Rancho Shocks on Trail Boss

[KW 5226]

New here.  Question, does anyone know if the rear Rancho Shocks installed on a 2021 Trail Boss 6.2 are longer than the rear Rancho shocks installed on the stock Z71 without the 2" Chevy installed factory lift?  I'm asking because I am considering removing the factory installed 2" rear blocks to level my Trail Boss (instead of leveling the front).  Any help is appreciated.

The TB uses a longer shock than the Z71.

My buddy removed the 2" rear blocks on his 2020 AT4 to level - ended up adding back 1" blocks a few days later, but has had no issues since (8 months of driving and counting).
