What exactly is included in A35 HD trailer towing package

[70pumpkin]

My Challenger has the A35 option which is described as follows:
      Trailer Tow Package (A35, N/A w/440+6 or 426 engines)
      Max cooling system, HD brakes w/auto adjusters, HD suspension, HD turn signal flasher and stop lamp switch, HD wheels, HD performance axle (3.23 ratio). 

My car has a 26-inch radiator (max cooling), power front discs (HD brakes). 

What I don't know is what is meant by HD suspension, HD turn signal flasher, HD wheels (I have 14-inch rallyes), and HD axle (I just have a 741 casing).

Does anyone know the details?

The HD suspension should be the Hemi suspension.  Do you have a build sheet for your car?

[70pumpkin]

Hemi suspension would be great!  Unfortunately, I don't have a build sheet.

It may just mean the 383 R/T suspension though. Build sheet will nail it down by the part #'s.

Do you have the original leaf springs on the car still?

Thanks!  I think the car came with a smaller front sway bar which has since been replaced with a bigger one.  It never had a rear sway bar.  Leaf springs were replaced with the same type from ESPO.
