2006 Yukon xl with zw7 suspension

I picked up a 200g Yukon XL back in october. this is my first fullsize i have played with. it has the zw7 premium suspspension but seems like it does not have level but i may be reading sticker wrong. looking to change all 4 shocks as they look to be horrible shape. they are super scaley and dond have a single like of paint or any decals left. it is a north east truck. i wanted to run sachs. gm genuine or ac delcos for shocks prefer to match same brand/series at all 4 corners if possible. i do alot of long distance driving so trying to get truck up to *****.

this will get a lot of noise, but premium smooth ride is ZW7 and G65. you could put the sachs/nivomats on but would need softer springs.

lots of folks run bilstein 4600/5100 and send it.

so what your saying is since i dont have the g65 designation on my sticker is to convert to the nivomats and try to locate the proper springs to go with it? with the bilstiens from what i seen almost all the rears are requiring a new spring . i am looking to try and keep this simple with a straight swap of shocks.

if you had nivomat/sachs originally they need a stiffer spring to convert to a standard shock. conversely, it appears you don't have those so to change to them, you'd need a softer spring.

Front shocks are 540-201 or 88965472

Rear shocks are 540-433 or 25871225

Don't see too many on here with 4.10 gears, seems like a nice truck.

it has been pretty nice so far. those front shocks seem to be discontinued everywhere i look.

The RPO codes don't show G65, so this Premium Smooth Ride didn't have the Nivomats from the factory.
