Can you 'cryo' treat the entire Jeep? Just put the whole damn thing in there?

Yes, just move to Alaska in December
There's two types of deformation in steel. Elastic and plastic. Elastic is what your spring does every day. You apply a load, it deflects, you release the load and it returns. Plastic means you bend it.
The modulus of elasticity is the property we apply to this. For steel it's roughly 3x10^7 in/in/psi. Thermal treatments cannot affect this at all. That means for any given load it will follow this deflection.
What heat treatment does is increase the amount of load it can withstand before bending. Springs are very hard, so they can deflect under high loads without bending.
There's two more properties to consider. High strain rate and low strain rate. High strain rates are impact loads. Steel will behave different depending on a HOST of factors.. some from the steel making process.. some from thermal treatments.
That said. There's more that goes into this than one simple cryo treatment. Some people think it does help impact. For neutral hardened product with carbon levels below around 0.50%C, it will not increase strength at all. Under very special conditions for materials above this carbon level it may (if the original heat treatment was boggered up).
