Borderlands 4: How to Get SDU Tokens

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.

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.

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.
