Borderlands 4: How to Get SDU Tokens
137
SDU tokens are essential for upgrading your character in Borderlands 4. They let you carry more ammo, expand your backpack space, and increase bank storage. With so many different ways to earn them across Kairos, it can be tricky to know where to start. This guide highlights the most reliable methods, from quick and easy farming options to more challenging activities for advanced players.
What is SDU Token
Storage Deck Upgrades (SDUs) are tokens used to expand your character’s carrying capacity. With them, you can upgrade ammo limits, backpack slots, bank storage, and lost loot. Each upgrade costs more than the last, so smart spending is key.
Best Ways to Get SDU Tokens in Borderlands 4
The simplest way to get SDU tokens in Borderlands 4 is to focus on activities that are fast, repeatable, and always worth the time. These are designed to give you quick SDU chunks without throwing you into endless boss fights or complicated dungeons.
| Point | Location | Action |
| Safehouses | Across all regions | Capture them by finding a Datapad and activating the command console. Rewards 40 SDU and unlocks fast travel. |
| Order Silos | Across all regions | Similar to Safehouses, each Silo nets 40 SDU and unlocks a fast travel hub. |
| Vault Symbols | Scattered walls, major hubs | Interact with glowing graffiti-like symbols. Each gives 5 SDU. |
| Evocarium Puzzles | Various landmarks | Collect three orbs around a pedestal, then activate it for 15 SDU. |
| Lost Capsules | Random field spawns | Carry capsules back to Safehouses to unlock 15 SDU and loot drops. |
Note: Safehouses and Silos are the most efficient since they also improve map mobility. Vault Symbols are the least rewarding individually but stack up across the campaign.
Hardcore Ways to Get SDU Tokens in Borderlands 4
If you want to maximize SDU gains and are ready for bigger fights, these tougher side activities give the best payouts. They demand more combat power, puzzle-solving, or endurance.
| Point | Location | Action |
| Order Bunkers | Across all regions | Mini-dungeons with enemies, puzzles, and bosses. Reward 40 SDU on completion. |
| Abandoned Auger Mines | Fadefields, Carcadia, Dominion | Long dungeons with environmental hazards and final bosses. Reward 40 SDU. |
| Ripper Drill Sites | Across multiple zones | Kill waves of enemies until a mini-boss spawns. Defeat them for 40 SDU. |
| Ancient Crawlers | Massive vehicles in Kairos | Climb to the top, clear enemies, and power them up for 40 SDU. |
| Propaganda Speakers | 27 scattered locations | Hack speakers while fending off enemy waves. Each nets 20 SDU. |
Note: Hardcore methods aren’t required early game. Save these for when you need bulk upgrades or if you’re looking for challenges alongside rewards.
Beginner Tips
Even if you know where to get tokens, getting around and running the game smoothly makes the grind easier. Two beginner tips stand out: performance tuning and vehicle use.
Borderlands 4 isn’t perfectly optimized on PC, that’s why you can do it customly by yourself. Many players report stuttering or low framerates even with modern GPUs. Instead of using Low/Medium/High presets, mix settings manually. Adjust shadows, volumetric fog, and draw distance separately while keeping texture quality high. This balance stabilizes frame pacing across RTX 20–50 cards.
You unlock your first ride, MAV-880 Digirunner bike, during the third main mission Down and Outbound. After meeting Rush and Conway in Crimson Resistance HQ, you’ll get the bike permanently. Summon it with X on PC or Left D-Pad on consoles. The Digirunner comes with boost, drift, jump, and light weapons, making it perfect for cutting across Kairos quickly. Vehicles are essential for reaching Safehouses, Silos, and collectible spots efficiently, so don’t skip the mission.
