Tow Group Spring Q?

[Magnetrt]

I've vin'd a few vehicles to determine that different springs definitely come with the Tow Group.

My quest is to ask if the specific difference has been determined between Tow Group Springs and non-tow group springs and what that is?

Thanks

After lots of reading I'm convinced that the Tow group springs are a bit lighter in spring rate. Making for a better match to the Nivomat shocks. Stock R/T springs will probably sit too high with Nivo's installed.

You got it right. Putting the Nivomats on stock R/T springs will lift the rear about 3/4".

I ran that combo awhile thinking if I really loaded the rear it would be a good thing. Filling the wagon with cases of water barely droped it at all!

I think I have a set of the Nivo shocks and springs, if I can figure out which is which.

Spring height is the same, just the spring rate is softer on the Nivo rear set up.
