Order Silos in Borderlands 4 are essential structures that provide fast travel points, reveal Vault Fragment locations, and reward players with 40 SDU tokens each. There are 9 Order Silos total across three regions: Fadefields, Terminus Range, and Carcadia Burn, with completing all of them unlocking the Balloonacy Challenge and earning 360 SDU tokens.
| Order Silo | Region | Sub-Zone | SDU Reward | Key Feature |
|---|---|---|---|---|
| The Stockroom | Fadefields | Coastal Bonescape | 40 | Easy access from Abandoned Post |
| The Kit Hole | Fadefields | The Howl | 40 | Hilltop location west of Launchpad |
| Deep Seven | Fadefields | Dissected Plateau | 40 | Requires grapple point access |
| The Reliquary | Terminus Range | Cuspid Climb | 40 | Mountaintop past Hollowhome camp |
| Covered Charge | Terminus Range | The Low Leys | 40 | Gap jump required for entry |
| Deathright | Terminus Range | The Low Leys | 40 | Confusing map icon location |
| Rustical Hurl | Carcadia Burn | Grindstone of the Worthy | 40 | Cave entrance or plateau glide |
| Site Unseen | Carcadia Burn | Tonnage Peel | 40 | Northwestern road endpoint |
| Judgment's Lapse | Carcadia Burn | Ruined Sumplands | 40 | Vehicle boost jump needed |
I've spent countless hours exploring Kairos, and Order Silos have become my favorite discovery mechanic in Borderlands 4. These towering structures are remnants of the Order's surveillance network, now waiting to be hijacked by the Crimson Resistance. When you first approach one, you'll notice they're heavily guarded by Order forces or other hostile factions - but here's the secret: you don't actually need to clear out all the enemies.

Each Order Silo serves multiple critical functions that make them absolute must-finds for any serious Vault Hunter. Once activated through the console interaction with ECHO-4, these structures become your gateway to efficient map traversal and treasure hunting. The surveillance balloon that launches from each captured Silo isn't just for show - it provides a grapple point that lets you zipline up and glide across vast distances, making exploration significantly faster.
The most valuable aspect? Each Order Silo reveals the approximate location of a Vault Key Fragment in its sub-zone, marking a glowing radius on your map where these precious collectibles hide. Without activating the Silos, finding all three Vault Key Fragments needed to unlock each region's Primordial Vault becomes a needle-in-a-haystack situation.
Every Order Silo you liberate rewards you with 40 SDU tokens - that's 360 tokens total across all nine locations. These tokens are crucial for upgrading your backpack capacity, bank slots, lost loot machine storage, and ammunition capacity for all weapon types. In my experience, prioritizing backpack upgrades first gives you the best quality-of-life improvement, allowing longer farming sessions without constant vendor trips.
Order Silos function identically to Safehouses as fast travel points, dramatically improving your mobility across Kairos. Unlike standard fast travel stations that only appear in major settlements, Order Silos are strategically placed throughout wilderness areas, cutting down travel time when farming bosses, completing side missions, or hunting for collectibles.
Each Order Silo houses multiple vending machines including weapon vendors, ammo dumps, and health stations. The Item of the Day often features useful gear at discounted prices - I've found several legendary weapons this way. The vending machine types vary by location, so hovering over the Silo icon on your map shows which vendors are available.
Claiming all nine Order Silos completes the Balloonacy Challenge, rewarding you with an exclusive vehicle cosmetic skin, substantial XP gains, cash bonuses, and a generous Eridium payout. This challenge contributes to the "Ruler of Everything" trophy/achievement, making it essential for completionists.
Difficulty: Easy
The Stockroom is likely your first Order Silo encounter, positioned northeast of the Abandoned Post Safehouse. From the safehouse, follow the dirt path upward, dealing with or bypassing the Synth enemies patrolling the area. The console sits at the top of the enemy camp - a straight run up the steps leads directly to it. This location serves as an excellent introduction to the Order Silo mechanics.
Pro Tip: Use the elevated position after capturing to scout for nearby loot chests and Dead Bolt locations.
Difficulty: Moderate
Located west of Launchpad Faction Town, The Kit Hole requires navigating uphill terrain. Mark it on your map to activate the location path guide - you'll need to ascend the mountain's side and cross a wooden bridge. The enemies here are more aggressive than at The Stockroom, but the circular arena layout allows for kiting strategies if you choose to fight.
The vending machines here often stock shock weapons, perfect for the shield-heavy enemies in the surrounding Howl region.
Difficulty: Moderate-Hard
Deep Seven proves trickier than its Fadefields siblings. Head to the northeastern section where the building icon appears on your compass. Don't approach directly - instead, move left to locate the grapple point. Latch onto it and climb the metal grates to reach the interior. The vertical approach catches many players off-guard, as the ground-level entrances are sealed.
Once captured, Deep Seven's balloon provides exceptional gliding opportunities across the Dissected Plateau's canyons.
Difficulty: Hard
Positioned in southern Terminus Range, The Reliquary demands mountaineering skills. Navigate past the Ripper camp called Hollowhome - you can fight through or use vehicles to bypass most enemies. The final climb to the mountaintop console requires careful jumping and mantling. Winter weather effects can obscure visibility, so I recommend attempting this during clear conditions.
The Vault Fragment revealed by The Reliquary often spawns near frozen waterfalls, so pack cryo-resistant shields.
Difficulty: Moderate
Covered Charge's location seems straightforward on the map, but accessing it requires following specific ridge lines near the riverside. The building icon appears as you approach, but you must wind around following the natural terrain. Eventually, you'll reach a gap requiring a running jump - miss it, and you'll need to circle back around. The interior houses level 15+ enemies on normal difficulty.
Difficulty: Very Hard (Confusing)
Warning: The map icon for Deathright is misleading! It points to the silo structure releasing the balloon, not the activation console. The actual console sits on the mountain north of the map marker. From the incorrect silo icon, circle west around the mountainside until you find a climbable wall. Scale it, then traverse the cliff edges to reach the console at the mountain's end.
This confusion has frustrated countless players - I spent 30 minutes searching before discovering the correct path. Follow the red path markers if you've placed a waypoint, as they lead to the proper location.
Difficulty: Easy-Moderate
Rustical Hurl offers two access routes. The ground approach requires entering through a cave at the plateau's base - follow the tunnels upward to emerge near the console. Alternatively, if you've unlocked vehicles with boost capabilities, drive to the plateau's top and glide through the opening directly into the control room. The aerial approach skips all enemy encounters.
Difficulty: Easy
The most straightforward Carcadia Burn Silo, Site Unseen sits at the end of the main northwestern road. Simply follow the winding path, sprinting past the bandit ambushes if you prefer avoiding combat. The terminal waits at the road's terminus - a 30-second hack later, and you've claimed another fast travel point.
Difficulty: Moderate
Start at Carcadia Faction Town and drive your vehicle toward the hilltop settlement ruins. Once there, look north for a significant gap. Execute a boosted vehicle jump to cross - alternatively, use double-jump and glide combinations if you've upgraded movement abilities. The console sits just beyond the gap.
After extensive testing, I've developed the optimal route for claiming all Order Silos efficiently:
You don't need to eliminate all enemies to claim Order Silos. Use these tactics:
For optimal Order Silo runs, I recommend:
Order Silos directly tie into Borderlands 4's endgame Vault system. Each activated Silo reveals one of three Vault Key Fragments needed per region. The detection radius appears as a glowing circle on your map - the Fragment hides somewhere within. A proximity meter on your screen's right side fills with yellow pips as you approach.
Without Order Silo activation, finding Vault Fragments requires pure luck or external guides. The Primordial Vaults unlocked by complete Fragment sets contain the game's best loot, including guaranteed legendary drops and exclusive cosmetics.
With 360 SDU tokens from all Order Silos, strategic spending maximizes your efficiency:
Some Silos hide consoles in unexpected locations. Deathright's infamous mislabeled map position causes the most confusion. Always check elevated positions and use your scanner (L1/LB on consoles) to highlight interactive objects.
Return when you're 2-3 levels higher, or switch to a lower difficulty temporarily. Order Silos remain available throughout the game - there's no time limit or missable window.
Occasionally, the balloon animation glitches. Fast travel away and return to reset the instance. The Silo remains captured, and the balloon should appear correctly.
Join the conversation and get additional help finding Order Silos:
No, Order Silos can be claimed in any sequence. However, following the numbered order typically aligns with natural level progression, making enemies more manageable.
Yes, Vault Fragments exist in the world regardless of Silo activation. Silos simply reveal their approximate locations, making them significantly easier to find. Dedicated explorers can locate Fragments independently.
The Silo still provides its 40 SDU token reward, fast travel point, and vending machine access. Only the Fragment detection feature becomes redundant.
No, Order Silos are entirely optional side content. However, the rewards significantly enhance your character's power and quality of life, making them highly recommended.
Once claimed, Order Silos remain permanently under your control. Enemies may respawn in the area, but the console stays hacked and functional.
Yes, starting a new playthrough or True Vault Hunter Mode resets all Order Silos, allowing you to reclaim them for additional SDU tokens on the same character.
The Stockroom in Fadefields offers the easiest introduction to the mechanic. For maximum benefit, prioritize Silos near areas where you frequently farm or complete missions.
Fast travel points are individual to each player. Co-op partners must activate Order Silos in their own game to unlock the fast travel functionality, though they'll receive SDU rewards if present during initial activation.
Mastering Order Silo locations transforms your Borderlands 4 experience from a grinding trek across Kairos into an efficient, rewarding adventure. These nine structures provide 360 SDU tokens, complete fast travel coverage, essential Vault Fragment hints, and the satisfaction of completing the Balloonacy Challenge.
Whether you're a completionist hunting every achievement or a casual player seeking quality-of-life improvements, Order Silos deserve priority attention. The time invested in claiming all nine pays dividends throughout your entire playthrough and beyond into endgame content.
Remember to bookmark this guide for reference during your Kairos exploration. With September 2025 bringing new updates and potential additional Silos through DLC, staying informed ensures you never miss these valuable opportunities. Happy hunting, Vault Hunters - may your SDU tokens be plentiful and your fast travel network complete!
