LTZ)
Body type: B9
Body Length: 10.00
Compressed Length: 10.500
Extended Length: 15.375
Travel Length: 4.875

171661 ( all others )
Body Type: B5
Body Length: 9.750
Compressed Length: 10.250
Extended Length: 16.625
Travel Length: 6.375
Requires a parts pack P588 although not certain what's in this package. The 171670 apparently does not require one.

I'm definitely getting those monroe quick strut (police package) now. I think that will be a nice Christmas gift for my Impala.

It would be nice if Moog made a Problem Solver Control Arm. I would love to just bolt it on, instead of pressing bushings and drilling out ball joints.
