Background about where the DSSV shock development came from, and a little about why they use spool valves instead of orifices to restrict oil flow.

I meant in the picture above. They are the two rectangles between the lower strut and the leaf springs. 
 

These are actually the ZR2 specific leaf spring insulators.  You can get a better view here https://www.rockauto.com/en/moreinfo.php?pk=13661621&cc=3450532&pt=13637&jsn=1907 If you dont have an AT4 or trailboss you HAVE to buy this PN as well: 86814402

Just trying to figure out why?  What’s the TB kit get you that you need other than lift blocks?

Im guessing the brackets they show. The electronic re-cal is probably pretty important too. This truck at the limit definitely has a ton of electronic intervention to keep it planted.

Meh. I’m the same height as a TB or AT4 with taller tires. Aligned as a TB/AT4. Handles and drives fine.

 

Not sure why you’d need the TB kit too other than $300 worth of CV shafts you can buy at a parts store and less than $200 worth of lift blocks.

Pretty sure the rear springs are specific to the ZRX package. Yea im sure under normal conditions it wont matter, its in emergency maneuvers that the brake/steering/throttle nannys would act slightly diff.

 

You can def put together this kit cheaper if you know where to look.

Rear leafs are softer rate which is why the ZR2 has less towing capacity than the same 6.2 equipped Trail Boss.

I believe its the springs and diff hardware that give the additional travel in the rear.

I drive 400+ miles per week year round. Emergency avoidance maneuvers have been done. The “reprogramming” sounds like mostly BS so GM can convince folks to pay to have them install the kit and then reprogram the speedo. 

 

The softer rear springs are nice. I bet the Deaver packs are still cheaper.

Don't worry about the facebook market place ad. I think I know where they're headed.

I found two fronts in a junkyard, still looking for two rears.

Sounds like a square deal to me.
