The Deathright Silo in Borderlands 4 is located in The Low Leys in the Terminus Range. Getting to it will not be easy, given the landscape, but if you're looking to acquire SDU (Storage Deck Upgrade) Tokens, this is one way to do that. There won't be many enemies to deal with on the way to the Deathright Silo, but you will need some slick moves to get to the location.
Here's how to get to and unlock the Deathright Silo in Borderlands 4.
Where to find the Deathright Silo in Borderlands 4

The Deathright Silo is in the Terminus Range towards the northern part of the main region. Substation Canonary (sub-region) is your starting point. Look for the frozen waterfall, and start making your way up the hill. The image above shows your starting point.

Keep going up the slope until you cross the frozen waterfall and see a grapple point. You will have to walk quite a bit to reach it. Grapple and make your way to the top of the hill, walk past the structure (keep to the left), and keep going until you reach a ledge.

Once at the ledge, jump and glide towards a metal wall on the far side of the ridge. Try not to botch the landing, or you will have to start over again. Once atop the ridge, move forward until you see a ramp.

Jump off it and glide to the other side, and start scaling up until you reach the Kratch Nest. Kill or ignore them, and make your way to the structure at the very end of the pathway.
How to unlock Deathright Silo in Borderlands 4

Once you're inside the structure, activate the terminal, and you will have unlocked the Deathright Silo. This will give you an additional Fast-Travel point to make use of while exploring Kairos. Keep in mind that getting to this Silo is a process of trial and error if you're not good with mobility, but it will be worth the time and effort.
