Question on replacement rear shock collapsed/extended length - 3rd gen

Hello,
Posted this in the Tacoma garage - Suspension forum, but you all seem to very helpful and faster to respond.

I have some 5160's on order getting delivered and will be installing them this weekend. I have a question on the change in collapsed and extended lengths between the stock oem 4600's and the new 5160's

Collapsed Length: 14.06" -> 14.22" (+0.16")
Extended Length: 22.90" -> 23.63" (+0.73")
Travel: 8.81" -> 9.41" (+0.6")

4600's: Bilstein 4600 OEM Shocks Rear for 16-23 Tacoma 4WD 6Lug
5160's: Shock

I see Bilstein advertises these 5160s as being a 0-1.5" lift compatible. I do not see how this can be if their shocks have only increased the extended length by half of that.

Also, for the increase in compressed length, is there anything I need to do to account for this 3/16" change so I don't allow the shock to "bottom out" (if that is the right word).

My truck is a stock barebones 2019 TRD OR DCSB for your reference.
