Question about assembled Bilstein 6112 front struts

[Dlarimer57]

From what I have read about these, they come fully assembled but the instructions say to compress the spring and install the dust boot from the OEM struts. Is this really necessary? Seems like it defeats the purpose of buying them already assembled. Thank you those that can give me some insight to this.

 

Looking at ordering the front and rear Bilstein kit soon. My truck is a 21 Elevation crew cab 5.3 w/ X31 package 275/60/20

 

With the Bilstein 6112 at full length raising the front 2.5" would I be able to fit a slightly bigger tire? Would I have to replace the UCA?

looking at 275/65/20 or 285/65/20

Unless you are getting them from a shop that provided a fully assembled strut you are going to have to pull the dust boot and top hat assembly off your old struts, so you're going to have to compressor the old stuff off and then compress to the new to install them yourself or at a shop to complete the assembly.

Looks like you are all set with that complete assembly. I installed the 6112's on my '20 AT4 but didn't get them fully assembled and did the swap myself and wasn't too bad. They are a very nice setup vs. what was on from the factory, I changed mine out @10,000 miles, and have the 5100's out back.
